     DESCRIPTION 
       [0043]    The present invention relates to a bag having built-in handles for carrying large objects. In an embodiment, the bag is made of polyethylene. The bag is designed to protect against water, dirt and stains and provides a means of easily lifting, carrying and transporting a large object from one place to another. 
         [0044]    The handles are built into the extensions of the bag and are easy to grab while the object is standing vertically on its end, horizontally on its edge, or while laying flat. This eliminates the strain of having one or more persons trying to grip the object through the plastic in an effort to lift and move it with nothing to grab onto. The handles provide a convenient means of carrying an object for an extended period of time. The built in handles are placed in the extensions on one side of the bag as shown in  FIGS. 1 and 2  (with the opening on one end), the extensions on each side of the bag as shown in  FIGS. 3 and 4  (with the opening on one end), built in handles are placed in extensions on both ends of the bag as shown in  FIG. 5  (with the opening on one side) or handles on both ends and an opening at one of the ends as shown in  FIG. 6 . 
         [0045]    Any type of flexible material like canvas, vinyl, non-woven fabric, polyethylene, polypropylene, etc. may be used to produce this same type of bag with extensions to provide easy to grip, built-in handles. 
         [0046]    In an embodiment, the bag is made with sturdy cut-out handles built into an extension of multiple layers of film on one or both sides (or ends) that enables one or more persons, without strain, to carry the object placed in the bag. The object is inserted into the bag through the open end or side. After inserting the object, additional film is provided at the open end which is folded over and taped (sewn or sealed) closed. The object is then transported to its new location. The object can then be stored in the same bag to provide protection against soilage and water damage. After removing the object from the bag, the bag itself can then be folded and stored in a compacted form. 
         [0047]    By placing built-in, die cut handles in the film extended beyond the sealed area, the bag serves its primary function of protecting its contents, while providing the additional feature of allowing one or more persons to carry the bag by means of gripping the readily accessible built-in handles. 
         [0048]    The handles can be positioned at one or both sides (or ends) of the bag. Multiple handles can be placed in specific positions or at random through the film extended beyond the sealed area. 
         [0049]    In its most simple form, the bag is made with a lip on one side, where the die cut handles are built in, consisting of a single layer of film extended beyond the pocket of an open end bag. If needed, reinforcements can be applied to the handle area to provide additional strength. 
         [0050]    Sealing vertically along the entire inside edge of each bag bonds two or more layers of film together which allows the handles to be built into multiple layers of thinner, more cost effective film in the extended area beyond the vertical seals, while still providing adequate strength to carry heavy objects in the bag. 
         [0051]    Greater strength is achieved for the built-in handles by using multiple layers of film (four or more, instead of just two) in the area extended beyond the seals as shown in  FIG. 4 . 
         [0052]    In a preferred embodiment, the bag is produced in-line, so that the extrusion and bag making process is done without interruption until the bag is completed, including the die cut handles, sealed extensions and the sealed bottom. In a further embodiment, the bag is produced not in-line in a conversion process with the same die cut handles, sealed extensions and sealed bottom after the extrusion is completed. 
         [0053]    A wide variety of flexible film can be used to produce this type of carrier in bag form (closed at one end) or sleeve form (open at both ends), with built-in handles cut into the film extended beyond the enclosed interior area, at one or both sides (or ends) of the bag or sleeve. 
         [0054]    In an embodiment, vertically sealed extensions are provided on one or both sides as a means of providing multiple layers of film bonded together to produce greater strength for the handles in the area of film extended beyond the inner seals. 
         [0055]    In an embodiment, film extensions (with or without handles) are provided on one or both sides (or ends) to provide a means of easily gripping the bag. 
         [0056]    In an embodiment, heavier gauge film is used rather than multiple layers of film to support the handle grips placed in the extended area beyond the inner seals. 
         [0057]    Handles may be die cut only, die cut through a heat sealed patch reinforcement, burned through, applied as a rigid or flexible handle and riveted through the plastic with a cardboard reinforcement, or die cut through an applied pressure sensitive patch reinforcement.
