Title: Flexible containers with reinforcing seals

Description:
FIELD 
     The present disclosure relates in general to flexible containers, and in particular, to flexible containers having reinforcing seals. 
     BACKGROUND 
     Fluent products include liquid products and/or pourable solid products. In various embodiments, a container can be used to receive, contain, and dispense one or more fluent products. And, in various embodiments, a container can be used to receive, contain, and/or dispense individual articles or separately packaged portions of a product. A container can include one or more product spaces. A product space can be configured to be filled with one or more fluent products. A container receives a fluent product when its product space is filled. Once filled to a desired volume, a container can be configured to contain the fluent product in its product space, until the fluent product is dispensed. A container contains a fluent product by providing a barrier around the fluent product. The barrier prevents the fluent product from escaping the product space. The barrier can also protect the fluent product from the environment outside of the container. A filled product space is typically closed off by a cap or a seal. A container can be configured to dispense one or more fluent products contained in its product space(s). Once dispensed, an end user can consume, apply, or otherwise use the fluent product(s), as appropriate. In various embodiments, a container may be configured to be refilled and reused or a container may be configured to be disposed of after a single fill or even after a single use. A container should be configured with sufficient structural integrity, such that it can receive, contain, and dispense its fluent product(s), as intended, without failure. 
     A container for fluent product(s) can be handled, displayed for sale, and put into use. A container can be handled in many different ways as it is made, filled, decorated, packaged, shipped, and unpacked. A container can experience a wide range of external forces and environmental conditions as it is handled by machines and people, moved by equipment and vehicles, and contacted by other containers and various packaging materials. A container for fluent product(s) should be configured with sufficient structural integrity, such that it can be handled in any of these ways, or in any other way known in the art, as intended, without failure. 
     A container can also be displayed for sale in many different ways as it is offered for purchase. A container can be offered for sale as an individual article of commerce or packaged with one or more other containers or products, which together form an article of commerce. A container can be offered for sale as a primary package with or without a secondary package. A container can be decorated to display characters, graphics, branding, and/or other visual elements when the container is displayed for sale. A container can be configured to be displayed for sale while laying down or standing up on a store shelf, while presented in a merchandising display, while hanging on a display hanger, or while loaded into a display rack or a vending machine. A container for fluent product(s) should be configured with a structure that allows it to be displayed in any of these ways, or in any other way known in the art, as intended, without failure. 
     A container can also be put into use in many different ways, by its end user. A container can be configured to be held and/or gripped by an end user, so a container should be appropriately sized and shaped for human hands; and for this purpose, a container can include useful structural features such as a handle and/or a gripping surface. A container can be stored while laying down or standing up on a support surface, while hanging on or from a projection such as a hook or a clip, or while supported by a product holder, or (for refillable or rechargeable containers) positioned in a refilling or recharging station. A container can be configured to dispense fluent product(s) while in any of these storage positions or while being held by the user. A container can be configured to dispense fluent product(s) through the use of gravity, and/or pressure, and/or a dispensing mechanism, such as a pump, or a straw, or through the use of other kinds of dispensers known in the art. Some containers can be configured to be filled and/or refilled by a seller (e.g. a merchant or retailer) or by an end user. A container for fluent product(s) should be configured with a structure that allows it to be put to use in any of these ways, or in any other way known in the art, as intended, without failure. A container can also be configured to be disposed of by the end user, as waste and/or recyclable material, in various ways. 
     One conventional type of container for fluent products is a rigid container made from solid material(s). Examples of conventional rigid containers include molded plastic bottles, glass jars, metal cans, cardboard boxes, etc. These conventional rigid containers are well-known and generally useful; however their designs do present several notable difficulties. 
     First, some conventional rigid containers for fluent products can be expensive to make. Some rigid containers are made by a process shaping one or more solid materials. Other rigid containers are made with a phase change process, where container materials are heated (to soften/melt), then shaped, then cooled (to harden/solidify). Both kinds of making are energy intensive processes, which can require complex equipment. 
     Second, some conventional rigid containers for fluent products can require significant amounts of material. Rigid containers that are designed to stand up on a support surface require solid walls that are thick enough to support the containers when they are filled. This can require significant amounts of material, which adds to the cost of the containers and can contribute to difficulties with their disposal. 
     Third, some conventional rigid containers for fluent products can be difficult to decorate. The sizes, shapes, (e.g. curved surfaces) and/or materials of some rigid containers, make it difficult to print directly on their outside surfaces. Labeling requires additional materials and processing, and limits the size and shape of the decoration. Overwrapping provides larger decoration areas, but also requires additional materials and processing, often at significant expense. 
     Fourth, some conventional rigid containers for fluent products can be prone to certain kinds of damage. If a rigid container is pushed against a rough surface, then the container can become scuffed, which may obscure printing on the container. If a rigid container is pressed against a hard object, then the container can become dented, which may look unsightly. And if a rigid container is dropped, then the container can rupture, which may cause its fluent product to be lost. 
     Fifth, some fluent products in conventional rigid containers can be difficult to dispense. When an end user squeezes a rigid container to dispense its fluent product, the end user must overcome the resistance of the rigid sides, to deform the container. Some users may lack the hand strength to easily overcome that resistance; these users may dispense less than their desired amount of fluent product. Other users may need to apply so much of their hand strength, that they cannot easily control how much they deform the container; these users may dispense more than their desired amount of fluent product. 
     Sixth, when using conventional rigid containers, it can be difficult for a manufacturer to change such containers from one product size to another product size. When a product manufacturer offers a fluent product in a conventional rigid container, and the manufacturer needs to change the size of the product, the change usually requires the manufacturer to make and use a new size of container for the new amount. Unfortunately, making a new size of that container can be costly, time-consuming, and challenging to coordinate. 
     SUMMARY 
     The present disclosure describes various embodiments of containers made from flexible material. Because these containers are made from flexible material, these containers offer a number of advantages, when compared with conventional rigid containers. 
     First, these containers can be less expensive to make, because the conversion of flexible materials (from sheet form to finished goods) generally requires less energy and complexity, than formation of rigid materials (from bulk form to finished goods). Second, these containers can use less material, because they are configured with novel support structures that do not require the use of the thick solid walls used in conventional rigid containers. Third, these flexible containers can be easier to print and/or decorate, because they are made from flexible materials, and flexible materials can be printed and/or decorated as conformable webs, before they are formed into containers. Fourth, these flexible containers can be less prone to scuffing, denting, and rupture, because flexible materials allow their outer surfaces to deform when contacting surfaces and objects, and then to bounce back. Fifth, fluent products in these flexible containers can be more readily and carefully dispensed, because the sides of flexible containers can be more easily and controllably squeezed by human hands. Even though the containers of the present disclosure are made from flexible material, they can be configured with sufficient structural integrity, such that they can receive, contain, and dispense fluent product(s), as intended, without failure. Also, these containers can be configured with sufficient structural integrity, such that they can withstand external forces and environmental conditions from handling, without failure. Further, these containers can be configured with structures that allow them to be displayed and put into use, as intended, without failure. Sixth, these flexible containers can be configured with easily variable sizing, allowing a product manufacturer to change a product&#39;s size with less expense, in less time, and with less coordination, when compared with conventional rigid containers. 
     A hand-held disposable stand-up flexible container, configured for retail sale, wherein the container comprises: a multiple dose product volume that directly contains a fluent product, wherein about all of the product volume is made from one or more films; a first expanded structural support volume made from portions of one or more first layers of film; a main seal that extends through portions of the one or more first layers of film and also through portions of one or more additional layers of film of the container; and a first reinforcing seal that extends through portions of the one or more first layers of film but not through any portion of the one or more additional layers of film; wherein at least a portion of the first reinforcing seal is disposed between at least a portion of the main seal and at least a portion of the first expanded structural support volume.

     Even though the containers of the present disclosure are made from flexible material, they can be configured with sufficient structural integrity, such that they can receive, contain, and dispense fluent product(s), as intended, without failure. Also, these containers can be configured with sufficient structural integrity, such that they can withstand external forces and environmental conditions from handling, without failure. Further, these containers can be configured with structures that allow them to be displayed for sale and put into use, as intended, without failure. 
     Definitions 
     As used herein, the term “about” modifies a particular value, by referring to a range equal to the particular value, plus or minus twenty percent (+/−20%). For any of the embodiments of flexible containers, disclosed herein, any disclosure of a particular value, can, in various alternate embodiments, also be understood as a disclosure of a range equal to about that particular value (i.e. +/−20%). 
     As used herein, the term “actual amount” refers to a measured amount of the fluent product(s) present in a product space of a container when the container is configured for retail sale. 
     As used herein, the term “ambient conditions” refers to a temperature of 19-21 degrees Celsius and a relative humidity of 45-55%. 
     As used herein, the term “approximately” modifies a particular value, by referring to a range equal to the particular value, plus or minus fifteen percent (+/−15%). For any of the embodiments of flexible containers, disclosed herein, any disclosure of a particular value, can, in various alternate embodiments, also be understood as a disclosure of a range equal to approximately that particular value (i.e. +/−15%). 
     As used herein, the term “atmospheric pressure” refers to an absolute pressure of 1 atmosphere. 
     As used herein, when referring to a sheet of material, the term “basis weight” refers to a measure of mass per area, in units of grams per square meter (gsm). For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any of the flexible materials can be configured to have a basis weight of 10-1000 gsm, or any integer value for gsm from 10-1000, or within any range formed by any of these values, such as 20-800 gsm, 30-600 gsm, 40-400 gsm, or 50-200, etc. 
     As used herein, when referring to a flexible container, the term “bottom” refers to the portion of the container that is located in the lowermost 30% of the overall height of the container, that is, from 0-30% of the overall height of the container. As used herein, the term bottom can be further limited by modifying the term bottom with a particular percentage value, which is less than 30%.

