Title: Easy open and reclosable package with discrete laminate with die-cut

Description:
FIELD OF THE INVENTION 
     This invention relates to an easy-open and reclosable package with a discrete laminate with a die-cut, and to methods of making the package. 
     BACKGROUND OF THE INVENTION 
     Food and non-food products, including produce, snack foods, cheese and the like have long been packaged in containers such as pouches, bags, or lidded trays or formed webs made from various thermoplastic materials such as polyethylene, polypropylene, or polyester (PET). These containers can be formed from a web or webs of thermoplastic material on packaging equipment, using various packaging processes, at a processing/packaging facility. Such equipment and processes includes horizontal form/fill/seal (HFFS), vertical form/fill/seal (VFFS), thermoforming/lidstock, and continuous horizontal packaging (sometimes referred to as Flow-wrap). In each case, the product is manually or automatically placed in a pouch, bag, formed web, tray, etc., the filled container is optionally vacuumized or gas flushed, and the mouth of the container is hermetically or non-hermetically sealed to close and finish the package. 
     Opening of the finished package (i.e. opening with the use of tools such as scissors or knives) can provide access to the product by the consumer. 
     Common in the industry is the use of plastic zipper closures; press-to-close or slide zippers; interlocking closures; reclosable fasteners with interlockable fastener elements; interlocking rib and groove elements having male and female profiles; interlocking alternating hook-shaped closure members, and the like. These terms appear in the patent literature, and to some extent may overlap in meaning. These features provide reclosability, and in some cases may provide an easy-open feature to the package. However, such features are not always easy to open or reclose. 
     Also relatively common is the use of pressure sensitive adhesive to provide a reclosability feature to a package. However, depending on the position of the adhesive relative to the package, the adhesive can sometimes be contaminated by the contained product before the package is opened, or once the package is opened, when product is removed from the package and comes in contact with the adhesive. This phenomenon can compromise the reclosability of the package. 
     There is need in the marketplace for a package, and methods of packaging that can be used in a manner that requires little or no modification to the packager&#39;s packaging equipment, while providing a manually (i.e. by hand, without the need for tools such as scissors or knives) openable and easy to reclose feature, optionally while maintaining hermeticity of the package when made, and without the use of plastic zipper closures; press-to-close or slide zippers; interlocking closures; reclosable fasteners with interlockable fastener elements; interlocking rib and groove elements having male and female profiles; interlocking alternating hook-shaped closure members, and the like. 
     Some retail packages currently do not offer an easy-open and/or reclosable feature. Examples are some produce bags and snack food bags. In the produce market, there is a need for a cost-effective way to manually open, and repeatably reclose, retail produce bags, e.g. a package made in HFFS, VFFS, thermoforming/lidstock, or continuous horizontal packaging processes. 
     The present invention relates to a package, and methods of making the package, which package is manually openable, and reclosable, i.e. can be opened and reclosed a number of times, and adapted to package non-food products, as well as food products such as e.g. produce, snack foods, cheese, luncheon meat, sausage, culinary nuts, trail mix, etc., as well as products for the medical industry. The package optionally maintains a hermetic seal until the package is opened. 
     There is also a need in the marketplace for a discrete laminate that can be anchored to a processor&#39;s packaging material of choice to provide easy-open and reclosable functionalities to a package made from that web/laminate combination with only relatively minor modifications to the processor&#39;s packaging material, packaging process or equipment.

     DEFINITIONS 
     “Anchored”, “anchoring” and the like herein refers to sealing or adhering two surfaces together, and refers to the resulting bond between surfaces. Sealing is done by means of a sealant. Adhering is done by means of permanent adhesive. 
     In processes described herein where a base strip or discrete laminate is anchored to a web, panel section or side panel, either during the process wherein the web and discrete laminate are advanced, or when a discrete laminate or component thereof has been pre-anchored to the web before the start of the process, anchoring can be done by use of any suitable continuous or discontinuous sealing or adhesive material and method. Such anchoring can be done to hold the discrete laminate or component thereof to the web, panel section or side panel during the relevant packaging process. 
     In some embodiments, wherein the anchor is already relatively strong or continuous, e.g. a heat seal that constitutes either a relatively strong heat seal, or an easy-open seal as defined herein, the anchor functions not only to hold the base strip to discrete laminate to the web or panel during the relevant packaging process, but also as a final seal of that surface of the strip or discrete laminate to the web (lay-flat or folded) panel section or panel made from the web. 
     Any subsequent disclosed or recited step in the process of sealing one of the surfaces (i.e. the anchored surface) of the base strip or discrete laminate to a web, panel section or panel, is already completed by the anchoring step. In these embodiments, then, contact of a seal device, e.g. a seal bar in the region of the anchor, in a subsequent step, may add no further or separate seal to that surface of the discrete laminate. 
     Any subsequent step in the process of sealing the other surface of the discrete laminate to a web, panel section or panel, then, may in some embodiments add no further or separate seal to the anchored surface of the discrete laminate. 
     In some embodiments where the bond is a relatively weak or discontinuous one, e.g. a discontinuous seal, spots or narrow stripes of adhesive. etc., in a subsequent step of sealing one of the surfaces of the base strip or discrete laminate to the web, panel section or panel, a seal bar that seals one of the surfaces of the strip or discrete laminate to the web, panel section or panel can contact the web, panel section or panel in the region where the anchor is already disposed. The seal in that region may be either enhanced, or initially created, by the subsequent sealing step. 
     Sealing of a surface of the strip or discrete laminate to a web, panel section or panel, as a process step disclosed or recited herein, should be understood in this light. 
     “Backing segment” refers to a monolayer or multilayer portion of a base strip that can be sealed to a web or second side panel by a sealant. 
     “Closed-loop” herein refers to a die cut that defines a closed pattern or path in the panel section whereby the web material within the path (the die-cut segment) can be removed from the panel. 
     “Die cut” herein refers to methods of cutting or scoring materials, including rotary die, steel rule die, platen die cutting, and laser cutting or scoring, and/or the resultant cut or score. A die cut can extend entirely or partially through the relevant layer or web, and can leave intact a certain amount of material. “Score” and the like herein refers to a partial die cut that extends partly but not entirely through the thickness of a material, layer, web, panel, panel section, etc, The purpose of the score in the present invention is to provide for controlled tear or separation of material in the act of displacing or removing the die cut segment. The depth of the cut can vary from package to package, and within a single die cut on a given package. 
     “Die-cut segment” herein refers to a portion of the panel section that can be displaced or completely removed because of the presence of a closed loop or open loop die cut. The die-cut segment is a piece of the panel section, and when displaced or removed can sometimes function as a tamper evidence device, and facilitates access to the interior of the package. 
     “Discrete” with respect to the discrete laminate is used herein to mean independently made (the discrete laminate is not an integral part of the web when the web is made,) or constituting a separate entity from the web, and from a first or second side panel made from the web. 
     “Easy-open” herein refers to a package that can be manually opened relatively easily. The physical mode of opening may include any one or more of a) actual peeling at the base strip/web interface (adhesive failure), or b) a sealant layer of the base strip breaking completely through, and peeling then occurring between the sealant layer and an adjacent layer within the strip (delamination failure), or c) breaking within a sealant layer by rupturing of the sealant material itself (cohesive failure). The peel force required to open the package can be measured by an evaluation of seal strength or peel strength in accordance with the test procedure set out in ASTM F88, incorporated herein by reference in its entirety, using a crosshead speed of 8 to 12 inches/minute and an initial jaw gap of from 1.00 inch to 2.00 inch. Typical peel forces for opening the package of the invention can range from e.g. 25 grams/inch to 3 pounds/inch, e.g. from 100 grams/inch to 2 pounds/inch, such as from 200 grams/inch to 1.5 pounds/inch. In some cases, the sealant may actually peel away from the surface to which it is adhered (adhesive failure), or breakage of the sealant and delamination along an adjacent layer interface may occur (delamination failure) or a rupture of the sealant can occur (cohesive failure). Depending on the design and geometry of the seal, peel forces can in some embodiments be higher than 3 pounds/inch, e.g. 3.5, 4.0, 4.5, or 5 pounds/inch, or values intermediate these values. When a die cut segment is displaced or removed from the panel section, such that the PSA is exposed, in some embodiments some part of the scored portion of the die cut segment that remains after the die cutting process, may be torn through in the act of opening the package. The peel force required for this step in the opening process will be within the parameters discussed herein. 
     “Easy-open seal” herein refers to a seal involving the base strip, panel section or web in which materials and sealing conditions are chosen for the base strip, panel section and web such that the package is easy-open with a physical mode of opening that includes one or more of adhesive failure, delamination failure, or cohesive failure as described herein. 
     “Easy-open sealant” herein refers to a material chosen for one or both surfaces of the base strip or panel section, such that when such surface is sealed to a web, it provides a package that is easy-open with a physical mode of opening that includes one or more of adhesive failure, delamination failure, or cohesive failure as described herein. 
     “Ethylene/alpha-olefin copolymer” (EAO) herein refers to copolymers of ethylene with one or more comonomers selected from C 3  to C 10  alpha-olefins such as propene, butene-1, hexene-1, octene-1, etc. EAO includes heterogeneous materials such as linear medium density polyethylene (LMDPE), linear low density polyethylene (LLDPE), and very low and ultra low density polyethylene (VLDPE and ULDPE); single-site catalyzed materials such as homogeneous linear ethylene/alpha olefin copolymers and long chain branched ethylene/alpha olefin copolymers; and multicomponent ethylene/alpha-olefin interpenetrating network resin (or “IPN resin”). 
     “Ethylene homopolymer or copolymer” herein refers to polyethylene (PE) such as ethylene homopolymer such as low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE); ethylene/alpha olefin copolymer such as those defined herein; ethylene/vinyl acetate copolymer (EVA); ethylene/alkyl acrylate copolymer such as ethylene/methyl acrylate copolymer (EMA) or ethylene/ethyl acrylate copolymer (EEA), or ethylene/butyl acrylate copolymer (EBA); ethylene/(meth)acrylic acid copolymer; or ionomer resin (IO). 
     “Fig.” and the like herein refers to a drawing figure; “Figs.” and the like herein to drawing figures. 
     “Film” is used herein to mean a thermoplastic film, laminate, or web, either multilayer or monolayer, that may be used in connection with the present invention. Film can be of any suitable thickness, e.g. between 0.1 and 30 mils. 
     “Fin seal” is used herein to mean, in the case of a single web, folding one edge of the web towards the opposite edge of the web, and sealing the facing inner surfaces together. In the case of two webs, a fin seal is a seal formed by sealing the inner surface of the edge of one web to the inner surface of a corresponding edge of another web. 
     “Lap seal” is used herein to mean a seal made by sealing an inside surface of a web to an outside surface of a web. The inside and outside surfaces can both be on a single web; or the inside surface can be of one web, and the outside surface of a second web. 
     “Lidstock” herein refers to a film used to cover a container or tray that carries a product, and can be sealed to the tray, typically as a perimeter heat seal. Lidstock typically is supplied to a food processor in a lay flat film rolled onto a roll. 
     “Longitudinal seal” herein refers to a fin seal or lap seal. 
     “Near” herein means, with respect to the position of the discrete laminate in relation to the package, that the first end  28  of the base strip of the discrete laminate closest to the first end of the pouch and package will be typically within about three inches of the first end of the pouch. The strip  10  can be closer than this, such as within about two inches, one and one quarter inches, one inch, 0.75 inches, 0.5, 0.4, 0.3, 0.2, or 0.1 inches of the first end of the pouch. 
     “Olefinic” and the like herein refers to a polymer or copolymer derived at least in part from an olefinic monomer. 
     “Open-loop” herein refers to a die cut that defines an open pattern or path in the panel section whereby the web material within the path or pattern (the die-cut segment) can be displaced from its original position on the panel section, e.g. by acting as a flap. 
     “Oxygen barrier” and the like herein refers to materials having an oxygen permeability, of the barrier material, less than 500 cm 3  O 2 /m 2 ·day·atmosphere (tested at 1 mil thick and at 25° C., 0% RH according to ASTM D3985), such as less than 100, less than 50, less than 25, less than 10, less than 5, and less than 1 cm 3  O 2 /m 2 ·day·atmosphere.

     “Polymer” and the like herein means a homopolymer, but also a copolymer thereof, including terpolymer, tetrapolymer, block copolymer, etc. 
     “Pouch” herein means a pouch or bag. 
     “Pressure sensitive adhesive” (PSA) herein refers to a repositionable adhesive that bonds firmly with the application of light pressure. It adheres to most surfaces with very slight pressure; is available in solvent and latex or water based forms, and is often based on non-crosslinked rubber adhesives, acrylics, or polyurethanes. PSA forms viscoelastic bonds that are aggressively and permanently tacky; adhere without the need for more than hand pressure; and require no activation by water, solvent, or heat. Some PSA materials are cured by hot air, electron beam, UV, or chemical (peroxide) means. They are available in a wide variety of chemical compositions and systems including acrylic and methacrylate adhesives, emulsion-based acrylic adhesive; rubber-based pressure sensitive adhesive, styrene copolymers (styrene/isoprene/styrene and styrene/butadiene/styrene block copolymers), and silicones. In some embodiments, hot melt adhesives may be useful as well, are included herein for those embodiments as “PSA”; a hot melt adhesive is a thermoplastic adhesive compound, usually solid at room temperature which becomes fluid on heating for use. Suitable commercial examples of PSA include PS-2000™ from Dow, and “acResin®”, available from BASF, and comprising a UV-curable polyacrylate that can be applied by conventional hot-melt coaters at temperatures of about 120° C. Suitable tackifiers can be added to acResin® or like compositions to control the tackiness of the adhesive; examples are FORAL® 85 synthetic resin available from Pinova. Tackifiers can be added to the discrete adhesive composition in any suitable amount, e.g. from 15% to 25% by weight of the total composition of PSA and tackifier. In some embodiments, the PSA can be blended with an olefinic additive such as polyethylene, ethylene/methyl acrylate copolymer, or ethylene/vinyl acetate copolymer. These blends can be in any suitable proportions of the PSA and olefinic additive, as long as the easy-open and reclosable functionality of the package is substantially maintained. Extrudable pressure sensitive hot melt adhesive, having an appropriate melt index and melt strength, can be extruded as an intermediate layer within a multilayer structure made by a blown or cast film process. This layer would impart the reclosable characteristics to the structure. Examples of extrudable PSA materials include but not limited to the M-series materials such as M3156T™ and M551™ available from Bostik; HL2942M™ available from H B Fuller; and VECTOR™ 4114A and 4186A available from Dexco. Alternatively, blends of these materials can be made with compatible materials that may act as processing aids, without unduly compromising the reclose characteristics of the original PSA. Extrudable adhesive chemistries include styrene-Isoprene-styrene and styrene-butadiene-styrene copolymers, including both the linear blocks (e.g. the resins from Bostik) and radial blocks (the VECTOR resins); silicones; high comonomer content EVA, EMA, EBA etc. based formulations; and INFUSE™ olefinic block copolymer based materials. Those skilled in the art will appreciate, after a review of this disclosure, that a particular PSA can be selected based at least in part on the particular process used to produce the film from which the discrete strip is made, e.g. coextrusion, extrusion coating, etc., and the appropriate rheology and process characteristics of the PSA desired for that process, while ensuring that the easy-open and reclosable features of the package made in accordance with the invention are substantially maintained. 
     “Reclosable” herein refers to a feature or function of a package in accordance with the invention whereby a package can be reclosed by bringing a folded web, panel, or panel section, or portion of a folded web, panel, or panel section into contact with the PSA of the base strip.

     DETAILED DESCRIPTION OF THE INVENTION 
     1. Package 
     Referring to the drawings, a package  5  according to the invention is shown. Package  5  includes a pouch  7  that can be made from either a single web, or two webs, to form a first side panel  12 , and a second side panel  14 . 
     A. Web(s) 
     In either embodiment, the web or webs comprises a thermoplastic material of any suitable composition, including those having as at least one component olefinic materials such as ethylene or propylene polymers or copolymers, e.g. polyethylene or ethylene/alpha olefin copolymers; polyethylene terephthalate (PET); and including webs typically used in, or useful in, HFFS, VFFS, lidstock/tray, continuous horizontal packaging, and bag making apparatus and processes. The web or webs can be monolayer or multilayer in construction, can be coextruded, laminated, or made by any suitable film making process, and can have any suitable thickness. 
     Examples of web(s) that can be used with a discrete laminate of the invention include H7225B™, a barrier hybrid material used for products requiring a high oxygen barrier, such as shredded cheese; H7525B™, a barrier hybrid material used for products requiring a high oxygen barrier, such as bacon and smoked and processed meat; H7530B, like H7525B but having a thickness of about 3 mils; CP04140™, a low barrier (high OTR) material used in produce packaging; CPM4090, a microwaveable packaging film for fresh cut produce; and T7225B™, a barrier material used as lidstock (non-forming web) for products requiring a high oxygen barrier, such as luncheon meat. These are all commercial products produced by the Cryovac business unit of Sealed Air Corporation. 
     H7225B™ is a laminate having the construction PET//adhesive//coextruded barrier film, where the PET is a biaxially oriented polyester film, and the barrier film has in one embodiment the construction LDPE (low density polyethylene)/EVA tie/nylon/EVOH+nylon/nylon/EVA tie/EAO. The overall thickness of the laminate of this construction can be any of several gauges, being typically about 2.5 mils. The LDPE is the surface of the barrier film adhered, by the adhesive, to the PET film. The EAO typically acts as the heat sealant layer of the film, and finished laminate, and in packaging made from the laminate, the EAO will form the inner or sealant surface of the package, facing the contained product, and the PET will form the outer or skin surface of the package. H7225B™ can be used as a lidstock (non-forming) web. 
     H7525B™ is a laminate having the construction PET//adhesive//coextruded barrier film, where the PET is a biaxially oriented polyester film, and the barrier film has in one embodiment the construction LDPE (low density polyethylene)/EVA/LLDPE tie/EVOH/LLDPE tie/EVA/EAO. The overall thickness of the laminate of this construction can be any of several gauges, being typically about 2.5 mils. The LDPE is the surface of the barrier film adhered, by the adhesive, to the PET film. The EAO typically acts as the heat sealant layer of the film, and finished laminate, and in packaging made from the laminate, the EAO will form the inner or sealant surface of the package, facing the contained product, and the PET will form the outer or skin surface of the package. H7525B™ can be used as a lidstock (non-forming) web. 
     CP4140™ is a laminate having the construction BOPP//adhesive/monolayer LLDPE film. A typical gauge for the laminate is about 1.8 mils. The LLDPE typically acts as the heat sealant layer of the finished laminate, and in packaging made from the laminate, the LLDPE will form the inner or sealant surface of the package, facing the contained product, and the BOPP will form the outer or skin surface of the package. 
     CPM4090™ is a laminate having the construction BOPP//adhesive/monolayer LLDPE+LDPE film. A typical gauge for the laminate is about 2 mils. The LLDPE+LDPE layer typically acts as the heat sealant layer of the finished laminate, and in packaging made from the laminate, the LLDPE+LDPE will form the inner or sealant surface of the package, facing the contained product, and the BOPP will form the outer or skin surface of the package. 
     T7225B™ film has the construction EAO/EAO/LLDPE tie/nylon/EVOH/nylon/EVA tie/EVA tie/nylon. The first layer of EAO typically acts as the heat sealant layer of the film, and in packaging made from the laminate, the EAO will form the inner or sealant surface of the package, facing the contained product, and the nylon of the last layer will form the outer or skin surface of the package. T7225B™ is used as a lidstock (non-forming) web. 
     Referring to the drawings, the first side panel  12  has a top portion  9 , a first side edge  31 , a second side edge  33 , and a lower portion  17 . The second side panel  14  has a top portion  11 , a first side edge  35 , a second side edge  37 , and a lower portion  18 . The first and second side panels  12  and  14  are joined together along their respective first and second side edges by either a seal or a fold. As shown, first side edge  31  of first side panel  12  is joined to first side edge  35  of second side panel  14  by a seal  30 . Second side edge  33  of first side panel  12  is joined to second side edge  37  of second side panel  14  by a heat seal  32 . The second end  34  of the pouch  7  can be either a seal or a fold. Where a single web is used to make the pouch, second end  34  will typically be a fold, although even after the web is folded, a seal such as a heat seal can optionally be installed in the area of the fold. Where two webs of film are used to make panels  12  and  14 , second end  34  will be a seal that joins panels  12  and  14  together along their respective lower portions  17  and  18 . The two webs can be from the same material, or can be different in composition, structure, etc. 