     As used herein, the term “branding” refers to a visual element intended to distinguish a product from other products. Examples of branding include one of more of any of the following: trademarks, trade dress, logos, icons, and the like. For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any surface of the flexible container can include one or more brandings of any size, shape, or configuration, disclosed herein or known in the art, in any combination. 
     As used herein, the term “character” refers to a visual element intended to convey information. Examples of characters include one or more of any of the following: letters, numbers, symbols, and the like. For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any surface of the flexible container can include one or more characters of any size, shape, or configuration, disclosed herein or known in the art, in any combination. 
     As used herein, the term “closed” refers to a state of a product space, wherein fluent products within the product space are prevented from escaping the product space (e.g. by one or more materials that form a barrier), but the product space is not necessarily hermetically sealed. For example, a closed container can include a vent, which allows a head space in the container to be in fluid communication with air in the environment outside of the container. 
     As used herein, the term “closed fill height” refers to a distance that is measured when the container is configured for retail sale and while the container is standing upright on a horizontal support surface, the distance measured vertically from the upper side of the support surface to a fill line in a product space of the container. If a container does not have a standing upright orientation but does have a hanging orientation, then the term closed fill height refers to a distance that is measured when the container is configured for retail sale and while the container is hanging down from a support, the distance measured vertically from the lowest point on the container to a fill line in a product space of the container. If a container does not have a standing upright orientation or a hanging orientation, then the term closed fill height does not apply to the container. 
     As used herein, the term “deflation feature” refers to one or more structural features provided with a flexible container for use in deflating some or all of the expanded structural support volume(s) of the flexible container, by allowing expansion material(s) inside of the structural support volume to escape into the environment, so that the structural support volume is no longer expanded. A deflation feature can be used when the flexible container is ready to be disposed of (i.e. as waste, compost, and/or recyclable material). Any of the flexible containers disclosed herein can be configured with any number of any kind of deflation feature, configured in any way disclosed herein or known in the art. 
     One kind of deflation feature is a cutting device, which is a rigid element that includes a point or edge configured to cut and/or pierce through flexible material(s) that form at least part of a structural support volume. As an example, a cutting device can be included with a flexible container by attaching the device to any portion of the outside (e.g. top, middle, side, bottom, etc.) of the container with adhesive, or under a label, or any other way known in the art, for externally attaching rigid elements to a container. As another example, a cutting device can be included with a flexible container by including the device with other packaging material, such as attached to an outer carton, inside of an overwrap layer, in between containers provided together, etc. As still another example, a cutting device can be included with a flexible container by including the device inside of any portion of the container, such as in a product space, in a structural support volume, in a mixing chamber, in a dedicated space for the device, in a base structure, or any other way known in the art, for internally including rigid elements within a container. As yet another example, a cutting device can be included with a flexible container, by making the cutting device integral with or detachable from another rigid element that is part of the container, such as a rigid base structure, cap, dispenser, fitment, connecting element, reinforcing element, or any other rigid element for containers disclosed herein or known in the art. A cutting device can be configured to be any convenient size and any workable shape and can be used manually or through use of a tool. In addition to rigid elements, flexible materials that can be turned into a rigid cutting device through rolling up or folding flexible materials are also envisioned. 
     Another kind of deflation feature is an exit channel, which can be configured to be opened in material(s) that border or define at least a portion of the fillable space of a structural support volume. An exit channel can be an existing connection (e.g. seam, seal, or joint) in the container, which is configured to fail (e.g. separate and at least partially open) when exposed to opening forces. An exit channel can also be formed with one or more points, lines, and/or areas of weakness (e.g. thinned, scored, perforated, frangible seal, etc.), which are configured to fail or to otherwise be breached, when exposed to opening forces. An exit channel can be protected by another material, such as an adhesive label, to ensure the exit channel remains closed until the user wishes to deflate. An exit channel can further be formed by configuring the container with one or more tear initiation sites (such as a notch in an edge, a pull-tab, etc.) such that a tear propagating from the site(s) can open the flexible material. An exit channel can be configured to be any convenient size and any workable shape and can be opened manually (by grasping and pulling, by poking with a finger or fingernail, or any other way) or through use of a tool or by overpressurizing a structural support volume (through application of compressive force or controlled environmental conditions) such that the structural support volume fails when its expansion material(s) burst out. 
     Still another kind of deflation feature is a valve, connected to the fillable space of a structural support volume, wherein the valve can be opened to the container&#39;s environment. Embodiments of the present disclosure can use as a deflation feature, any and all embodiments of valves (including materials, structures, and/or features for valves, as well as any and all methods of making and/or using such valves), as disclosed in the following patent documents: U.S. nonprovisional patent application Ser. No. 13/379,655 filed Jun. 21, 2010, entitled “Collapsible Bottle, Method Of Manufacturing a Blank For Such Bottle and Beverage-Filled Bottle Dispensing System” in the name of Reidl, published as US2012/0097634; U.S. nonprovisional patent application Ser. No. 10/246,893 filed Sep. 19, 2002, entitled “Bubble-Seal Apparatus for Easily Opening a Sealed Package” in the name of Perell, et al., published as 20040057638; and U.S. Pat. No. 7,585,528 filed Dec. 16, 2002, entitled “Package having an inflated frame” in the name of Ferri, et al., granted on Sep. 8, 2009; each of which is hereby incorporated by reference. 
     As used herein, the term “directly connected” refers to a configuration wherein elements are attached to each other without any intermediate elements therebetween, except for any means of attachment (e.g. adhesive). 
     As used herein, when referring to a flexible container, the term “dispenser” refers to a structure configured to dispense fluent product(s) from a product space and/or from a mixing volume to the environment outside of the container. For any of the flexible containers disclosed herein, any dispenser can be configured in any way disclosed herein or known in the art, including any suitable size, shape, and flow rate. For example, a dispenser can be a push-pull type dispenser, a dispenser with a flip-top cap, a dispenser with a screw-on cap, a rotatable type dispenser, dispenser with a cap, a pump type dispenser, a pump spray type dispenser, a trigger spray type dispenser, a straw dispenser, a flip up straw dispenser, a straw dispenser with bite valve, a dosing dispenser, etc. A dispenser can be a parallel dispenser, providing multiple flow channels in fluid communication with multiple product spaces, wherein those flow channels remain separate until the point of dispensing, thus allowing fluent products from multiple product spaces to be dispensed as separate fluent products, dispensed together at the same time. A dispenser can be a mixing dispenser, providing one or more flow channels in fluid communication with multiple product spaces, with multiple flow channels combined before the point of dispensing, thus allowing fluent products from multiple product spaces to be dispensed as the fluent products mixed together. As another example, a dispenser can be formed by a frangible opening. As further examples, a dispenser can utilize one or more valves and/or dispensing mechanisms disclosed in the art, such as those disclosed in: published US patent application 2003/0096068, entitled “One-way valve for inflatable package”; U.S. Pat. No. 4,988,016 entitled “Self-sealing container”; and U.S. Pat. No. 7,207,717, entitled “Package having a fluid actuated closure”; each of which is hereby incorporated by reference. Still further, any of the dispensers disclosed herein, may be incorporated into a flexible container either directly, or in combination with one or more other materials or structures (such as a fitment), or in any way known in the art. In some alternate embodiments, dispensers disclosed herein can be configured for both dispensing and filling, to allow filling of product space(s) through one or more dispensers. In other alternate embodiments, a product space can include one or more filling structure(s) (e.g. for adding water to a mixing volume) in addition to or instead of one or more dispenser(s). Any location for a dispenser, disclosed herein can alternatively be used as a location for a filling structure. In some embodiments, a product space can include one or more filling structures in addition to any dispenser(s). And, any location for a dispenser, disclosed herein can alternatively be used as a location for an opening, through which product can be filled and/or dispensed, wherein the opening may be reclosable or non-reclosable, and can be configured in any way known in the art of packaging. For example, an opening can be: a line of weakness, which can be torn open; a zipper seal, which can be pulled open and pressed closed (e.g. a press seal), or opened and closed with a slider; openings with adhesive-based closures; openings with cohesive-based closures; openings with closures having fasteners (e.g. snaps, tin tie, etc.), openings with closures having micro-sized fasteners (e.g. with opposing arrays of interlocking fastening elements, such as hook, loops, and/or other mating elements, etc.), and any other kind of opening for packages or containers, with or without a closure, known in the art. 
     As used herein, when referring to a flexible container, the term “disposable” refers to a container which, after dispensing a product to an end user, is not configured to be refilled with an additional amount of the product, but is configured to be disposed of (i.e. as waste, compost, and/or recyclable material). Part, parts, or all of any of the embodiments of flexible containers, disclosed herein, can be configured to be disposable. 
     As used herein, when referring to a flexible container, the term “durable” refers to a container that is reusable more than non-durable containers. 
     As used herein, when referring to a flexible container, the term “effective base contact area” refers to a particular area defined by a portion of the bottom of the container, when the container is configured for retail sale and is standing upright and its bottom is resting on a horizontal support surface, determined as described below. The effective base contact area lies in a plane defined by the horizontal support surface. The effective base contact area is a continuous area bounded on all sides by an outer periphery. 
     The outer periphery is formed from an actual contact area and from a series of projected areas from defined cross-sections taken at the bottom of the container. The actual contact area is the one or more portions of the bottom of the container that contact the horizontal support surface, when the effective base contact area is defined. The effective base contact area includes all of the actual contact area. However, in some embodiments, the effective base contact area may extend beyond the actual contact area. 
     The series of projected area are formed from five horizontal cross-sections, taken at the bottom of the flexible container. These cross-sections are taken at 1%, 2%, 3%, 4%, and 5% of the overall height. The outer extent of each of these cross-sections is projected vertically downward onto the horizontal support surface to form five (overlapping) projected areas, which, together with the actual contact area, form a single combined area. This is not a summing up of the values for these areas, but is the formation of a single combined area that includes all of these (projected and actual) areas, overlapping each other, wherein any overlapping portion makes only one contribution to the single combined area. 
     The outer periphery of the effective base contact area is formed as described below. In the following description, the terms convex, protruding, concave, and recessed are understood from the perspective of points outside of and around the combined area. The outer periphery is formed by a combination of the outer extent of the combined area and any chords, which are straight line segments constructed as described below. 
     For each continuous portion of the combined area that has an outer perimeter with a shape that is concave or recessed, a chord is constructed across that portion. This chord is the shortest straight line segment that can be drawn tangent to the combined area on both sides of the concave/recessed portion. 
     For a combined area that is discontinuous (formed by two or more separate portions), one or more chords are constructed around the outer perimeter of the combined area, across the one or more discontinuities (open spaces disposed between the portions). These chords are straight line segments drawn tangent to the outermost separate portions of the combined area. These chords are drawn to create the largest possible effective base contact area. 
     Thus, the outer periphery is formed by a combination of the outer extent of the combined area and any chords, constructed as described above, which all together enclose the effective base area. Any chords that are bounded by the combined area and/or one or more other chords, are not part of the outer periphery and should be ignored. 
     Any of the embodiments of flexible containers, disclosed herein, can be configured to have an effective base contact area from 1 to 50,000 square centimeters (cm 2 ), or any integer value for cm 2  between 1 and 50,000 cm 2 , or within any range formed by any of the preceding values, such as: from 2 to 25,000 cm 2 , 3 to 10,000 cm 2 , 4 to 5,000 cm 2 , 5 to 2,500 cm 2 , from 10 to 1,000 cm 2 , from 20 to 500 cm 2 , from 30 to 300 cm 2 , from 40 to 200 cm 2 , or from 50 to 100 cm 2 , etc. 
     As used herein, when referring to a flexible container, the term “expanded” refers to the state of one or more flexible materials that are configured to be formed into a structural support volume, after the structural support volume is made rigid by one or more expansion materials. An expanded structural support volume has an overall width that is significantly greater than the combined thickness of its one or more flexible materials, before the structural support volume is filled with the one or more expansion materials. Examples of expansion materials include liquids (e.g. water), gases (e.g. compressed air), fluent products, foams (that can expand after being added into a structural support volume), co-reactive materials (that produce gas), or phase change materials (that can be added in solid or liquid form, but which turn into a gas; for example, liquid nitrogen or dry ice), or other suitable materials known in the art, or combinations of any of these (e.g. fluent product and liquid nitrogen). In various embodiments, expansion materials can be added at atmospheric pressure, or added under pressure greater than atmospheric pressure, or added to provide a material change that will increase pressure to something above atmospheric pressure. For any of the embodiments of flexible containers, disclosed herein, its one or more flexible materials can be expanded at various points in time, with respect to its manufacture, sale, and use, including, for example: before or after its product space(s) are filled with fluent product(s), before or after the flexible container is shipped to a seller, and before or after the flexible container is purchased by an end user. 
     As used herein, when referring to a container for retail sale of one or more fluent products, the term “external amount indicium” refers to an indicium that is joined to the container, that is visible from outside of the container, and that indicates a listed amount of fluent product that is being offered for sale with the container. The indicium can be any kind of indicium described herein or known in the art. In various embodiments, the indicium can be a particular value in various units of measurement (e.g. milliliters and/or fluid ounces for a fluent product that is a liquid; grams and/or ounces of weight for a fluent product that is a pourable solid). In various embodiments, the indicium can be for a particular product size that is associated with a particular amount of fluent product being offered for sale. The indicium can be provided on a label or as printing or in any other form described herein or known in the art. The indicium can be joined to an outside of the container or joined to an inside of the container (and visible through a transparent portion of the container), or on secondary packaging connected to the container. Alternatively, instead of being joined to the container, the indicium can be presented as part of a merchandising display for the container or can be communicated via advertising materials. An external amount indicium is typically applied to a container by the manufacturer of the product or by a retailer of the product. 
     Although a manufacturer may earnestly endeavor to make products that are properly filled and accurately labeled, there may be some limited instances, in which a container may contain an actual amount of fluent product that is not exactly equal to the listed amount of fluent product indicated by its external amount indicium. As a first example, a manufacturer may intentionally overfill containers, in an attempt to make up for projected losses of fluent product (from evaporation) during their shelf life. As a second example, a manufacturer may experience variability in the filling of containers, resulting in a few containers having actual amounts of fluent product that vary somewhat from a targeted amount of fill. As a third example, a retailer may unintentionally sell a product that has passed its expected shelf life, and has experienced a larger than projected loss of fluent product (from evaporation). Despite these limited instances, a container offered for retail sale typically contains an actual amount of fluent product that is nearly equal to the listed amount of fluent product indicated by its external amount indicium. 
     As used herein, when referring to a product space of a flexible container, the term “filled” refers to the state of the product space in the container (which is fully manufactured) after the filling of its product space(s) with fluent product(s) is complete and the container is fully closed and/or sealed, wherein the container has not been opened or unsealed, and wherein the fluent product(s) in the container have not been put into its/their intended end use. 
     A filled product space may or may not include an allowance for headspace, depending on the kind of fluent product(s) being contained, and the requirements for containing the fluent product(s). As an example, a manufacturer can label a flexible container with an external amount indicium that indicates a listed amount of a fluent product that is being offered for sale with the container, can add to the product space of the container an actual amount of the fluent product that is nearly equal to the listed amount (but still includes a headspace that is designed for that fluent product in that product space), and can close the container so the container is configured for retail sale; that container is considered filled. As used herein, the term filled can be modified by using the term filled with a particular percentage value. 
     As used herein, the term “flat” refers to a surface that is without significant projections or depressions. 
     As used herein, the term “flexible container” refers to a container with a product space, wherein one or more flexible materials form 50-100% of the overall surface area of the one or more materials that define the three-dimensional space of the product space. For any of the embodiments of flexible containers, disclosed herein, in various embodiments, the flexible container can be configured to have a product space, wherein one or more flexible materials form a particular percentage of the overall area of the one or more materials that define the three-dimensional space, and the particular percentage is any integer value for percentage between 50% and 100%, or within any range formed by any of these values, such as: 60-100%, or 70-100%, or 80-100%, or 90-100%, etc. One kind of flexible container is a film-based container, which is a flexible container made from one or more flexible materials, which include a film. 
     For any of the embodiments of flexible containers, disclosed herein, in various embodiments, the middle of the flexible container (apart from any fluent product) can be configured to have an overall middle mass, wherein one or more flexible materials form a particular percentage of the overall middle mass, and the particular percentage is any integer value for percentage between 50% and 100%, or within any range formed by any of the preceding values, such as: 60-100%, or 70-100%, or 80-100%, or 90-100%, etc. 
     For any of the embodiments of flexible containers, disclosed herein, in various embodiments, the entire flexible container (apart from any fluent product) can be configured to have an overall mass, wherein one or more flexible materials form a particular percentage of the overall mass, and the particular percentage is any integer value for percentage between 50% and 100%, or within any range formed by any of the preceding values, such as: 60-100%, or 70-100%, or 80-100%, or 90-100%, etc. 
     As used herein, when referring to a flexible container, the term “flexible material” refers to a thin, easily deformable, sheet-like material, having a flexibility factor within the range of 1,000-2,500,000 N/m.

     As used herein, the term “overall external displacement” refers to a total volume of a flexible container that is configured for retail sale, when measured according to the following test method for displacement. The test method for displacement is used on one flexible container at a time. Before the testing begins, all secondary packaging is removed from the flexible container; however, the flexible container is neither opened nor unsealed before the testing. The test method for displacement is performed under ambient conditions and at atmospheric pressure. The flexible container is fully submerged in a rigid open container of distilled water that has a temperature of 19-21 degrees Celsius. While the flexible container is submerged, the size and shape of the flexible container must not be artificially distorted by any part of the testing equipment. Before the displacement is measured, any air pockets trapped beneath the flexible container must be removed; also any large bubbles (having diameter greater than 1 centimeter) in the water must be removed. When the displacement is measured, the flexible container is fully submerged, in a standing orientation on a bottom of the rigid open container, and submerged to a depth such that an uppermost portion of the flexible container is 1-5 centimeters beneath the surface of the water. The overall external displacement of the flexible container is measured by determining how much water is displaced by the flexible container when the flexible container is fully submerged, as described above.

     Together,  FIGS. 15A-15C  illustrate an embodiment of a conventional rigid container wherein fill height varies in proportion to the amount of fluent product in the container&#39;s product spaces. 
       FIG. 15A  illustrates a front view of a rigid container  1500 - a , having a first actual amount of a liquid fluent product  1551 - a , according to the prior art. The rigid container  1500 - a  is a conventional molded bottle, with a top, bottom, and an outer wall  1580 - a , together forming an overall shape that is cylindrical. The rigid container  1500 - a  is standing upright with its bottom resting on a horizontal support surface  1501 . The rigid container  1500 - a  includes a product space  1550 - a  that is visible in  FIG. 15A  through a portion of the outer wall  1580 - a  that is illustrated as broken away. The product space  1550 - a  has a particular size and is also cylindrical. The fluent product  1551 - a  is disposed in the product space  1550 - a . The top of the rigid container  1500 - a  includes a dispenser  1560 - a  that is closed by a cap. An external amount indicium  1530 - a  is disposed on the outside of the outer wall  1580 - a . The external amount indicium  1530 - a  indicates a particular listed amount (designated “X”) of the fluent product  1551 - a  that is being offered for sale with the container  1500 - a . In the embodiment of  FIG. 15A , the rigid container  1500 - a  contains a first actual amount of the fluent product  1551 - a , wherein the first actual amount is equal to the particular listed amount indicated by the external amount indicium  1530 - a . Inside the product space  1550 - a , the fluent product  1551 - a  forms a fill line  1554 - a  at a closed fill height  1555 - a ; the fluent product  1551 - a  sits below the fill line  1554 - a  and a headspace  1558 - a  exists above the fill line  1554 - a . Since the product space  1550 - a  is cylindrical, the first actual amount of the fluent product  1551 - a  in the container  1500 - a  is equal to a horizontal cross-sectional area of the product space  1550 - a  multiplied by a vertical height of the fluent product  1551 - a  within the product space  1550 - a . As a result, for the container  1500 - a , a fill height will vary in proportion to an amount of fluent product in the product space  1550 - a.    