     B. Discrete Laminate 
     1. Geometry and Placement in Package 
     A discrete laminate  4  includes a panel section  6  having an outer surface  66  and inner surface  67 , and a base strip  10  including a monolayer or multilayer sealing segment  22 , an intermediate layer 19 comprising PSA, and a monolayer or multilayer backing segment  20 . The discrete laminate, panel section, and base strip can each be of any suitable dimension and shape, and will typically be longer in length than in width, with the length being e.g. greater than two times the width, e.g. greater than 3, 4, or 5 times the width. A typical dimension for the discrete laminate is a width of from about 1 to 1.5 inches and a length of about 4 to 10 inches. The strip  10  will be shorter in one dimension than the pouch and package. For example, the strip can extend across the transverse width of a pouch made in e.g. a HFFS or VFFS process, but will be significantly narrower than the length of the package (see e.g.  FIGS. 3 and 4 ). In one embodiment, the strip will occupy less than 50%, such as less than 40%, less than 30%, less than 20%, or less than 10% of the length of the package. 
     In some embodiments, an opening flap  26  (e.g.  FIGS. 28A to 28D ) provides a device that can be manually grasped and pulled back to open the package, and access the contents of the package. The size of the package, type of materials used for the pouch and the strip, the seal strength of the materials used in the strip, and the type of product being packaged can all have some effect on the choice of the optimal length and dimensions of flap  26 . 
     Base strip  10  comprises a first surface  23  and a second surface  25 . At least the first surface comprises a sealant. In one embodiment, both the first and second surfaces comprise a sealant. The first surface  23  is sealed in one embodiment to the inner surface  27  of the first side panel  12  and the inner surface  67  of the panel section  6 , and the second surface  25  is sealed to the inner surface  29  of the second side panel  14 . Either or both of the sealants of the base strip are in various embodiments an easy open sealant. In another embodiment, only the first layer of the sealing segment  22  comprises an easy-open sealant. 
     When a product  24  is placed in the pouch  7 , by any suitable process such as processes herein disclosed, and the pouch  7  is closed, the package  5  is made. 
     The base strip and the layers thereof can each be of any suitable thickness. The base strip can for example have a thickness of between 2.0 and 5.0 mils, such as between 2.5 and 4.5 mils, between 3.0 and 4.0 mils, or any thicknesses therebetween. Factors such as the composition of the base strip, arrangement of layers within the base strip, and flexural modulus of the materials used may affect the choice of appropriate thickness of the base strip. The PSA layer 19 can also have any suitable thickness, typically 0.5 mils, e.g. between 0.1 mil and 1 mil, or 0.2 mils and 0.8 mils, etc. 
     Any suitable web, including any of the hybrid materials of the type described herein for web materials, e.g. H7225B or a non-barrier analog of such material, can be used to make the panel section  6 . Any suitable film can be used to make the base strip  10 . 
     As shown in the drawings, a first portion of the first surface  23  of the base strip  10  is anchored to the inner surface  67  of panel section  6  at a first location (anchor region “D”) to form a first anchor seal  63 . The first anchor seal  63  can be positioned in different embodiments at various locations on the inner surface  67  of the panel section  6  with respect to the location of the die cut or die cuts  21 . 
     The discrete laminate  4  is anchored to the first side panel  12  at a second location (anchor region “A”) to form a second anchor seal  68 . The second anchor seal can be made in various embodiments, in some cases involving the first or second surface of the base strip  10 , and in some cases involving the outer or inner surface of the panel section  6 . These embodiments are described further herein. In the embodiment of  FIGS. 5A and 5B , a second portion of the first surface  23  of the base strip is sealed to the inner surface  27  of the first side panel to form the second anchor seal. In an alternative embodiment, discrete laminate  4  is anchored to the first side panel  12  by sealing a second part of the inner surface  67  of panel section  6  to the outer surface  59  of first side panel  12 . 
     Anchor seals  63  and  68  can be made at any suitable time before or during the manufacture of a package. 
     In some embodiments, to facilitate opening of the package, at least one of the die cuts  21  in the panel section  6  should be disposed outside the portion of the panel section underlain by the base strip  10 . In some embodiments, at least one die cut, or a portion of a die cut, is disposed closer to the first end of a pouch than the first end  28  of the base strip, i.e. the end of the base strip closest to the first end of the pouch. 
     2. Base Strip Construction 
     The base strip  10  of the discrete laminate  4  of the invention is made from a multilayer film. A representative film structure suitable for use as the base strip  10  according to the invention is shown in  FIGS. 2 through 2D . In one embodiment, this film is a three layer coextruded film and has the composition shown in Table 1.

     In the embodiment of example 1, layer 22 functions as a sealant layer for sealing to a first portion of an inner surface of a panel section or surface of a web to be made into a panel section of a package. Layer 22 also comprises a single layer, and comprises sealing segment  22 . Layer 20 functions as a skin layer, and can function as a sealant for sealing to an inner surface of a second side panel or surface of a web to be made into a second side panel of a package. Layer 20 also comprises a single layer, and comprises backing segment  20 . Thus, either or both of sealing segment  22  and backing segment  20  can comprise, and consist of, only one layer. 
     A film of the construction of the film of Example 1 is commercially available in Europe, and sold as T174RC2™ from B-Pack, used as a primary web for a package, not as a base strip to be used in a package as disclosed herein. 
     Alternative three layer coextruded film structures, suitable for use in the invention, that were made in-house on a flat cast line include the films shown below in Table 2:

     In the embodiment of example 10, layer 109 functions as a sealant layer for sealing to a first portion of an inner surface of a panel section or surface of a web to be made into a panel section of a package. Layer 108 functions as a sealant support layer, and also as a tie layer to bond the sealant layer 109 to the PSA layer 119. Thus, in this embodiment, sealing segment  22  comprises two layers, layers 109 and 108. In general, sealing segment  22  can comprise any suitable number of layers, such as one, two, or three or more layers, as long as the easy-open/reclose functionality of the package made from the web and discrete laminate is maintained. 
     In the embodiment of example 10, layer 101 functions as a skin layer that in some embodiments can be used for sealing to the inner surface of a second side panel or surface of a web to be made into a second side panel of a package. Layer 102 functions as a tie layer to bond the skin layer 101 to the PSA layer 119. Thus, in this embodiment, backing segment  20  comprises two layers, layers 101 and 102. In general, backing segment  20  can comprise any suitable number of layers, such as one, two, or three or more layers, as long as the easy-open/reclose functionality of the package made from the web and discrete laminate is maintained. In some embodiments, backing segment  20  can include one or more functional layers such as e.g. oxygen barrier layers. 
     A commercial example of a film of the construction of the film of Example 10 is available in Europe, used there as a primary web for a package. 
     Another representative film structure suitable for use as the film strip  10  according to the invention is shown in  FIG. 7 . In one embodiment, this coextruded six-layer film has the composition shown in Table 4.

     In the embodiment of example 11, layer 109 functions as a sealant layer for sealing to a first portion of an inner surface of a panel section or surface of a web to be made into a panel section of a package. Thus, in this embodiment, sealing segment  22  comprises one layer, layer 109. 
     In the embodiment of example 11, layer 101 functions as a skin layer that in some embodiments can be used for sealing to the inner surface of a second side panel or surface of a web to be made into a second side panel of a package. Layer 103 functions as an oxygen barrier layer, and tie layers 102 and 104 bond the oxygen barrier layer 103 to the skin layer 101 and PSA layer 119 respectively. Thus, in this embodiment, backing segment  20  comprises four layers, layers 101, 102, 103 and 104.

     The oxygen barrier layer 103 of Examples 11 to 14 of the above film structures can comprise any suitable oxygen barrier material, such as EVOH, and can be blended in any suitable proportion with other polymeric materials or organic or inorganic additives as desired. Optionally, intermediate layers can be included on each respective side of layer 103, each comprising a nylon, e.g. 100% semicrystalline polyamide such as nylon 6. An intermediate layer of nylon can, in one embodiment, be placed on either or both adjacent surfaces of an EVOH or other barrier layer 103. 
     In packaging embodiments where the second surface  25  of base strip  10  is sealed to the inner surface of the second side panel along the entire width of the base strip  10 , an easy-open sealant, such as EZ1, can be used as sealant layer 101 of the base strip  10 . 
     Tie layers 102 and 104 can comprise any suitable polymeric adhesive that functions to bond two layers together, e.g. EVA, EAO, LDPE, EMA, and anhydride grafted derivatives of these polymers. Tie layers 102 and 104 can be the same, or can differ. 
     Layer 108 can comprise a suitable polyolefin, such as an EAO; and/or a polymeric adhesive such as those disclosed herein for tie layers 102 and 104. 
     Additional materials that can optionally be incorporated into one or more of the film layers of the discrete strip or the primary web, as appropriate, include antiblock agents, slip agents, antifog agents, fillers, pigments, dyestuffs, antioxidants, stabilizers, processing aids, plasticizers, fire retardants, UV absorbers, etc. 
     The sealant layers of the base strip, e.g. layer 22 and layer 20 as depicted in  FIG. 2 , or layer 109 and layer 101 as depicted in  FIGS. 6 and 7 , can comprise any suitable sealant material or blend of materials. Examples of such materials include the following polymers, their copolymers or blends: olefinic polymers such as ethylene polymer or copolymer, ethylene/alpha olefin copolymer, ethylene/vinyl acetate copolymer, ionomer resin, ethylene/acrylic or methacrylic acid copolymer, ethylene/acrylate or methacrylate copolymer, low density polyethylene, high density polyethylene, polypropylene, propylene/ethylene copolymer, propylene/ethylene/butene terpolymer; polystyrene, syndiotactic polystyrene, ethylene/styrene copolymer, and norbornene/ethylene copolymer. Ethylene/alpha olefin copolymers can include Ziegler/Natta or single-site catalyzed ethylene/alpha olefin copolymer such as ethylene/butene copolymer, ethylene/hexene copolymer, and ethylene/octene copolymer. Cycloolefin copolymers can be used. Non-olefinic copolymers can also be used, such as polyester and polyamide. Examples of polyester include homopolymers and copolymers of alkyl-aromatic esters, such as polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), crystalline polyethylene terephthalate (CPET), glycol-modified polyethylene terephthalate (PETG), and polybutylene terephthalate; copolymers of terephthalate and isophthalate, such as polyethylene terephthalate/isophthalate copolymer; and homopolymers and copolymers of aliphatic esters such as polylactic acid (PLA) and polyhydroxyalkonates, such as polyhydroxypropionate, poly(3-hydroxybutyrate), poly(3-hydroxyvalerate), poly(4-hydroxybutyrate), poly(4-hydroxyvalerate), poly(5-hydroxyvalerate), poly(6-hydroxydodecanoate) and blends of any of these materials. An example of a polyamide is a commercially available resin, GRILAMID™ XS1392 from EMS Grivory, comprising a blend of polyamide 6/12 and polyamide 12. For polyester and polyamide sealants on the base strip, the sealant layer of the panel section, or web to made into the panel section, that will be sealed to the base strip to make a package is selected to have the same or substantially the same chemical formulation. For example, if a polyester is used as the sealant for the base strip, a polyester is also used as the sealant for the inner surface of the panel section. Thus, the sealant materials as disclosed herein for a sealant layer of the base strip can be selected for the sealant layer of the panel section to which the base strip will be sealed. This selection can be made based on cost of materials, the strength of the seals made in the production of the package, and the like, and takes into account that the seal of the base strip to the inner surface of the panel section, or the portion of a web that becomes the inner surface of the panel section, is such that upon opening the package as described herein, a rupture of the sealing segment of the base strip occurs, and upon continued opening part of the PSA layer is exposed by delamination of the sealing segment/PSA interface of the base strip, and access is gained to the interior of the package. 