       FIG. 15B  illustrates a front view of a rigid container  1500 - b , having a second amount of a liquid fluent product  1551 - b , according to the prior art. The rigid container  1500 - b  is the same as the rigid container  1500 - a  of  FIG. 15A , with like-numbered elements configured in the same way, except as described below. The external amount indicium  1530 - b  indicates a particular listed amount (designated “&gt;&gt;X”) of the fluent product  1551 - b  that is being offered for sale with the container  1500 - b . In the embodiment of  FIG. 15B , the rigid container  1500 - b  contains a second actual amount of the fluent product  1551 - b , wherein the second actual amount is equal to the particular listed amount indicated by the external amount indicium  1530 - b . In  FIG. 15B , the second listed amount of the fluent product  1551 - b  is greater than the first listed amount of the fluent product  1551 - a  of  FIG. 15A , and the second actual amount of the fluent product  1551 - b  in the container  1500 - b  is greater than the first actual amount of the fluent product  1551 - a  in the container  1500 - a  of  FIG. 15A . The fluent product  1551 - b  forms a fill line  1554 - b  at a closed fill height  1555 - b . Since the product space  1550 - b  is the same size and shape as the product space  1550 - a , the closed fill height  1555 - b  is higher than the closed fill height  1555 - a  of  FIG. 15A . The closed fill height  1555 - b  is greater than the closed fill height  1555 - a  in the same proportion that the second actual amount of the fluent product  1551 - b  is greater than the first actual amount of the fluent product  1551 - a.    
       FIG. 15C  illustrates a front view of a rigid container  1500 - c , having a third amount of a liquid fluent product  1551 - c , according to the prior art. The rigid container  1500 - c  is the same as the rigid container  1500 - a  of  FIG. 15A , with like-numbered elements configured in the same way, except as described below. The external amount indicium  1530 - c  indicates a particular listed amount (designated “&lt;&lt;X”) of the fluent product  1551 - c  that is being offered for sale with the container  1500 - c . In the embodiment of  FIG. 15C , the rigid container  1500 - c  contains a third actual amount of the fluent product  1551 - c , wherein the third actual amount is equal to the particular listed amount indicated by the external amount indicium  1530 - c . In  FIG. 15C , the third actual amount of the fluent product  1551 - c  in the container  1500 - c  is less than the first actual amount of the fluent product  1551 - a  in the container  1500 - a  of  FIG. 15A . The fluent product  1551 - c  forms a fill line  1554 - c  at a closed fill height  1555 - c  above the horizontal support surface  1501 . Since the product space  1550 - c  is the same size and shape as the product space  1550 - a , the closed fill height  1555 - c  is lower than the closed fill height  1555 - a  of  FIG. 15A . The closed fill height  1555 - c  is less than the closed fill height  1555 - a  in the same proportion that the third actual amount of the fluent product  1551 - c  is less than the first actual amount of the fluent product  1551 - a.    
       FIGS. 16A-16D  illustrate flexible containers with fluent product, wherein the containers are in various conditions of being opened or closed, sealed or vented. 
       FIG. 16A  illustrates a front view of a flexible container  1600 - a , which is closed and sealed by a cap  1661 - a . The flexible container  1600 - a  is the same as the flexible container  200  of  FIGS. 2A-2D , with like-numbered elements configured in the same way, except as described below. The container  1600 - a  is standing upright with its bottom resting on a horizontal support surface  1601 . The flexible container  1600 - a  includes a product space  1650 - a  that is visible in  FIG. 16A  through a transparent panel  1680 - a  that is illustrated as partially broken away. A fluent product  1651 - a  is disposed in the product space  1650 - a . The top of the flexible container  1600 - a  includes a dispenser  1660 - a  that is closed and sealed by the cap  1661 - a . Inside the product space  1650 - a , the fluent product  1651 - a  forms a fill line  1654 - a  at a closed and sealed fill height  1655 - a ; the fluent product  1651 - a  sits below the fill line  1654 - a  and a headspace  1658 - a  exists above the fill line  1654 - a . Since the flexible container  1600 - a  is closed and sealed, the product space  1650 - a  (including the headspace  1658 - a ) is hermetically sealed, with respect to the environment outside of the container  1600 - a . As a result of being sealed, the pressure in the headspace  1658 - a  is not free to equalize with the pressure of the environment outside of the container  1600 - a . So, the fill line  1654 - a  does not move up or down from any pressure equalization, and the closed and sealed fill height  1655 - a  tends to remain relatively fixed. Any embodiment of flexible container disclosed herein, can also be configured to be closed and sealed as described in connection with the flexible container  1600 - a  of  FIG. 16A , or with any additional or alternate structures described herein, or known in the art. 
       FIG. 16B  illustrates a front view of a flexible container  1600 - b , which is closed by a cap  1661 - b  but vented through the cap  1661 - b . The flexible container  1600 - b  is the same as the flexible container  1600 - a  of  FIG. 16A , with like-numbered elements configured in the same way, except as described below. The container  1600 - a  is standing upright with its bottom resting on a horizontal support surface  1601 . The top of the flexible container  1600 - b  includes a dispenser  1660 - b  that is closed but not sealed by the cap  1661 - b . Inside the product space  1650 - b , the fluent product  1651 - b  forms a fill line  1654 - b  at a closed fill height  1655 - b . Since the flexible container  1600 - b  is closed but not sealed by the cap  1661 - b , the product space  1650 - b  (including the headspace  1658 - b ) is in fluid communication  1669 - b , through the vented cap  1661 - b , with the environment outside of the container  1600 - b . As a result of not being sealed, the pressure in the headspace  1658 - b  can equalize with the pressure of the environment outside of the container  1600 - b . So, the fill line  1654 - b  can move up or down as these pressures equalize, allowing the closed fill height  1655 - b  to vary somewhat. Any embodiment of flexible container disclosed herein can also be configured to be closed but not sealed as described in connection with the flexible container  1600 - b  of  FIG. 16B , or with any additional or alternate structures described herein, or known in the art. When a flexible container that is sealed becomes vented (e.g. by opening a vent in a cap), the pressure in the headspace can equalize with the pressure of the environment, allowing the fill line to move from a closed and sealed fill height to a closed fill height. 
       FIG. 16C  illustrates a front view of the flexible container  1600 - c , which is closed by a cap  1661 - c , but vented through a vent  1665 . The flexible container  1600 - c  is the same as the flexible container  1600 - a  of  FIG. 16A , with like-numbered elements configured in the same way, except as described below. The container  1600 - a  is standing upright with its bottom resting on a horizontal support surface  1601 . The flexible container  1600 - c  includes the vent  1665 . Inside the product space  1650 - c , the fluent product  1651 - c  forms a fill line  1654 - c  at a closed fill height  1655 - c . Since the flexible container  1600 - b  is closed by the cap  1661 - b  but vented through the vent  1665 , the product space  1650 - c  (including the headspace  1658 - c ) is in fluid communication  1669 - c , through the vent  1665 , with the environment outside of the container  1600 - c . As a result of not being sealed, the pressure in the headspace  1658 - c  can equalize with the pressure of the environment outside of the container  1600 - c . So, the fill line  1654 - c  can move up or down as these pressures equalize, allowing the closed fill height  1655 - c  to vary somewhat. Any embodiment of flexible container disclosed herein can also be configured to be closed but vented as described in connection with the flexible container  1600 - c  of  FIG. 16C , or with any additional or alternate structures described herein, or known in the art. When a flexible container that is sealed becomes vented (e.g. by opening a vent in the container), the pressure in the headspace can equalize with the pressure of the environment, allowing the fill line to move from a closed and sealed fill height to a closed fill height. 
       FIG. 16D  illustrates a front view of the flexible container  1600 - d , which is vented through an open dispenser  1660 - d . The flexible container  1600 - d  is the same as the flexible container  1600 - a  of  FIG. 16A , with like-numbered elements configured in the same way, except as described below. The container  1600 - a  is standing upright with its bottom resting on a horizontal support surface  1601 . The top of the flexible container  1600 - d  includes a dispenser  1660 - d  that is open. Inside the product space  1650 - d , the fluent product  1651 - d  forms a fill line  1654 - d  at an open fill height  1655 - d . Since the flexible container  1600 - d  is open and vented through the dispenser  1660 - d , the product space  1650 - d  (including the headspace  1658 - d ) is in fluid communication  1669 - d , through the dispenser  1660 - d , with the environment outside of the container  1600 - d . As a result of not being sealed, the pressure in the headspace  1658 - d  can equalize with the pressure of the environment outside of the container  1600 - d . So, the fill line  1654 - d  can move up or down as these pressures equalize, allowing the open fill height  1655 - d  to vary somewhat. Any embodiment of flexible container disclosed herein can also be configured to be open and vented as described in connection with the flexible container  1600 - d  of  FIG. 16D , or with any additional or alternate structures described herein, or known in the art. When a flexible container that is sealed becomes unsealed (e.g. by opening a dispenser), the pressure in the headspace can also equalize with the pressure of the environment, allowing the fill line to move from a closed and sealed fill height to an open fill height. 
       FIG. 17A  illustrates a front view of a flexible container  1700 - a . The flexible container  1700 - a  is the same as the flexible container  200  of  FIGS. 2A-2D , with like-numbered elements configured in the same way, except as described below.

The product viewing portion  1782 - a  is laterally centered on a top portion of a panel  1780 - a , however a product viewing portion can be disposed on any part of a flexible container. The product viewing portion  1782 - a  is surrounded on all sides by an opaque portion  1781 - a  of the panel  1780 - a , however this particular relationship with surrounding elements is not required. The product space  1750 - a  is filled with a fluent product  1751 - a . Inside the product space  1750 - a , the fluent product  1751 - a  forms a fill line  1754 - a ; the fluent product  1751 - a  sits below the fill line  1754 - a  and a headspace  1758 - a  exists above the fill line  1754 - a . In the embodiment of  FIG. 17A , at least a portion of the fill line  1754 - a  is visible through the product viewing portion  1782 - a , from outside of the flexible container  1700 - a . So, a fill height for the fluent product  1751 - a  can be seen when the product space  1750 - a  of the flexible container  1700 - a  is filled. Any embodiment of a flexible container disclosed herein can include the product viewing portion  1782 - a  as described and illustrated in connection with flexible container  1700 - a  of  FIG. 17A , including any alternative embodiments. 
       FIG. 17B  illustrates a front view of a flexible container  1700 - b . The flexible container  1700 - b  is the same as the flexible container  1700 - a  of  FIG. 17A , with like-numbered elements configured in the same way, except as described below. The flexible container  1700 - b  includes a product space  1750 - b  that is partially visible in  FIG. 17B  through a product viewing portion  1782 - b . The product viewing portion  1782 - b  is made from a flexible material that is transparent. The product viewing portion  1782 - b  is a trapezoidal shaped portion that occupies a top portion of a panel  1780 - b . The product viewing portion  1782 - b  is bounded on its top and sides by an outer extent of the panel  1780 - b  and bounded on its bottom by an opaque portion  1781 - b  of the panel  1780 - b , however this particular relationship with surrounding elements is not required. In the embodiment of  FIG. 17B , all of the fill line  1754 - b  is visible through the product viewing portion  1782 - b , from outside of the flexible container  1700 - b . So, a fill height for the fluent product  1751 - a  can be seen when the product space  1750 - a  of the flexible container  1700 - a  is filled. Any embodiment of a flexible container disclosed herein can include the product viewing portion  1782 - b  as described and illustrated in connection with flexible container  1700 - b  of  FIG. 17B , including any alternative embodiments. 
       FIG. 17C  illustrates a front view of a flexible container  1700 - c . The flexible container  1700 - c  is the same as the flexible container  1700 - a  of  FIG. 17A , with like-numbered elements configured in the same way, except as described below. The flexible container  1700 - b  includes a product space  1750 - c  that is partially visible in  FIG. 17C  through five separate product viewing portions  1782 - c   1 ,  1782 - c   2 ,  1782 - c   3 ,  1782 - c   4 , and  1782 - c   5 . Each of the product viewing portions  1782 - c   1  through  1782 - c   5  is made from a flexible material that is transparent. Each of the product viewing portions  1782 - c   1  through  1782 - c   5  is an oval shaped portion. Each of the product viewing portions  1782 - c   1  through  1782 - c   5  is surrounded on all sides by an opaque portion  1781 - c  of the panel  1780 - c . The product viewing portions  1782 - c   1  through  1782 - c   5  are distributed longitudinally and staggered laterally (with respect to each other), from a top portion of a panel  1780 - c  to a bottom portion of the panel  1780 - c ; however, in various embodiments product viewing portions may not be staggered laterally, or may be distributed over part, parts, or all of a product space or a panel overlaying a product space in any convenient arrangement. In the embodiment of  FIG. 17C , at least a portion of the fill line  1754 - c  is visible through the product viewing portion  1782 - c   1 , from outside of the flexible container  1700 - c . So, a fill height for the fluent product  1751 - c  can be seen in the product viewing portion  1782 - c   1  when the product space  1750 - c  of the flexible container  1700 - c  is filled. And, since the product viewing portions  1782 - c   1  through  1782 - c   5  are distributed from top to bottom, the product viewing portions  1782 - c   1  through  1782 - c   5  allow the fluent product  1751 - c  in the product space  1750 - c  to be seen at a number of locations; a fill height for the fluent product  1751 - a  can also be seen at various ranges of fill heights (corresponding with the heights of the product viewing portions  1782 - c   1  through  1782 - c   5 ) as the flexible container  1750 - c  is emptied. As a result, the product viewing portions  1782 - c   1  through  1782 - c   5  are considered to form a visual fill gauge for the product space  1750 - c . Any embodiment of a flexible container disclosed herein can include any or all of the plurality of product viewing portions  1782 - c   1  through  1782 - c   5  as described and illustrated in connection with flexible container  1700 - b  of  FIG. 17B , including any alternative embodiments.

The flexible container  1700 - d  is the same as the flexible container  1700 - a  of  FIG. 17A , with like-numbered elements configured in the same way, except as described below. The flexible container  1700 - d  includes a product space  1750 - d  that is partially visible in  FIG. 17D  through a product viewing portion  1782 - d . The product viewing portion  1782 - d  is made from a flexible material that is transparent. The product viewing portion  1782 - d  is an elongated, rectangular shaped portion. The product viewing portion  1782 - d  is bounded on its top and bottom by an outer extent of a panel  1780 - d  and bounded on its sides by opaque portions  1781 - d  of the panel  1780 - d . The product viewing portion  1782 - d  extends continuously longitudinally, from a top portion of the panel  1780 - d  to a bottom portion of the panel  1780 - d ; however, in various embodiments an product viewing portion may be discontinuous or may also extend laterally or may extend over part, parts, or all of a product space or a panel overlaying a product space in any convenient arrangement. In the embodiment of  FIG. 17D , at least a portion of the fill line  1754 - d  is visible through a top portion of the product viewing portion  1782 - d , from outside of the flexible container  1700 - d . So, a fill height for the fluent product  1751 - d  can be seen in the product viewing portion  1782 - d  when the product space  1750 - d  of the flexible container  1700 - d  is filled. And, since the product viewing portion  1782 - d  extends continuously from top to bottom, the product viewing portion  1782 - d  allows the fluent product  1751 - d  in the product space  1750 - d  to be seen at a number of locations; a fill height for the fluent product  1751 - d  can also be seen at any fill height as the flexible container  1750 - d  is emptied. As a result, the product viewing portion  1782 - d  is considered to form a visual fill gauge for the product space  1750 - d . Any embodiment of a flexible container disclosed herein can include a product viewing portion  1782 - d  as described and illustrated in connection with flexible container  1700 - d  of  FIG. 17D , including any alternative embodiments.

The flexible container  1700 - d  is the same as the flexible container  1700 - a  of  FIG. 17A , with like-numbered elements configured in the same way, except as described below. The flexible container  1700 - d  includes a product space  1750 - d  that is fully visible in  FIG. 17E  through a product viewing portion  1782 - e . The product viewing portion  1782 - e  is made from a flexible material that is transparent. The product viewing portion  1782 - e  is bounded on its top, bottom, and sides by an outer extent of a panel  1780 - e . The product viewing portion  1782 - e  extends continuously longitudinally, from a top portion of the panel  1780 - e  to a bottom portion of the panel  1780 - e  and from a left portion of the panel  1780 - e  to a right portion of the panel  1780 - e ; however, in various embodiments an product viewing portion may be discontinuous (e.g may include one or more opaque portions) or may only extend over part, parts, or all of a product space or a panel overlaying a product space in any convenient arrangement. In the embodiment of  FIG. 17E , the fill line  1754 - e  is visible through a top portion of the product viewing portion  1782 - e , from outside of the flexible container  1700 - e . So, a fill height for the fluent product  1751 - e  can be seen in the product viewing portion  1782 - e  when the product space  1750 - e  of the flexible container  1700 - e  is filled. And, since the product viewing portion  1782 - e  extends continuously from top to bottom, the product viewing portion  1782 - e  allows the fluent product  1751 - e  in the product space  1750 - e  to be seen at a number of locations; a fill height for the fluent product  1751 - e  can also be seen at any fill height as the flexible container  1750 - e  is emptied. Any embodiment of a flexible container disclosed herein can include a product viewing portion  1782 - e  as described and illustrated in connection with flexible container  1700 - e  of  FIG. 17E , including any alternative embodiments. 
       FIG. 18  is a flowchart illustrating a process  1890  of how a product with a flexible container is made, supplied, and used. The process  1890  begins with receiving  1891  materials, then continues with the making  1892  of the product, followed by supplying  1896  the product, and finally ends with using  1897  the product. 
     The receiving  1891  of materials can include receiving any materials and/or ingredients for making the product (e.g. ingredients for making a fluent product) and/or the container for the product (e.g. flexible materials to be converted into a flexible container). The flexible materials can be any kind of suitable flexible material, as disclosed herein and/or as known in the art of flexible containers and/or in U.S. non-provisional application Ser. No. 13/889,061 filed May 7, 2013, entitled “Flexible Materials for Flexible Containers” published as US20130337244 and/or in U.S. non-provisional application Ser. No. 13/889,090 filed May 7, 2013, entitled “Flexible Materials for Flexible Containers” published as US20130294711, each of which is hereby incorporated by reference. 
     The making  1892  includes the processes of converting  1893 , filling  1894 , and packaging  1895 . The converting  1893  process is the process for transforming one or more flexible materials and/or components, from the receiving  1891 , into a flexible container, as described herein. The converting  1893  process includes the further processes of unwinding  1893 - 1 , sealing  1893 - 2 , and folding  1893 - 3  the flexible materials then (optionally) singulating  1893 - 4  the flexible materials into individual flexible containers. The filling process  1894  includes the further processes of filling  1894 - 1  one or more product spaces of the individual flexible containers, from the converting  1893 , with one or more fluent products, expanding  1894 - 2  one or more structural support volumes with one or more expansion materials, then sealing  1894 - 3  the one or structural support frames and sealing  1894 - 3  and/or closing  1894 - 4  the one or more product spaces. The packaging  1895  process includes placing the filled product with a flexible container, from the filling  1894 , into one or more packages (e.g. cartons, cases, shippers, etc.) as known in the art of packaging. In various embodiments of the process  1890 , the packaging  1895  process may be omitted. In various embodiments, the processes of making  1892  can be performed in various orders, and additional/alternate processes for making flexible containers can be performed. 