     The above discussion with respect to the base strip, and the choice of materials for sealants for the base strip and panel section, or webs to be made into the base strip or panel section, applies mutatis mutandis to the second anchor seal as well, and the first side panel or web to be made into a first side panel of a package. In embodiments where e.g. a second portion of the first surface of the base strip is to be sealed to the inner surface of a first side panel, or a web to be made into a first side panel of a package; or where a second part of the inner surface of a panel section, or a web to be made into a panel section, is to be sealed to the outer surface of a first side panel, materials can chosen as discussed above to make the second anchor seal  68 . The second anchor seal  68  can be either an easy-open seal, or a relatively strong seal, as long as functionally, the second anchor seal  68  remains intact during typical opening and reclosing of the package as disclosed herein. 
     The primary web, panel section and base strip of the invention can be made by any suitable process, including coextrusion, extrusion coating, lamination, extrusion lamination, etc. 
     3. Opening Mechanisms 
     The package of the invention can be easily manually opened. Any suitable mechanism or combination of mechanisms for obtaining this functionality and feature can be used according to the invention. The following are examples of such mechanisms. 
     If the second surface  25  of strip  10  is sealed to the inner surface  29  of second side panel  14  along substantially the entire length of the base strip, this seal is an easy-open seal involving one or more of the following mechanisms. In other embodiments, the second surface  25  of strip  10  is sealed to the inner surface  29  of second side panel  14  only along the side edges of the strip, as part of the perimeter seal or side seals of the package. In these embodiments, the seal between the second surface  25  and the surface  29  can be a relatively strong seal, provided the die cut segment is so positioned with respect to the base strip that the package can be opened and reclosed as disclosed herein. 
     The first surface  23  of strip  10  is sealed with a first anchor seal  63  to the inner surface  67  of panel section  6 . The first anchor seal  63  is an easy-open seal that will typically exhibit a combination of cohesive and delamination failure, or delamination failure, as disclosed herein. The second anchor seal  68  is typically a relatively strong seal, although an easy-open seal could be provided as long as the easy-open/reclosable functionality of the package is substantially maintained. 
     a. Adhesive Failure 
     In this embodiment, surface  25  and inner surface  29  each comprises a polymeric composition that, when surface  25  is sealed to surface  29 , forms an easy-open seal. This seal provides the interface that breaks apart upon manually opening the package. 
     In some embodiments, the polymeric composition of surfaces  25  and  29  will be the same or similar. Useful in these embodiments are the peel systems disclosed in U.S. Pat. Nos. 4,189,519 (Ticknor) (blend of EVA or EMA or EEA with crystalline isotactic polybutylene, and optionally with anhydride grafted EVA); 4,252,846 (Romesberg et al.) (blend of EVA and HDPE, optionally with IO or polybutylene (PBU)); 4,550,141 (Hoh) (blend of IO and polypropylene/ethylene copolymer (EPC)); 4,666,778 (Hwo) (three component blend of PE, that can be LLDPE, LDPE, MDPE, or HDPE, or EVA or EMA, with PBU, and PP or EPC); 4,882,229 (Hwo) (butene-1 polymer or copolymer blended with modified or unmodified LDPE); 4,916,190 (Hwo) (blend of butylene polymer or copolymer, with PE polymer or copolymer (LLDPE, LDPE, MDPE, EVA, EMA, EEA, EBA, or HDPE), with propylene polymer or copolymer); 4,937,139 (Genske, et al.) (propylene polymer or copolymer blended with HDPE); 5,547,752 (Yanidis) (blend of PBU and IO); and 5,997,968 (Dries et al.)(blend of Component 1 (a copolymer of ethylene and propylene or ethylene and butylene or propylene and butylene or ethylene and another-olefin having 5 to 10 carbon atoms or propylene and another-olefin having 5 to 10 carbon atoms or a terpolymer of ethylene and propylene and butylene or ethylene and propylene and another-olefin having 5 to 10 carbon atoms) and Component 2 (HDPE, MDPE, LDPE, LLDPE or VLDPE); these U.S. patents all incorporated herein by reference in their entirety. 
     In other embodiments, the composition of surfaces  25  and  29  will differ, i.e. dissimilar sealants are used. Useful in these embodiments are the peel systems disclosed in U.S. Pat. Nos. 3,655,503 (Stanley et al.) (LDPE or MDPE sealed to polypropylene (PP), EPC, saran, nylon 6, polycarbonate (PC), polyvinyl chloride (PVC), or polyethylene oxide (PEO); PP sealed to saran, nylon 6, PC, PVC, PEO, IO, phenoxy, or EVA; or nylon sealed to IO); 4,729,476 (Lulham et al.) (a blend of EVA and IO sealed to IO); 4,784,885 (Carespodi) (PP, HDPE, or LLDPE sealed to substantially linear PE (HDPE, LLDPE) blended with a polyolefinic thermoplastic elastomer such as ethylene propylene diene monomer (EPDM), EPM, butyl rubber, halogenated butyl rubber, isoprene rubber, and styrene butadiene rubber); 4,859,514 ((Friedrich et al.) (IO or IO blended with EVA, sealed to a blend of EVA and ethylene butene copolymer (EBC) and PP); 5,023,121 (Pockat, et al.)(a blend of PBU and PP and a third polymeric material selected from EVA, LDPE, LDPE, and IO, sealed to EVA, LDPE, LLDPE, or IO); these U.S. patents all incorporated herein by reference in their entirety. 
     b. Delamination Failure 
     In this embodiment, one of the interlaminar bonds between layers of the strip itself can be broken. Thus, the interlaminar bond provides the interface that will break apart upon manually opening the package. Useful in this embodiment are the peel systems disclosed in U.S. Pat. No. 4,944,409 (Busche et al.), this patent incorporated herein by reference in its entirety. 
     c. Cohesive Failure 
     In this embodiment, one of the layers of the base strip itself fractures when the package is opened. Useful in this embodiment is the peel system disclosed in U.S. Pat. No. 6,476,137 (Longo) (internal rupture of a sealant layer comprising a blend of an ionomer having a melt flow index of less than 5, and a modified ethylene/vinyl acetate copolymer having a substantially higher melt flow index, where the melt flow indices of the two polymers in the seal layer differ by at least IO), this patent incorporated herein by reference in its entirety. 
     Other peel systems useful in connection with the present invention are those disclosed in U.S. Pat. Nos. 4,058,632 (Evans et al.), U.S. Pat. No. 4,615,926 (Hsu et al.); U.S. Pat. No. 5,128,414 (Hwo); U.S. Pat. No. 6,395,321 (Schaft et al.), U.S. Pat. No. 7,055,683 (Bourque et al.), and US Patent Publication Nos. 20030152669 (Vadhar et al.) and 2008/0260305 (Shah et al.)

     Referring to  FIG. 2A , a discrete laminate  4  includes a panel section  6  including at least one die cut  21 , and a strip  10  anchored to a portion of the inner surface  67  of panel section  6  at anchor region “D” with a first anchor seal  63  (see also  FIGS. 5A and 5B ). The discrete laminate  4  is anchored to a portion of first side panel  12  at anchor region “A” with a second anchor seal  68 . In one embodiment, strip  10  is anchored to the inner surface  27 , e.g. with a relatively strong heat seal, at anchor region “A”. The second surface  25  of strip  10  is in one embodiment sealed to inner surface  29  of second side panel  14  with an easy-open seal. Anchor seals  63  and  68  can be made at any suitable time before or during the manufacture of a package. 
     In general, strip  10  can have any total thickness desired, and each layer can have any thickness desired, so long as the strip and package provide the desired functionalities. 
     Typical total film thicknesses are from 0.1 mils to 15 mils, such as 0.2 to 12 mils, such as 0.5 mils to 10 mils, 0.8 mils to 8 mils, and 1 mil to 4 mils. Suitable gauges include 1.5 mils, 2 mils (as in Example 1); and 3 mils. 
       FIG. 2B  is similar to  FIG. 2A , but in which the second surface  25  of strip  10  is not sealed to inner surface  29  of second side panel  14 , except by side seals. The embodiment of  FIG. 2B  offers the benefit of more usable space inside the package, because there is no seal (except at the sides of the package) of surface  25  to surface  29 , and therefore more space is available for product. 
     In an alternative embodiment,  FIG. 2C  is similar to  FIGS. 2A and 2B , but in which the surface  25  of the strip  10  provides an easy-open seal to the inner surface  29  of second side panel  14 , strip  10  is sealed at its first end to the inner surface  29  of the first end of the second side panel, and the inner surface  67  of the first end of the panel section  6 . The package made from the pouch of this embodiment can be opened by grasping or pinching the panel section and second side panel and pulling them apart from one another, in the manner in which e.g. a potato chip bag is sometimes opened, such that the easy-open seal at the first end of the package is broken, allowing access to the contents of the package. After the package is opened, the package can be reclosed by removing the die cut segment defined by strip  21 , exposing the PSA layer 19, and then folding over the first end of the package to contact and adhere to the PSA layer. Alternatively, the entire upper portion of the first side panel, including the PSA layer, and the second side panel, can be folded down onto the lower part of the first side panel to reclose the package. In some embodiments, in the unopened package, the die cut is completely shadowed (underlain) by the strip  10 . The embodiment of  FIG. 2C  offers the benefit of having the opening mechanism of the package (breaking apart the easy-open seal) different from the reclosing mechanism (removing the die cut segment, exposing the PSA, etc.). Thus, in this embodiment, the die cut segment does not need to be removed to open the package. This embodiment also allows for use of webs that do not respond particularly well to die cutting, e.g. laser die cutting. As an example, nylon, which is more difficult to laser die cut than PET, can be used as the web material. Even if a portion of the die cut is inadvertently cut all the way through the web, the underlying strip provides a backing material that protects the contents of the pouch and the initial hermeticity (if needed) of the package. 