     Any of the making  1892  processes can be accomplished according to any of the embodiments described here and/or as known in the art of making flexible containers and/or in U.S. non-provisional application Ser. No. 13/957,158 filed Aug. 1, 2013, entitled “Methods of Making Flexible Containers” published as US20140033654 and/or in U.S. non-provisional application Ser. No. 13/957,187 filed Aug. 1, 2013, entitled “Methods of Making Flexible Containers” published as US20140033655 and/or in U.S. provisional application 61/861,118 filed Aug. 1, 2013, entitled “Methods of Forming a Flexible Container” and/or in U.S. provisional application 61/900,450 filed Nov. 6, 2013, entitled “Flexible Containers and Methods of Forming the Same” and/or in U.S. provisional application 61/900,794 filed Nov. 6, 2013, entitled “Flexible Containers and Methods of Forming the Same” and/or in U.S. provisional application 61/900,805 filed Nov. 6, 2013, entitled “Flexible Containers and Methods of Making the Same” and/or in U.S. provisional application 61/900,810 filed Nov. 6, 2013, entitled “Flexible Containers and Methods of Making the Same,” each of which is hereby incorporated by reference. 
     In a line-up of flexible containers, according to any of the embodiments disclosed herein, both or all of the flexible containers in the line-up can be made with a common folding pattern and/or a common sealing pattern, such that both or all of the flexible containers in the line-up can be made on the same machine for making  1892  (e.g. converting  1893 , and/or filling  1894 , and/or packaging  1895 ) and/or packaging  1895 , as described in connection with embodiments of  FIG. 18 . As an example, a first flexible container in a line-up can be made using a particular model of a machine, while at the same time a second flexible container in the line-up can be made using the same particular model of the machine, but a different machine unit, according to embodiments disclosed herein. As another example, a first flexible container in a line-up can be made on a particular machine unit at a first time, and a second flexible container in the line-up can be made using the same particular machine unit at a second time that differs from the first time, according to embodiments disclosed herein. 
     A machine for making  1892  a flexible container, as described in connection with embodiments of  FIG. 18 , can include a particular set of unit operations for sealing (e.g. sealing  1893 - 2 ) flexible materials with a particular sealing pattern, resulting in a flexible container with a particular sealed configuration, as described herein. In any of the embodiments for a line-up of flexible containers, as described herein, the making of a first flexible container in the line-up and the making of the second flexible container in the line-up can use some or all of the same particular set of unit operations for sealing. By doing so, the same particular model of the machine, or even the same machine unit, can be used to make both a sealing pattern for the first flexible container and a sealing pattern for the second flexible container. As a result, the machine can switch from sealing the flexible container to sealing the second flexible container (or vice versa) without adding or removing any of the unit operations for sealing. In some embodiments, the machine can make such switches without changing parts in any of the unit operations for sealing. In other embodiments, the machine can make such switches without mechanically adjusting any of the unit operations for sealing. 
     A machine for making  1892  a flexible container, as described in connection with embodiments of  FIG. 18 , can include a particular set of unit operations for folding (e.g. folding  1893 - 3 ) flexible materials with a particular folding pattern, resulting in a flexible container with a particular folded configuration, as described herein. In any of the embodiments for a line-up of flexible containers, as described herein, the making of a first flexible container in the line-up and the making of the second flexible container in the line-up can use some or all of the same particular set of unit operations for folding. By doing so, the same particular model of the machine, or even the same machine unit, can be used to make both a folding pattern for the first flexible container and a folding pattern for the second flexible container. As a result, the machine can switch from folding the flexible container to folding the second flexible container (or vice versa) without adding or removing any of the unit operations for folding. In some embodiments, the machine can make such switches without changing parts in any of the unit operations for folding. In other embodiments, the machine can make such switches without mechanically adjusting any of the unit operations for folding. 
     In a line-up of flexible containers, according to any of the embodiments disclosed herein, the making (e.g. making  1892  of  FIG. 18 ), of both or all of the flexible containers in the line-up can include an expanding (e.g. expanding  1894 - 2  of  FIG. 18 ) of one or more structural support volumes with predetermined volumes and/pressures of one or more expansion materials, in various ways, as described below. 
     In a line-up of flexible containers, according to any of the embodiments described herein, a first flexible container can have a first predetermined volume of a first expansion material sealed inside, while a second disposable flexible container can have a second predetermined volume of a second expansion material (which can be similar to, the same as, or different from the first expansion material) sealed inside, wherein the second predetermined volume is greater than the first predetermined volume. For example, the first flexible container can have the first predetermined volume of the first expansion material sealed inside one or more first structural support volumes, such as structural support volumes that form the first structural support frame for the first container, while the second disposable flexible container can have the second predetermined volume of the second expansion material sealed inside one or more second structural support volumes, such as structural support volumes that form a second structural support frame for the second container. In various embodiments, the second predetermined volume can be 10-1000% more than the first predetermined volume, or any integer value for percentage from 10-1000%, or within any range formed by any of these values, such as 20-500%, 30-100%, etc. 
     In a line-up of flexible containers, according to any of the embodiments described herein, a first flexible container can have a first expansion material sealed inside at a first internal expansion pressure, while a second disposable flexible container can have a second expansion material sealed inside at a second internal expansion pressure, wherein the second internal expansion pressure is within 85% of the first internal pressure, or any integer value for percentage from 0-85%, or within any range formed by any of these values, such as 0-50%, 0-20%, etc. 
     A relatively different volume and/or pressure of expansion material(s) can be added to a structural support volume of a structural support frame of a flexible container in various ways, such as changing a flow rate when adding expansion material(s), and/or changing a time for adding expansion material(s), and/or changing a pressure at which expansion material(s) are added, and/or using an additional/alternate nozzle/dispenser for adding expansion material(s), and/or adding different expansion material(s) that expand at different rates or to different volumes, and/or changing an ability of expansion material(s) to escape before sealing the structural support frame, and/or sealing the structural support frame at a different sealing time after adding expansion materials, and/or sealing the structural support frame at a different sealing rate after adding expansion materials, and/or changing a size and/or shape of one or more structural support volumes in the structural support frame, etc. To make a flexible container that contains a particular predetermined volume and/or pressure of expansion material(s), one skilled in the art can empirically determine a target volume and/or pressure for the expansion material(s), in expanded form, within a flexible container, and then vary one or more of the conditions mentioned above, in the process of making the flexible container, to obtain the target volume and/or pressure. 
     The supplying  1896  of the product includes transferring the product, from the making  1892 , to product purchasers and/or ultimately to product users, as known in the art of supplying. The using  1897  of the product includes the processes of storing  1897 - 1 , handling  1897 - 2 , dispensing  1897 - 3 , and disposing  1897 - 4  of the product, as described herein and is known in the art of using products with flexible containers. Part, parts, or all of the process  1890  can be used to make products with flexible containers of the present disclosure, including products with line-ups of flexible containers. 
       FIG. 19  is a plan view of an exemplary blank  1900 - b  of flexible materials used to make a flexible container with a structural support frame, according to embodiments disclosed herein. A sealing pattern  1920  and a folding pattern  1940  are illustrated in relation to the blank  1900 - b . The blank  1900 - b  is formed by a first shaped cutout  1929 - b   1  and a second shaped cutout  1929 - b   2 , although in various embodiments, a blank may be formed by only one, or more than two shaped cutouts. The first shaped cutout  1929 - b   1  is made from a first sealable flexible material and the second shaped cutout  1929 - b   2  is made from a second sealable flexible material, which may be the same as or different from the first sealable flexible material. The first shaped cutout  1929 - b   1  and the second shaped cutout  1929 - b   2  have the same overall cutout shape, although in various embodiments shaped cutouts may have different shapes. The first shaped cutout  1929 - b   1  fully overlays and aligns with the second shaped cutout  1929 - b   2 , although in various embodiments a blank may have shaped cutouts that only partially overlay each other or only partially align. The first shaped cutout  1929 - b   1  is not initially attached to the second shaped cutout  1929 - b   2 , although in various embodiments, part or parts of one shaped cutout in a blank may be attached to one or more other shaped cutouts in the blank. The blank  1900 - b  is sealed according to the folding pattern  1920  and folded according to the folding pattern  1940 , to make a flexible container with a structural support frame, according to embodiments of the present disclosure. 
     The folding pattern  1920  includes a first set of seals  1929 - 1 , a second set of seals  1929 - 2 , and a third set of seals  1929 - 3 , which are illustrated in  FIG. 19  as dashed lines of varying dash length. While the first shaped cutout  1929 - b   1  fully overlays and aligns with the second shaped cutout  1929 - b   2 , the blank  1900 - b  is sealed with continuous seals along the dashed lines of the first set of seals  1929 - 2 . The first set of seals  1929 - 1  is represented by the dashed lines having a longest dash length in  FIG. 19 . 
     The first set of seals  1929 - 1  includes: the pair of mirrored trapezoidal shapes that are offset from the edges of the blank  1900 - b , on the left and right sides; two pairs of linear segments that extend along central parts of the top and bottom edges of the blank  1900 - b , on its left and right sides; and one linear segment that extends along the right side edge of the blank  1900 - b . The first set of seals  1929 - 1  seals through both the first shaped cutout  1929 - b   1  and the second shaped cutout  1929 - b   2 . 
     The sealing of the mirrored trapezoidal shapes from the first set of seals  1929 - 1  forms nonstructural panels for a product space of the flexible container being made from the blank  1900 - b . As a result, for the flexible container being made from the blank  1900 - b , the product space construction is based, at least in part on the sealing pattern  1920 . In particular, for the flexible container being made from the blank  1900 - b , substantially all of the product space construction is based on the first set of seals  1929 - 1  in the sealing pattern  1920 . In various embodiments, all of a product space construction can be based on a particular sealing pattern. 