     As shown in  FIG. 2C , the strip extends to the first end of the package. An alternative to  FIG. 2C  is like the embodiment of  FIG. 2C , but in which the first end  16  of the second side panel, and the first end  15  of the panel section, extend beyond the first end of base strip  10 , and define first and second opening flaps. In this embodiment, the package can be opened as described hereinabove, or alternatively the first and second opening flaps can be pulled apart to break the easy-open seal and access the contents of the package. An example of first and second opening flaps can be seen as flaps  509  and  511  respectively in  FIG. 17 . 
     Although these flaps are described in the context of a fin-sealed package made in a VFFS process, such opening flaps could be present in other described embodiments of the invention. 
     For many products, it is important to ensure hermeticity of the package during storage and distribution. This may be more difficult where one or more die cuts are present in the panel section of the package. Hermeticity is achieved in various embodiments of the invention where a seal anchors the panel section to the strip in anchor region “D”, and another seal anchors the discrete laminate to the first side panel in anchor region “A”, even though no seal (other than a side seal) adheres the second side panel to the strip ( FIG. 2B ). 
     In each of the embodiments of the package and process disclosed herein, a non-hermetic or hermetic package can be made in accordance with the invention. 
     At least one open-loop or closed-loop die cut is disposed on the panel section. Two or more die cuts can be disposed on the panel section, optionally one at a position closer to the first end of the package than the base strip, as well as a second die cut below or in the vicinity of the strip (see  FIG. 2D ). To open a package, a die-cut segment of material can thus be displaced or entirely removed from the panel section, exposing the first end of the base strip and a portion of the PSA layer. This first end can then be grasped and pulled up, allowing access to the contents of the package. 
     2. Method of Making a Package 
     A. Horizontal Form/Fill/Seal (HFFS) 
     HFFS packaging systems are generally well known to those of skill in the packaging industry, and can be used to make packages of the present invention. 
     Referring to  FIGS. 8 , and  9 A through  9 C, lay-flat web  300  is unwound from roll  302 , then advanced to forming plow  304  to convert lay-flat web  300  to folded web  305  (typically a centerfold film). The second end of each of the pouches to be made will comprise a second end fold  306 . Second end fold  306  therefore is equivalent to second end  34  of  FIG. 1 . This second end fold can be optionally sealed, or left as a folded second end of the pouch. 
     Side seals  308  are made to define a plurality of vertically arranged pouches  309 . Each pouch  309  is cut off from the trailing edge of web  300  by an appropriate cutting mechanism (not shown) such as a knife, at position  311 , a product (not shown in  FIG. 8 , but see product  24  in  FIGS. 1 to 5 ) is inserted or dropped into the open mouth  312  of each pouch, and the pouch mouth  312  is then closed by a suitable sealing mechanism such as a heat sealer (not shown) to create a seal  314 . 
     Discrete laminate  310 , equivalent to discrete laminate  4  of  FIGS. 1 to 5 , can be introduced into the HFFS process in a number of ways. For example, discrete laminate  310  can be unwound from a roll  315  in the vicinity of roll  302 , and disposed on lay-flat web  300  prior to, or as web  300  is being folded into folded web  305 . The discrete laminate is disposed on the web such that the discrete laminate overlaps the lay-flat web sufficient to allow the discrete laminate to be anchored to the web. Discrete laminate  310  includes a panel section  6  and base strip  10  as described herein. The panel section includes die cuts made in a predetermined pattern (see e.g.  FIGS. 28A to 29G ) to produce packages according to the invention. The base strip is anchored to the panel section with a first anchor seal  63 , and the discrete laminate is anchored to the lay-flat web  300  (or the folded web deriving from the lay-flat web) with a second anchor seal  68  by a suitable sealing mechanism such as a heat sealer (not shown). This second anchor seal  68  can be done in a variety of alternative embodiments (see e.g.  FIGS. 35 to 38 ). 
     First anchor seal  63  can be made before or as the discrete laminate is initially wound up onto roll  315 , e.g. by the manufacturer or assembler of the discrete laminate. The discrete laminate in this condition can be supplied to e.g. a packager of food or non-food products, who can then use the discrete laminate as disclosed in  FIG. 8  and the following figures for HFFS and the other processes disclosed herein. 
     Alternatively, the panel section  6  and base strip  10  can be supplied separately in e.g. roll form to a packager, who can then incorporate these components into the packaging process in any suitable arrangement, and can install the first anchor seal at any suitable stage in the packaging process to produce a package as described herein. 
     In any of these embodiments, discrete laminate  310  would thus be installed on the pouch (e.g. by installing the second anchor seal to seal the discrete laminate to the lay-flat web or folded web) in the same overall HFFS process (or other processes disclosed herein) that achieves production of the pouch, loading of a product into the pouch, and completion of the final package. Discrete laminate  310  is incorporated onto the pouch material and after cutting and sealing as described hereinabove, comprises an extension of the first side panel of each pouch as shown in  FIG. 8 , and  FIGS. 1 to 5 . 
     Alternatively, and referring to  FIG. 9A , discrete laminate  310  is shown as being installed on the lay-flat web prior to the start of the HFFS packaging process. This can be accomplished off-site from the processor, e.g. by the supplier of the web roll  302 . Thus, both the first anchor seal  63  and second anchor seal  68  are installed at point of manufacture or assembly, and the completed web with the discrete laminate anchored thereto is supplied to the packager. The packager can then use this material in the HFFS or other processes disclosed herein. 
     In yet another alternatives, the panel section  6  can be anchored (with a second anchor seal) to a lay-flat web at point of manufacture or assembly, and supplied to the packager, who can then anchor (with a first anchor seal) a separately supplied base strip  10  to the panel section; or conversely a base strip can be anchored (with a second anchor seal) to a lay-flat web at point of manufacture or assembly, and supplied to the packager, who can then anchor (with a first anchor seal) a separately supplied panel section  6  to the base strip  10 . 
       FIG. 9B  is a perspective view of a section of folded web as shown in the HFFS process and apparatus of  FIGS. 8 and 9A , as the lay-flat web is folded to create folded web  305 . The discrete laminate  310  is shown disposed, and optionally attached to, an inner surface  27  of one panel  12  of the folded web  305 , such that upon sealing the web to create a pouch, the discrete laminate functions as an extension of the panel. 
     The embodiment of  FIG. 9C  is similar to  FIG. 9B , but additionally shows an optional gusset  400  that can be made in the second end fold  306  of the folded web. The gusset can be optionally thereafter heat sealed. A gusseted second end provides a stand-up pouch feature in the final package. Gusseting can be accomplished by any suitable means known to those of skill in the art, such as a second forming plow (not shown) placed in-line in the manufacturing line at a position downstream of the forming plow  304 . The bottom area of the folded web takes on a generally “W” shape, i.e. a gusseted shape, in cross-section, with the outside legs of the “W” extending upwardly, and two parallel reverse folds to create the gusseted bottom. Seal opening or holes are previously punched in the inner legs of the “W” shape and aligned with one another so that the two outside plies can be sealed together through these holes. When the seals are made the panels are sealed to one another through the holes. One or more static plows may be mounted above the seal zone to form the gussets. Gusset holes can be die punched by a die at a hole-punch station which punches clearance holes at an appropriate position designed to be in general alignment with the side seal, adding rigidity to the gusset portion of the final package. This added rigidity enables the final package to stand up by itself when placed on a flat surface. 
     B. Vertical Form/Fill/Seal (VFFS) 
       FIG. 10  schematically illustrates a VFFS apparatus that can be used in conjunction with the apparatus and process according to some embodiments of the present invention. VFFS packaging systems are generally well known to those of skill in the art, and described for example in U.S. Pat. Nos. 4,589,247 (Tsuruta et al), U.S. Pat. No. 4,656,818 (Shimoyama et al.), U.S. Pat. No. 4,768,411 (Su), and U.S. Pat. No. 4,808,010 (Vogan), all incorporated herein by reference in their entirety. 
     Apparatus  40  utilizes a lay-flat web  41  as a rollstock. Product  42  is manually or mechanically supplied to apparatus  40  from a source (not illustrated), from which a predetermined quantity of product  42  reaches the upper end portion of forming tube  44  via funnel  43 , or other conventional means. The packages are formed in a lower portion of apparatus  40 , and web  41  from which the packages are formed is fed from feed roll  51  over certain forming bars (not illustrated), is wrapped about forming tube  44  (sometimes known as a “sailor&#39;s collar” or “forming collar”) and is provided with a longitudinal fin seal or lap seal  47  by longitudinal heat sealing device  46 , resulting in the formation of a vertically-oriented folded web in the form of a tube  48 . Transverse heat seal bars  45  operate to close and seal horizontally across the lower end of vertically-sealed tube  48 , to form a pouch  49  which is thereafter packed with product  42 . Film drive belts  52 , powered and directed by rollers, as illustrated, or by suitable alternative motive means, advance tube  48  and pouch  49  a predetermined distance, after which seal bars  45  close and simultaneously seal horizontally across the lower end of vertically-sealed tube  48  as well as simultaneously sealing horizontally across upper end of sealed pouch  49 , to form a product packaged in sealed pouch  49 . The next pouch  50 , thereabove, is then filled with a metered quantity of product  42 , forwarded, and the packaging cycle is repeated. It is conventional to incorporate with the seal bars  45  a cut-off knife (not shown) which operates to sever a lower sealed pouch  49  from the bottom of upstream pouch  50 . 
     Lay-flat web  41  of  FIGS. 10 and 11  will in operation travel upward, e.g. vertically upward from roll  51  to the forming tube  44 , and then downward, e.g. vertically downward for the remaining process steps. Discrete laminate  54 , equivalent to discrete laminate  4  of  FIGS. 1 to 5 , is unwound from roll  53  ( FIG. 12 ) to dispose discrete laminate  54  in overlapping relationship onto web  41  before, or as, web  41  is wrapped about forming tube  44 . When longitudinal seal  47  is made, discrete laminate  54  becomes part of the folded web. 
       FIG. 12  discloses the roll  51  of lay-flat web  41  according to one embodiment of the invention. Lay-flat web  41  has a first longitudinal edge  60  and a second longitudinal edge  62 . Discrete laminate  54  is fed from roll  53  onto a portion of lay-flat web  41 . Discrete laminate  54  has a first longitudinal edge  61  and a second longitudinal edge  69 . 
     Alternatively, and referring to  FIGS. 11 and 13 , discrete laminate  54  is already installed on the lay-flat web prior to the start of the VFFS packaging process. This can be accomplished off-site from the processor, e.g. by the supplier of the feed roll  53 , or according to any of the alternative assembly arrangements discussed above with respect to the HFFS process. 
     The discrete laminate includes die cuts on the panel section of the discrete laminate, the die cuts made in any predetermined pattern (see e.g.  FIGS. 28A to 29G ) to produce packages according to the invention. 
     In some embodiments, at least one of the web and the discrete laminate carries a registration device. Printed indicia can be in the form of registration marks, such as eye-spots. Those skilled in the art will be familiar with the use of eye-spots and registration marks in processing web material in packaging operations. Registration marks are printed in uniformly spaced fashion along or near an edge of the web or strip, and facilitate the controlled production of packages of the invention, and can be printed in conjunction with other decorative printing. 
       FIG. 14  shows a discrete laminate  4  of the invention, which can be used in the various processes and packages disclosed herein, e.g. as a discrete laminate  54  of  FIGS. 12 and 13 . Discrete laminate  4  includes base strip  10  and panel section  6  including die cut(s)  21 . 
       FIG. 15  shows a discrete laminate  54  of the invention (see also  FIG. 12 ) that has been anchored to lay-flat web  41 . In the embodiment shown in  FIG. 15 , the discrete laminate is anchored to the lay-flat web  41  at a second portion of a first surface of base strip  10  to form a second anchor seal  68 . Joint  13  represents the gap between and juxtaposition of a second end of panel section  6 , and a first longitudinal edge  60  of the lay-flat web that will become a first end of first side panel  12  in the package of the invention. The first longitudinal edge  61  of discrete laminate  54  will become the first end of panel section  6 . The exact dimension of joint  13  can vary depending on manufacturing tolerances when combining the discrete laminate with a web. 
       FIGS. 31 and 32  show a discrete laminate  4  in accordance with the invention. The discrete laminate includes a panel section  6  including an outer surface  355 , an inner surface  356 , a first side edge  353 , a second side edge  354 , a first end  351 , a second end  352 , and a die cut  21 ; and a base strip  10  including a first surface  361 , a second surface  362 , a first side edge  360 , a second side edge  359 , a first end  357 , and a second end  358 . Each of the components of discrete laminate  4  can have any suitable dimensions, and in some embodiments base strip  10  and panel section  6  can be congruent, provided that the first end  351  of panel section  6  extends beyond the first end  357  of base strip  10 . As shown in  FIG. 32 , base strip  10  includes a splice area “S” that extends beyond the second end  352  of panel section  6 ; and panel section  6  includes an area that extends beyond the first end  357  of base strip  10 . These extended areas in some embodiments serve as areas that can be anchored to a web or first side panel of a package of the invention; or, in the case of the panel section, serve as an upper or end portion of a first side panel of a package that can function as part of an opening or removable flap. In some embodiments, both the first and second ends of the panel section can extend beyond the first and second ends respectively of the base strip. 
     Although for purposes of illustration  FIG. 32  shows the first and side edges of the base strip as extending beyond the first and side edges of the panel section, typically in packages of the invention the first and second side edges of the panel section will be congruent with the first and second edges respectively of the base strip. 
     In  FIG. 16 , a leading or downstream pouch “L” includes a transverse bottom and top seals  78 , folded side edges  81  and  82 , and longitudinal seal  47 . Trailing or upstream pouch “T” has features similar to leading pouch “L”. Leading pouch “L” is severed from upstream pouch “T” at cut line  80 , and the seals  78  are made by suitable sealing equipment commonly used in VFFS packaging processes, such as heat sealing equipment, not shown. For the sake of clarity, die cuts  21  and optionally  36 , present in the first side panel of the package, are not shown in all of the drawings. The discrete laminate is not shown in  FIG. 16 . 
       FIG. 17  shows folded web  500  with a discrete laminate  502  anchored to a folded web, and fin seal  501 , formed as disclosed hereinabove, and prior to a step of making transverse seals in the folded web. A finished package made according to  FIG. 17  will thus look like the packages of  FIGS. 3 and 4 , when these are viewed at right angles to their position in  FIGS. 3 and 4 , i.e. with the discrete laminate  4  to the right side of each package, and the second end  34  representing a fold. The embodiment of  FIG. 17  thus provides a method of producing packages on a VFFS apparatus where the longitudinal seal of the package effectively becomes the first end of the finished package (discounting any unsealed material between the longitudinal seal and the top edge of the package). The apparatus and methodology of U.S. Pat. No. 6,293,073 (Caudle) this patent incorporated herein by reference in its entirety, can be utilized in combination with the teachings herein, to produce packages according to this embodiment. A point of distinction is that in the present invention, the transverse seals will typically (although not necessarily) be rectilinear, whereas the trans-verse seals disclosed in Caudle &#39;073 are wavy or sinusoidal. 
     Alternatively ( FIG. 18 ), a package like the embodiment of  FIG. 17  is shown, but where a lap seal  503  is shown. In this as well as the other processes disclosed herein, a lap seal can be used in lieu of a fin seal when making a longitudinal seal according to the invention. A finished package  5  according to  FIG. 18  has a product therein; the two longitudinal ends of the package are closed by a transverse seal; the lap seal runs down the middle or spine of the package, bounded on both ends by the transverse seals; and the discrete laminate is anchored to an interior surface of the folded web. 
     C. Lidstock/Formed Web 
       FIGS. 19 ,  20 , and  21  illustrate in another embodiment the use of a formed web, e.g. a tray, and a non-formed web, e.g. a lidstock, used in connection with the invention. Tray  602  will typically be made during the packaging process. Thermoforming equipment, available from e.g. Multivac, Tiromat, Ulma or Rapid Pak, is used to convert flat thermoplastic forming web into formed pockets to create trays for containing product such as food, various industrial and consumer items and sterile medical products. Trays are formed from a lower web by heat and pressure, and can be loaded with product manually or automatically on the machine. After that, the packages are vacuumized or backflushed with modified atmosphere (if required), hermetically sealed to an upper web, separated, and removed for distribution or storage. Alternatively, pre-formed trays can be used. 
     Each tray  602  has a tray bottom  604 , tray sides  606 , and a tray flange  608  along its perimeter to which the lidstock  612  can be sealed by heat or other means. Tray bottom  604  and tray sides  606  define tray cavity  610 . Prior to any thermoforming step, tray  602  can be of any suitable thickness, e.g. from 2 to 30 mils thick, and any suitable construction. 
     If a pre-made tray is used according to the invention, it can be rigid or semi-rigid, can be in the form of a flat or shaped tray, and can be made from any suitable material, including solid or expanded embodiments, such as PP, polystyrene, polyamide, 1,4-polymethylpentene (e.g. TPX™ available from Mitsui), poly(vinyl chloride) (PVC), or a polyester or copolyester such as poly(lactic acid) (PLA), crystallized polyethylene terephthalate (CPET), or amorphous polyethylene terephthalate (aPET). 
     In one embodiment, a tray can be made from a flexible forming web. Examples of materials suitable for use as flexible forming webs are T7280B™ and T7050B™, both available from the Cryovac business unit of Sealed Air Corporation. 
     A tray liner can optionally be used that adheres to the surface of the pre-made tray on which the product is to be placed. This liner can be of any suitable design, and can be a multi-layer structure optionally with at least one layer with gas-barrier properties, and typically with a sealant layer or surface that facilitates sealing of the pre-made tray to a lidstock. Such a liner can be adhered to the tray by heat lamination, extrusion lamination, extrusion coating, adhesives, corona treatment, etc. Tray  602  can be a flexible or semi-rigid, or rigid formed web. 
     In an alternative embodiment, a tray be made in situ, e.g. using a Multivac thermoforming machine. Any suitable material can be used as the forming web for making an in situ tray. For example, V716B™, provided by the Cryovac business unit of Sealed Air Corporation, is a forming web that is offered commercially to make an in situ tray. This material includes a PVC substrate, and a multilayer coextruded sealant film, adhered to the PVC substrate, that includes an oxygen barrier layer and a sealant layer. The sealant layer of the forming web facilitates sealing of the lidstock to the tray made from the forming web. 
     Referring to  FIGS. 20 and 21 , a package includes tray  602  to which lidstock  612  has been sealed with perimeter seal  614 . Lidstock  612  includes a lay-flat web  611  (see  FIGS. 22 and 23 ) formulated to function as a lid on a formed web, and can be any suitable monolayer or multilayer thermoplastic film as described herein with respect to webs useful in connection with the present invention. Lidstock  612  also includes discrete laminate  616  having an easy-open sealant on one surface thereof, and a sealant on a second surface thereof. Discrete laminate  616  has the easy-open characteristics and composition discussed herein with respect to the discrete laminate of HFFS or VFFS packages. The panel section at die cut  621  (see also  FIG. 29A ) can be pulled back manually toward the end of the package, along hinge line  58 , and the first side panel is grasped so that the package is easily opened and product can be removed as desired. After removing the product, the package can be reclosed by bringing flap  626  back down on PSA layer 19. 
     In some embodiments where the formed web is rigid or semi-rigid, an open loop die cut can be configured so as to form a flap when opened, as shown in  FIG. 21 , with a hinge line at one end of the flap. In other embodiments where the formed web is flexible, the die cut can be as described above (i.e. an open-looped die cut with a hinge line) or can be a closed-loop die cut that can be completely removed when opening the package. In the latter case, the package can be reclosed by folding the flexible formed web over, contacting the PSA. 
     Referring to  FIG. 22 , discrete laminate  616  has a first lateral edge  111 . As shown, discrete laminate  616  has been anchored to the lay-flat web  611  to produce lidstock  612 . Dotted lines  107  indicate the location at which lidstock  612  is sealed and cut, e.g. perimeter heat sealed and cut, in registered fashion by otherwise conventional means as discussed herein, e.g. in thermoforming equipment, to create individual packages. Lines  107  represent what will become the side edges and seals of individual packages when lidstock  612  is advanced into a packaging system where it is progressively fed over filled trays, sealed to the trays, and cut to create finished packages. Lines  111  and  140  also represent what will become the first and second end respectively of individual packages. Lay-flat web  611 , as rolled up, and as it feeds into thermoforming equipment, has a first lateral edge  140 . Discrete laminate  616  can be preanchored on lay-flat web  611  by the supplier of the lidstock, as in the embodiments of  FIGS. 9A ,  11  and  13 . Alternatively, discrete laminate  616  can be anchored to the lay-flat web  611  during the packaging process, as in the embodiments of  FIGS. 8A ,  10 , and  12 . 