     The sealing of the mirrored trapezoidal shapes from the first set of seals  1929 - 1  also forms inner portions of the structural support frame in the flexible container being made from the blank  1900 - b . The sealing of the linear segments from the first set of seals  1929 - 1  forms outer portions of the structural support frame for the flexible container being made from the blank  1900 - b.    
     After the blank  1900 - b  is sealed along the dashed lines of the first set of seals  1929 - 1 , the blank  1900 - b  is folded according to the folding pattern  1940 . The folding pattern  1940  includes a full fold at the fold line  1941 , although in various embodiments, a folding line can include partial and/or full folds along any number of folding lines. The fold line  1941  extends continuously from the top edge of the blank  1900 - b  to the bottom edge of the blank  1900 - b , although in various embodiments a fold line may be discontinuous or may extend over only part of a blank  1900 - b.    
     The blank  1900 - b  is folded at the fold line  1941  so that the portions of the first shaped cutout  1929 - b   1  and the second shaped cutout  1929 - b   2  on the right side fully overlay and align with the portions of the first shaped cutout  1929 - b   1  and the second shaped cutout  1929 - b   2  on the left side. The folding of the blank  1900 - b  along the fold line  1941  further forms a top, a bottom, and sides of the flexible container being made from the blank  1900 - b , wherein the narrow, open edge opposite the fold line  1941  is the partially formed top, the wide, folded edge adjacent the fold line  1941  is the partially formed bottom, and the angled, open, top and bottom edges are the partially formed sides. As a result, for the flexible container being made from the blank  1900 - b , the container construction is based, at least in part on the folding pattern  1940 . In particular, for the flexible container being made from the blank  1900 - b , the container construction is based on the fold line  1941  of the folding pattern  1940 . In various embodiments, substantially all or all of a container construction can be based on a particular folding pattern. 
     The folding of the blank  1900 - b  along the fold line  1941  also further forms the product space of the flexible container by bringing the nonstructural panels into positions that will be on a front and a back of the flexible container being made from the blank  1900 - b . As a result, for the flexible container being made from the blank  1900 - b , the product space construction is based, at least in part on the folding pattern  1940 . In particular, for the flexible container being made from the blank  1900 - b , the product space construction is based on the fold line  1941  of the folding pattern  1940 . In various embodiments, substantially all or all of a product space construction can be based on a particular folding pattern. 
     After the blank  1900 - b  is folded according to the folding pattern  1940  and while the blank  1900 - b  is maintained in this folded state, the blank  1900 - b  is sealed with continuous seals along the dashed lines of the second set of seals  1929 - 2 . The second set of seals  1929 - 2  is represented by the dashed lines having an intermediate dash length in  FIG. 19 . 
     The second set of seals  1929 - 2  includes: one pair of linear segments that extend along significant portions of the top and bottom edges of the blank  1900 - b , on its left side, including portions that extend next to and along portions of the first set of seals  192 - 1 . Since the second set of seals  1929 - 2  is made while the blank  1900 - b  is folded, the second set of seals  1929 - 2  seals through the left side of the second shaped cutout  1929 - b   2 , the left side and the (original) right side of the first shaped cutout  1929 - b    1 , and the (original) right side of the second shaped cutout  1929 - b   2 . The sealing of the linear segments from the second set of seals  1929 - 2  forms outer portions of the structural support frame for the flexible container being made from the blank  1900 - b . The sealing of the linear segments from the second set of seals  1929 - 2  also forms an outer extent of the product space of the flexible container being made from the blank  1900 - b.    
     Before the structural support frame is fully sealed, one or more expansion materials can be added to the partially formed structural support frame, as described herein. And, before the product space is fully closed and/or sealed, one or more fluent products can be added to the partially formed product space, as described herein. 
     After the blank  1900 - b  is sealed along the dashed lines of the second set of seals  1929 - 2  and while the blank  1900 - b  remains in the folded and partially sealed state, the blank  1900 - b  is sealed with continuous seals along the dashed lines of the third set of seals  1929 - 3 . The third set of seals  1929 - 3  is represented by the dashed lines having a shortest dash length in  FIG. 19 . 
     The third set of seals  1929 - 2  includes: one pair of linear segments that extend in parallel from the left side edge of the blank  1900 - b , inward to the trapezoidal shape; a first three sided shape, having a first side extending from the upper parallel segment, along an upper portion of the left side edge of the blank  1900 - b , a second side extending along an outer portion of the top edge of the blank  1900 - b , and a third side extending from the top edge of the blank  1900 - b  back to the upper parallel segment; a second three sided shape, having a first side extending from the lower parallel segment, along a lower portion of the left side edge of the blank  1900 - b , a second side extending along an outer portion of the bottom edge of the blank  1900 - b , and a third side extending from the bottom edge of the blank  1900 - b  back to the lower parallel segment; and, a pair of linear segments that extend next to and along outer portions of the trapezoidal shape from the first set of seals  192 - 1 . 
     Since the third set of seals  1929 - 3  is made while the blank  1900 - b  is folded, the third set of seals  1929 - 3  seals through the left side of the second shaped cutout  1929 - b   2 , the left side and the (original) right side of the first shaped cutout  1929 - b   1 , and the (original) right side of the second shaped cutout  1929 - b   2 . The sealing of the parallel linear segments from the third set of seals  1929 - 3  forms a product dispensing path in the flexible container being made from the blank  1900 - b ; the product dispensing path can be closed and/or sealed with any kind of suitable closure, seal, or dispenser disclosed herein or known in the art. The sealing of the other linear segments from the third set of seals  1929 - 3  forms portions of the top of the flexible container being made from the blank  1900 - b , and also fully seals the structural support frame of the flexible container being made from the blank  1900 - b.    
     In a line-up of flexible containers, according to any of the embodiments disclosed herein, both or all of the flexible containers in the line-up can include one or more product spaces, each product space having a product space construction, and any of the product space constructions can be partly, substantially, or fully based on part, parts, or all of one or more common folding patterns and/or can be partly, substantially, or fully based on part, parts, or all of one or more common sealing patterns.

The intermediate bottom structural support volume  2048 - 3  is disposed in a bottom central part of the container between a front bottom structural support volume and a back bottom structural support volume. 
     The middle structural support volume  2046 - 1  is made from portions of two layers of film and the first reinforcing seal  2027 - 1  extends through other portions of those two layers of film, but not through any additional layers of film of the container  2000 . The middle structural support volume  2046 - 4  is made from portions of two layers of film and the second reinforcing seal  2027 - 2  extends through other portions of those two layers of film, but not through any additional layers of film of the container  2000 . The intermediate bottom structural support volume  2048 - 3  is made from portions of two layers of film and the third reinforcing seal  2027 - 3  extends through other portions of those two layers of film, but not through any additional layers of film of the container  2000 . In various embodiments, any of these layers may be separate layers of material, may be joined and/or connected to each other, and/or may be separate portions of larger sheets; any of these layers can be a single layer of film, a single layer of flexible material, a layer that is a laminate made from multiple films, or a laminate made from multiple flexible materials, in any form described herein or known in the art. 
     The upper main seal  2029  extends through portions of the two layers of film that make the middle structural support volume  2046 - 1  and also through portions of the two layers of film that make the middle structural support volume  2046 - 4 . The first lower main seal  2029 - 1  extends through portions of the two layers of film that make the middle structural support volume  2046 - 1  and also through portions of the two layers of film that make the intermediate bottom structural support volume  2048 - 3 . The second lower main seal  2029 - 2  extends through portions of the two layers of film that make the middle structural support volume  2046 - 4  and also through portions of the two layers of film that make the intermediate bottom structural support volume  2048 - 3 . 
     A main seal has an overall thickness based on the combined thickness of the layers of film through which it extends. As an example, a main seal can have an overall thickness of 160-800 mil, or any integer value between 160 and 800 mil, or any range formed by any of these values, such as 300-500 mil, etc. 
     The upper main seal  2029 , the first lower main seal  2029 - 1 , and the second lower main seal  2029 - 2 , are outwardly projecting fin seals; however, this is not required, and part, parts, or all of any of these seals can be configured in any other way disclosed herein or known in the art. At least a portion of the upper main seal  2029  is disposed along a longitudinal centerline of the container. 
     As the upper main seal  2029  travels downward, its right two layers join an upper portion of the first lower main seal  2029 - 1  and turn to the right while its left two layers join an upper portion of the second lower main seal  2029 - 2  and turn to the left. For the two layers of film that make the intermediate bottom structural support volume  2048 - 3 , on the right, right portions of these the two layers form the lower portion of the first lower main seal  2029 - 1 , while, on the left, left portions of these the two layers form the lower portion of the second lower main seal  2029 - 2 . 
     The intersection of the upper main seal  2029  with the first lower main seal  2029 - 1  forms a first interior vertex  2026 - 1  of a main seal that is formed and effectively angled by the intersecting portions of the upper main seal  2029  and the first lower main seal  2029 - 1 , with a first effective angle  2027 - 1   a , which is an obtuse angle, but can, in various embodiments, be a right angle or an acute angle. The intersection of the upper main seal  2029  with the second lower main seal  2029 - 2  forms a second interior vertex  2026 - 2  of a main seal that is formed and effectively angled by the intersecting portions of the upper main seal  2029  and the second lower main seal  2029 - 2 , with a second effective angle  2027 - 2   a , which is an obtuse angle, but can, in various embodiments, be a right angle or an acute angle. The intersection of the first lower main seal  2029 - 1  with the second lower main seal  2029 - 2  forms a third interior vertex  2026 - 3  of a main seal that is formed and effectively angled by the intersecting portions of the first lower main seal  2029 - 1  and the second lower main seal  2029 - 2 , with a third effective angle  2027 - 3   a , which is an acute angle, but can, in various embodiments, be a right angle or an obtuse angle. 