       FIG. 23  shows an alternative embodiment of  FIG. 22 , in which the lidstock is produced as described above, but “two across”, so that when run in a packaging machine, with suitable machine die set-ups, two, four, etc. packages can be made simultaneously. In addition to the seal and cut steps at locations  107 , the web is cut longitudinally along line  121 , so that individual packages made from the longitudinal portion “X” of  FIG. 23  will have a second end  121 ; and individual packages made from the longitudinal portion “Y” of  FIG. 23  will have a second end  121 . 
     D. Continuous Horizontal Packaging 
     In another embodiment, and referring to  FIGS. 25 and 26 , the package of the invention can be made using a continuous HFFS process and apparatus such as those used for packaging bakery and other goods, sometimes known as Flow Wrap, Flow-Wrap or Flow wrapping machines or systems, and available from manufacturers/suppliers such as Ilapak, ULMA, and Bosch. 
       FIG. 25  shows such a process and apparatus  700 , but one in which a discrete laminate  724  is installed into a package. Lay-flat web  702  is drawn from roll  704  and advanced to forming device  710 . As this occurs, a series of products  706  is advanced along conveyor  708  to forming device  710 , and discrete laminate  724  is drawn from roll  726  and advanced to forming device  710 . Web  702 , with the discrete laminate in some embodiments anchored thereto either before or during forming of the web in the forming device, is formed by forming device  710  into folded web  712 . This folded web will be like the folded web described above with respect to VFFS embodiments, but in a substantially horizontal orientation. Folded web  712  wraps around products  706 . A longitudinal sealing device that can be part of forming device  710  forms a lap or fin seal (of the type disclosed above with respect to VFFS embodiments) on the folded web, typically at the bottom of the folded web. The lap or fin seal is typically a heat seal. An alternative is to have a separate sealing device  714  to produce the lap or fin seal. The products travel downstream from forming device  710  or sealing device  714  to transverse sealing device  716  where the folded web is transversely sealed in areas of the folded web between adjacent products. Such seals are typically heat seals. The products are advanced from transverse sealing device  716  to cutting device  718   a  and  718   b , where the formed and longitudinally and transversely sealed folded web is severed in areas of the folded web between adjacent products, in or near the transverse seals, such that individual packages  720  are produced. 
     Alternatively, the sealing function of transverse sealing device  716  and the cutting function of cutting device  718   a  and  718   b  can be combined at a single station, rather than being performed at separate locations on the production path. 
     Web  702  and discrete laminate  724  can be of any suitable dimension and composition, such as those disclosed herein. As discrete laminate  724  is fed to forming device  710 , it can be brought into contact with, and anchored to a surface of web  702 . This embodiment is shown in  FIGS. 25 and 26 , where discrete laminate  724  is shown as anchored to web  702  as it progresses toward forming device  710 . First longitudinal edge  703  of discrete laminate  724  can be seen in  FIG. 26 . Alternatively, discrete laminate  724  can be fed into forming device  710 , and then incorporated into folded web  712  by anchoring the discrete laminate to the interior or exterior surface of the web adjacent to the area of the formed web in which the lap or fin seal is made, and in a manner and format analogous to the embodiment of the VFFS pouch and package of  FIGS. 10 ,  17  and  18 , but in a horizontal rather than vertical position. In another embodiment, discrete laminate  724  can be pre-anchored to web  702  by the supplier of the web, analogous to the embodiment of the VFFS pouch and package of  FIG. 13 , and the HFFS pouch and process of  FIGS. 9A and 9B . Alternative methods of assembly, such as those disclosed for the HFFS process, can also be implemented. 
     E. Side Seal Bags 
     In one embodiment, and referring to  FIGS. 33 and 34 , the package of the invention can be made using otherwise conventional bag making equipment and processes. Bags are often made as side seal bags. The side seal bag has a factory-made heat seal at opposite bag edges. The bag bottom is formed by one of two folds of film created during the extrusion of bag tubing during manufacture. The opposite fold of film is slit to form a bag mouth. The bag is typically made from a long length of bag tubing. A method of making side seal bags is disclosed in US 2008/0138478 A1 (Ebner et al.), this patent incorporated herein by reference in its entirety. 
       FIGS. 33 and 34  illustrate bag  180 .  FIG. 33  illustrates a side seal bag  180 , in a substantially lay-flat view;  FIG. 34  illustrates a cross-sectional view taken through section  34 — 34  of  FIG. 33 . With reference to  FIGS. 33 and 34  together, side seal bag  180  comprises a web  182 , first edge  184  defining an open mouth, edge fold  190 , first side seal  192 , and second side seal  194 . Discrete laminate  191  is installed on the individual bag, or on a slit bag tube that is then cut and sealed at predetermined intervals to make a series of side seal bags  180 , by any suitable process such as any of those disclosed herein. 
     A bag can be made by extruding a thermoplastic tube to make a bag tubing; slitting the tubing at one longitudinal edge thereof to make a slit bag tubing; anchoring the discrete laminate as described herein to the slit bag tubing; and transversely cutting and sealing the bag tubing at predetermined intervals to make a plurality of individual bags each with the discrete laminate disposed thereon. The discrete laminate can function as described herein for other embodiments and processes, in providing an easy-open and reclosable package. Some of the steps set out in US 2008/0138478 A1, for making a bag, are optional with respect to the present invention; such steps including irradiation and orientation of the tubing. 
     At any time before transversely cutting the bag tubing to produce a bag, a first portion of the first surface of the base strip can be anchored to the bag tubing or slit bag tubing at a first location to create first anchor seal  63 , and at any time during the method of making the bag, the discrete laminate can be anchored to the bag tubing or slit bag tubing to create second anchor seal  68 . 
     In general, the discrete laminate can be anchored to the first side panel of a web, pouch, or package in a number of different configurations. An example is that shown in  FIGS. 2A and 2B . Alternatives are shown in  FIGS. 35 to 38 . 
       FIG. 35  shows the discrete laminate anchored to the first side panel  12  by anchoring a second part of the outer surface  66  of panel section  6  to the inner surface  27  of first side panel  12 . 
       FIG. 36  shows the discrete laminate anchored to the first side panel  12  by anchoring a second portion of the first surface of the base strip  10  to the inner surface  27  of first side panel  12 , and/or a second part of the inner surface  67  of panel section  6  to the outer surface  59  of first side panel  12 . 
       FIG. 37  shows the discrete laminate anchored to the first side panel  12  by anchoring a second part of the inner surface  67  of panel section  6  to the outer surface  59  of first side panel  12 . 
       FIG. 38  shows the discrete laminate anchored to the first side panel  12  by anchoring a second portion of the second surface of the base strip  10  to the outer surface  59  of first side panel  12 . 
     For each of these alternatives, In the event that the anchor is in the form of a seal, appropriate sealants should be present at surfaces to be anchored by sealing. 
     Method of Operation 
       FIGS. 5A and 5B  show a sequence for opening a package in accordance with the invention. An open-loop die cut  21  defines an intermediate end of panel section  6  which can be manually grasped and pulled up and away from the panel section  6  and back toward the first end of the package as a flap of material. As this action progresses, stress is put on the first anchor seal  63  that bonds a portion of the inner surface of the panel section  6  to sealing segment  22  of discrete strip  10  in region “D” (see  FIGS. 2A through 2D ) . Anchor seal  63  will typically be located at or near the first end  28  of discrete strip  10 . As force continues to be exerted on the flap of panel section  6 , sealing segment  22  ruptures down to the PSA layer  19 , as a cohesive failure mechanism, and continued pulling on the flap partially removes the sealing segment from the discrete strip, by delamination of the strip at the sealing segment/PSA interface, thereby partially exposing the intermediate layer  19  comprising a PSA at exposed PSA portion  65 . 
     In some embodiments, depending at least in part on the choice of materials, cohesive failure within intermediate layer 19 may occur. This can result, upon opening of the package, in a portion of the PSA of layer 19 remaining adhered to the backing segment, and a portion of the PSA of layer 19 remaining on the sealing segment that has been separated from the base strip  10 . 
     During this opening sequence, the second anchor seal  68  in region “A” that in this embodiment seals surfaces  23  and  27  of first side panel  12  will typically remain intact, such that a portion of sealing segment  22 , and the strip  10  as a whole, stays on and in contact with surface  27 . Continued pulling of the flap exposes the first end of strip  10 , allowing access to the contents of the package by pulling the first end of the strip toward the user, i.e. away from the second side panel  14 . In embodiments where the backing segment  20  is sealed to the inner surface  29  of the second side panel, by an easy-open seal, the action of pulling the first end of the strip toward the user will break the easy-open seal to permit access to the package interior  57 . 
     To reclose the package, the flap of the panel section can be placed down on the PSA, or the panel section and second side panel can both be folded over, along with the exposed portion of the PSA layer, to contact the lower part of the first side panel with the exposed PSA. The package can be opened and reclosed several times. When the package is opened, the PSA is positioned facing the outside of the package. This is useful especially with food products where it is undesirable to have the PSA facing the interior of the package, and thus potentially in contact with the product. 
     Another embodiment for opening a package in accordance with the invention is shown in  FIGS. 27A to 27D . A die-cut segment  56  defined by a first closed-loop die cut  21  (see also  FIGS. 28A to 28D ) is manually grasped and removed from the panel section  6 . Flap  26  is then grasped, and pulled up and back along a second die cut  36  toward the first end of the package along flap hinge  58 . As this action progresses, stress is put on the first anchor seal  63  that bonds a portion of the inner surface of the panel section  6  to sealing segment  22  of discrete strip  10  in region “D”. Anchor seal  63  will typically be located at or near the first end  28  of discrete strip  10 . As force continues to be exerted on the flap of panel section  6 , sealing segment  22  ruptures down to the PSA layer  19 , as a cohesive failure mechanism, and continued pulling on the flap partially removes the sealing segment from the discrete strip, by delamination of the strip at the sealing segment/PSA interface, thereby partially exposing the intermediate layer  19  comprising PSA. During this opening sequence, the second anchor seal  68  in region “A” that in this embodiment seals surfaces  23  and  27  of first side panel  12  will typically remain intact, such that a portion of sealing segment  22 , and the strip  10  as a whole, stays on and in contact with surface  27 . Continued pulling of the flap  26  exposes the first end of strip  10 , allowing access to the contents of the package by pulling the first end of the strip toward the user, i.e. away from the second side panel  14 . In embodiments where the backing segment  20  is sealed to the inner surface  29  of the second side panel, by an easy-open seal, the action of pulling the first end of the strip toward the user will break the easy-open seal to permit access to the package interior  57 . 
     To reclose the package, the flap of the panel section  6  can be placed down on the PSA, or the panel section and second side panel can both be folded over, along with the exposed portion of the PSA layer, to contact the lower part of the first side panel with the exposed PSA. 