     While the structure of seals described above is generally well-designed, the intersections between the seals tend to form stress concentrations. The elevated internal pressure(s) in the expanded structural support volumes can add further stresses to this sealed structure. In any flexible container of the present disclosure, any or all of the expanded structural support volumes can have an internal pressure of 25-100 kiloPascals, or any integer value for kiloPascals between 25 and 100, or any range formed by any of these values, such as 35-85 kiloPascals, 45-70 kiloPascals, etc. Structural support volumes with larger diameters tend to create more stresses on their adjacent seals. In any flexible container of the present disclosure, any or all of the expanded structural support volumes can have a largest overall cross-sectional dimension of 20-65 millimeters, or any integer value for millimeters between 20 and 65, or any range formed by any of these values, such as 25-55 millimeters, 30-45 millimeters, etc. As a result of these conditions, without targeted reinforcement, seals in this structure can be prone to failure, which can lead to depressurization of one or more of the structural support volumes; this can cause the structural support frame  2040  to partially or fully deflate, so that it no longer effectively supports the product volume of the container. So, one or more reinforcing seals within this structure can be useful to strengthen the intersections and/or angles of one or more main seals, to prevent such failures. 
     An upper portion of the first reinforcing seal  2027 - 1  is disposed between and immediately adjacent to a portion of the middle structural support volume  2046 - 1  as well as a portion of the upper main seal  2029 . A lower portion of the first reinforcing seal  2027 - 1  is disposed between and immediately adjacent to a portion of the middle structural support volume  2046 - 1  as well as a portion of the first lower main seal  2029 - 1 . An upper portion of the second reinforcing seal  2027 - 2  is disposed between and immediately adjacent to a portion of the middle structural support volume  2046 - 4  as well as a portion of the upper main seal  2029 . A lower portion of the second reinforcing seal  2027 - 2  is disposed between a portion of the middle structural support volume  2046 - 4  and a portion of the second lower main seal  2029 - 2 . A left portion of the third reinforcing seal  2027 - 3  is disposed between a portion of the intermediate bottom structural support volume  2048 - 3  and a portion of the second lower main seal  2029 - 2 . A right portion of the third reinforcing seal  2027 - 1  is disposed between a portion of the intermediate bottom structural support volume  2048 - 3  and a portion of the first lower main seal  2029 - 1 . 
     The first reinforcing seal  2027 - 1  is disposed proximate to the first interior vertex  2026 - 1  and extends through portions of the two layers of film that make the middle structural support volume  2046 - 1  but not through any portion of the two layers of film that make the middle structural support volume  2046 - 4  and not through any portion of the two layers of film that make the intermediate bottom structural support member  2048 - 3 . The first reinforcing seal  2027 - 1  is bounded by a lower portion of the upper main seal  2029 , an upper portion of the first lower main seal  2029 - 1 , and, on the side of the middle structural support volume  2046 - 1 , by an outer edge  2028 - 1  that extends from the upper main seal  2029  to the first lower main seal  2029 - 1 . All of the outer edge  2028 - 1  is substantially linear, however, in various embodiments, part, parts, or all of an outer edge can be linear, curved inward, curved outward, or combinations of any of these. As a result, the reinforcing seal  2027 - 1  has an overall shape that is substantially triangular. 
     The second reinforcing seal  2027 - 2  is disposed proximate to the second interior vertex  2026 - 2  and extends through portions of the two layers of film that make the middle structural support volume  2046 - 4  but not through any portion of the two layers of film that make the middle structural support volume  2046 - 1  and not through any portion of the two layers of film that make the intermediate bottom structural support member  2048 - 3 . The second reinforcing seal  2027 - 2  is bounded by a lower portion of the upper main seal  2029 , an upper portion of the second lower main seal  2029 - 2 , and, on the side of the middle structural support volume  2046 - 4 , by an outer edge  2028 - 2  that extends from the upper main seal  2029  to the second lower main seal  2029 - 2 . All of the outer edge  2028 - 2  is substantially linear. As a result, the reinforcing seal  2027 - 2  has an overall shape that is substantially triangular. 
     The third reinforcing seal  2027 - 3  is disposed proximate to the third interior vertex  2026 - 3  and extends through portions of the two layers of film that make the intermediate bottom structural support member  2048 - 3  but not through any portion of the two layers of film that make the middle structural support volume  2046 - 1  and not through any portion of the two layers of film that make the middle structural support volume  2046 - 4 . The third reinforcing seal  2027 - 3  is bounded by an upper portion of the first lower main seal  2029 - 1 , an upper portion of the second lower main seal  2029 - 2 , and, on the side of the intermediate bottom structural support volume  2048 - 3 , by an outer edge  2028 - 3  that extends from the first lower main seal  2029 - 1  to the second lower main seal  2029 - 2 . All of the outer edge  2028 - 2  is substantially curved with a curve that is concave with respect to the intermediate bottom structural support volume  2048 - 3 . As a result, the third reinforcing seal  2027 - 3  has an overall shape that is substantially like a boomerang. 
     A reinforcing seal can have various sizes. A reinforcing seal can have a widest overall width of 2-20 millimeters, or any integer value between 2 and 20 millimeters, or any range formed by any of these values, such as 3-15 millimeters, 4-10 millimeters, etc. For a reinforcing seal disposed proximate to one or more main seals angled or effectively angled to form an interior vertex, the widest width is measured linearly across the surface of the reinforcing seal from the interior vertex, along a bisecting reference line, to its outer edge. For a reinforcing seal that is disposed proximate to one or more main seals that are not angled or effectively angled to form an interior vertex, the widest width is measured as the largest linear distance across the surface of the reinforcing seal, from the main seal, measured perpendicular to the main seal, to an outer extent of the reinforcing seal. The first reinforcing seal  2027 - 1  has a widest overall width  2027 - 1   w , the second reinforcing seal  2027 - 2  has a widest overall width  2027 - 2   w , and the third reinforcing seal  2027 - 3  has a widest overall width  2027 - 3   w.    
     A reinforcing seal can have a longest overall length of 2-250 millimeters, or any integer value between 2 and 250 millimeters, or any range formed by any of these values, such as 3-100 millimeters, 4-50 millimeters, etc. For any reinforcing seal (having an outer edge that is linear, non-linear, or any combination of these), the longest overall length of the reinforcing seal is measured linearly from one end of its outer edge to the other end of its outer edge. The first reinforcing seal  2027 - 1  has a longest overall length  2027 - 11 , the second reinforcing seal  2027 - 2  has a longest overall length  2027 - 21 , and the third reinforcing seal  2027 - 3  has a longest overall length  2027 - 31 . 
     A reinforcing seal has an overall thickness based on the combined thickness of the layers of film through which it extends. As an example, a reinforcing seal can have an overall thickness of 80-400 mil, or any integer value between 100 and 300 mil, or any range formed by any of these values, such as 150-250 mil, etc. 
     In the embodiment of  FIG. 21A , the reinforcing seals align in particular ways, as described below. An upper portion of the first reinforcing  2027 - 1  seal is disposed on the right side of the upper main seal  2029 , and an upper portion of the second reinforcing seal  2027 - 2  is disposed directly opposite, on the left side of the upper main seal  2029 . A lower portion of the second reinforcing  2027 - 2  seal is disposed on the upper left side of the second lower main seal  2029 - 2 , and a left portion of the third reinforcing seal  2027 - 3  is disposed directly opposite, on the lower right side of the second lower main seal  2029 - 2 . A right portion of the third reinforcing  2027 - 3  seal is disposed on the lower left side of the first lower main seal  2029 - 1 , and a lower portion of the first reinforcing seal  2027 - 1  is disposed directly opposite, on the upper right side of the first lower main seal  2029 - 1 . However, in various embodiments, such alignments of reinforcing seals are not required. 
     In the embodiment of  FIG. 21A , the ends of the outer edges of the reinforcing seals align in particular ways, as described below. The upper left end of the outer edge  2028 - 1  of the first reinforcing  2027 - 1  seal aligns with the upper right end of the outer edge  2028 - 2  of the second reinforcing seal  2027 - 2 , at a point on the upper main seal  2029 . A lower left end of the outer edge  2028 - 2  of the second reinforcing  2027 - 2  seal aligns with the left end of the outer edge  2028 - 3  of the third reinforcing seal  2027 - 3 , at a point on the second lower main seal  2029 - 2 . A right end of the outer edge  2028 - 3  of the third reinforcing seal  2027 - 3  aligns with the lower right end of the outer edge  2028 - 1  of the first reinforcing seal  2027 - 1 , at a point on the first lower main seal  2029 - 1 . However, in various embodiments, such alignments of outer edges of reinforcing seals are not required. 
     While the reinforcing seals illustrated in  FIG. 21A  are illustrated with respect to the intersection of three main seals, which are fin seals, such reinforcing seals can be applied to turns, angles, and/or curves of a single main seal (without any intersection), and/or applied to an intersection of any number of main seals (such as four, five, or more), and/or applied to any kind of seal known in the art (for sealing two or more flexible materials together). 
       FIG. 21B  illustrates an even closer view of  FIG. 21A , which shows portions of the four layers of film in the upper main seal  2029  and portions of the two layers of film in the first reinforcing seal  2027 - 1 . 
     The upper main seal  2029  extends through portions of the two layers of film  2029 - c  and  2029 - d  that make the middle structural support volume  2046 - 4  and also through portions of the two layers of film  2029 - a  and  2029 - b  that make the middle structural support volume  2046 - 1 . The first reinforcing seal  2027 - 1  extends through portions of the two layers of film  2029 - a  and  2029 - b , which are sealed together, but are shown broken away as inner and outer parts, to illustrate their layered relationship and to reveal the product volume  2050  behind them. The middle structural support volume  2046 - 1  is made from different portions of these two layers of film  2029 - a  and  2029 - b , which are sealed together with spaced apart seals, but are shown broken away in first and second parts, to reveal: first, an expanded space  2046 - 1   es  in the middle structural support volume  2046 - 1  that exists between the outer layer of film  2029 - a  and the inner layer of film  2029 - b ; and, second the product volume  2050  behind the inner layer of film  2029 - b.