     Here, and in  FIG. 29D , more than one die cut is present. The first die cut is in some embodiments closed-loop, i.e. the die cut defines a die-cut segment that can be displaced or completely removed from the first side panel of the package. The second die cut can also be closed-loop (see e.g.  FIG. 29D ), or can be open-loop and hinged ( FIGS. 28A through 28D ) such that the flap formed by a second die cut and a hinge line can be opened without removing the flap from the panel section of the package. Alternatively, a single die cut can be used, that is either closed-loop ( FIGS. 29B ,  29 E,  29 F) or includes a hinge line ( FIG. 29C ). Each die cut can be of any suitable geometry and depth. 
     Method of Making a Die Cut in a Web 
     A conventional die cutter can be used to create a first die cut  21 , and optionally one or more additional die cuts  36  in a web that is used to make panel section  6 . Die cuts can be made by any suitable conventional process and equipment. Any suitable pattern of die cut can be used, open or closed-looped, as long as it serves the function of providing an easy open package in which the packaged product can be accessed by means of a flap created at least in part by the die cut. Alternative patterns include elliptical, oval, triangular, three side rectangle, hour glass, “dog bone”, and other regular and irregular shapes. 
     The die cut extends completely through the panel section, or may extend through most of, but not entirely through, the thickness of the panel section. The die cut may extend through e.g. at least 50% of the thickness of panel section  6 , e.g. at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or 100% of the thickness of the panel section. 
     A laser system can be configured to produce a laser cut that cuts partly or completely through the panel section, or alternatively, a die cut can be made using a mechanical cutting system using rotary engraved dies, or steel rule dies supported in platens as used in reciprocating presses. The choice of die cutting technique depends on several factors, including the thickness and physical nature of the film or web to be cut. 
     The die cut may sometimes act as a tamper evident feature. 
     The die cutting of a web used to produce a panel section, and the assembling of a package incorporating a primary web, and a discrete laminate including a die cut panel section and a base strip, can be done at a single location, but more practically will typically be done at one or more separate locations, with the assembling of the package by a packager using pre-provided discrete laminate prepared elsewhere and provided in advance of the packaging process. 
     Method of Applying a Panel Section to a Strip to Make a Discrete Laminate 
       FIG. 24  shows a method of applying a panel section to a base strip to make a discrete laminate, comprising the following steps: 
     1) advancing base strip  10  by suitable motive means (not shown, and well known in the art, such as a motor) from roll  178 . 
     2) advancing panel section  6  from roll  176 . 
     3) bringing strip  10  and panel section  6  together at nip rolls  181 , 182 , and anchoring the strip to the panel section e.g. by heat sealing using a heat sealer (not shown). 
     4) installing a series of die cuts in panel section  6  at die cutter  183 . 
     5) advancing resulting discrete laminate  4  to take-up roll  185 . 
     In one embodiment, the panel section can be die-cut in advance of this process. This process can be done at a location where the package is made, or at a separate location. 
     Method of Application of the Discrete Laminate to a Web 
     The discrete laminate can be applied to a web such as a lay-flat web in a number of ways. 
     In one embodiment, the discrete laminate can be completely assembled, either at the package facility where it will be used to make packages, or at a supplier or converter location. The discrete laminate can then be anchored to a web as disclosed herein. Anchoring in this embodiment is accomplished e.g. by sealing an extended second end of the panel section of the discrete laminate to a surface of the web, or by anchoring an extended second end of the base strip of the discrete laminate to a surface of the web. 
     In another embodiment, the panel section and base strip are not brought together initially, and the panel section is anchored to one surface of a web, and the strip is separately anchored to an opposite surface of the web, and the base strip is anchored to an inner surface of the panel section. Attachment of the panel section and strip to the web can be done simultaneously, or sequentially with attachment of the panel section either before or after attachment of the strip. In this embodiment, the panel section and strip can be congruent, although they do not have to be.

     The overall thickness of the coextruded barrier film is about 2.50 mils. Layer gauges in mils for each layer are indicated below each layer. Layer 7 is the layer of the barrier film adhered, by the adhesive, to the PET film. Layer 1 is the heat sealant layer of the film, and the EAO (PE2) of layer 1 forms the inner or sealant surface of the panel section, facing the contained product, and the PET forms the outer or skin surface of the panel section. The thickness of the PET film is about 0.48 mils. The overall thickness of the laminate is about 3.0 mils. 
     Alternatives to the composition of layer 7 include various combinations of materials, including:
         96% PE3+4% AB1.   100% PE3.   76% PE3+20% PE8+4% AB1.       

     The base strip  10  of the package is as described herein for Example 11. 
     Before the package is made, the base strip is anchored to the H7530B panel section (specifically, to layer 1 of the coextruded barrier film of the H7530B laminate) while the latter is in a lay-flat condition to form a first anchor seal. A closed loop die cut is made in the panel section by a CO 2  laser prior to applying the strip to the panel section; the die cut defining a die cut segment that is positioned so as to result in the package as shown in  FIG. 2D . The discrete laminate  4  made up of the base strip  10  and die-cut panel section  6  is then anchored to the web making up the first and second side panel, and specifically anchored to a portion of the web that will constitute the first side panel, to form a second anchor seal. 
     Example 2 
     A package like that of Example 1 is made, but in which the coextruded barrier film of the panel section is a nine-layer film with a composition very similar to the seven layer film construction of Example 1, but having an additional intermediate layer of EV1, and an additional intermediate layer of a LDPE or a blend including LLDPE. 
     The above descriptions are those of embodiments of the invention. All parts and percentages are by weight, unless otherwise indicated or well understood in the art. Except in the claims and the specific examples, or where otherwise expressly indicated, all numerical quantities in this description indicating amounts of material, reaction conditions, use conditions, molecular weights, and/or number of carbon atoms, and the like, are to be understood as modified by the word “about” in describing the broadest scope of the invention. Any reference to an item in the disclosure or to an element in the claim in the singular using the articles “a,” “an,” “the,” or “said” is not to be construed as limiting the item or element to the singular unless expressly so stated. All references to ASTM tests are to the most recent, currently approved, and published version of the ASTM test identified, as of the priority filing date of this application. Each such published ASTM test method is incorporated herein in its entirety by reference. 
     Terms referring to polymers, such as polyester, polyamide, and polyolefin, refer herein to both homopolymers and copolymers thereof, unless otherwise specified. 
     With reference to the drawings, the flow of materials is in the direction of the arrows. 
     Those of skill in the art will recognize that the drawings herein are not necessarily to scale, and certain features of the invention may be graphically exaggerated for clarity. 
     Both the web or webs used in the manufacture of the package according to the invention, and the strip and strip of the discrete laminate of the invention, can be made by any suitable process, including coextrusion, extrusion coating, extrusion lamination, and conventional lamination using polyurethane or other adhesives. These manufacturing processes are well known in the art. Extrusion can be done in annular or flat dies. The extrudate can be hot blown or cast, and optionally solid-state oriented as desired. Chemical or electronic crosslinking of one or more layers of the webs or the strip can be done. Both web and discrete laminate can be advanced by suitable motive means (not shown, and well known in the art, such as a motor) from their respective rolls. 
     A package according to the invention can optionally carry printed indicia, which can be decorative or informational in nature. Decorative printed indicia can include a logo, a trademark, product information, etc. with text and/or graphics. 
     Printed indicia can be in the form of a message e.g. “easy open” or “open here”. This can be printed in scattered process (i.e. registration is not required) on or near the first end of the package. The message is surface printed or reverse printed. 
     In the embodiments disclosed herein, the first end of the package can be sealed, typically where two webs are used to make the package. Alternatively, the first end of the package can be a fold, e.g. where a single web of material is used to make the package. 
     The present invention, including the package and methods as disclosed herein, is provided in several embodiments in the absence of: plastic zipper closures; press-to-close or slide zippers; interlocking closures; reclosable fasteners with interlockable fastener elements; interlocking rib and groove elements having male and female profiles; interlocking alternating hook-shaped closure members, and the like. The package of the invention is provided herein in several embodiments in the absence of a discrete release liner for a PSA layer or coating. None of these aforementioned closures, zippers, elements, etc. is present in the package of the invention. 
     Although the invention is described in some embodiments herein as a package comprising a pouch comprising a first and second side panel each having a top edge, a first side edge, and a second side edge, those skilled in the art will understand, after a review of this disclosure, that in some embodiments, wherein a single web is used, the terms “side panel”, “top edge”, “first side edge”, “second side edge”, and the like are used for convenience to describe the relative locations or regions on a single web made into a pouch, so that the overall geometry of the package, and relative positions of the various features of the invention can be described. Thus, for instance, the first and second panels in a single web embodiment of the invention can be simply defined regions of the pouch, and the package made therefrom, and side edges are simply the side end lines of those regions. In such embodiments, the line of joinder of the side edges are the two side folds in the web that define the sides of the package. In contrast, in embodiments with two webs, each web when produced will have an identifiable first and second side edge, that will each be joined to a respective side edge of a second web. 
     Although the first and second side panels are shown in various embodiments as having the same length, the second side panel can be longer than the first side panel, i.e. extend beyond the first end of the first side panel. The extended portion can accommodate a hang tab with a hole therein. 
     In some embodiments, a seal can be applied obliquely across the two corners of the panel section of a package of the invention, closest to the first end of the package, such that it crosses over and seals two corners of the base strip to the panel section. These angled seals can be useful in facilitating the reclosure of the package after opening, and/or in assuring the integrity of the package before initial opening. An example is shown in  FIGS. 29A and 29G , where seals  751  are positioned obliquely with respect to the first end and sides of the package. The seal overlaps a portion of the die cut  21  at upper edges of the die cut. Optionally, the die cut can be discontinuous in the regions of the die cut where the angled seals  751  are present. 
     The invention is characterized by the fact that:
         the package before initial opening does not have a PSA on the exterior surface of the package,   before opening the package, the PSA is not in direct contact with the product inside the package,   after opening the package, the PSA layer effectively forms a portion of the outer surface of the first side of the package,   before opening the package, the PSA is not in direct contact with the outer surface of the first side panel, or of the outer surface of the second side panel,   once the package is opened, the PSA is on the outside of the package on a strip that acts functionally like an extension of the first side panel,   In some embodiments, a portion of the first side panel acts functionally as a closing flap.   In some embodiments, after opening the package, the first and second side panels can be folded over and the exposed PSA can be brought in contact with the outer surface of the first side panel.   because the PSA of the opened package, although exposed to the outside environment, faces away from the product, the chance of degradation of the PSA by contact with the product is reduced.
