Abstract
A shrink bag having an integral carrying handle is provided that includes an extended lip bag of a heat shrinkable thermoplastic material and having a carrying hole in the lip with a continuous fused bead around its periphery, the carrying hole being spaced sufficiently below the top of the lip such that upon heat shrinking the bag about a product sealed therein enhanced thickening along the carrying-load bearing portion of the hole periphery occurs relative to the non-load bearing portion of the hole periphery. An associated method for making the bag is also provided.
Claims10
A shrink bag comprising an integral carrying handle, a rear bag panel, a corresponding front bag panel which is shorter than the rear bag panel, the front and rear bag panel forming an extended lip bag of a heat shrinkable thermoplastic material and having an unsealed bag mouth at one end of said bag and a carrying hole in said lip with a continuous fused bead around the periphery of said hole, said carrying hole being spaced sufficiently below a top of said lip such that upon heat shrinking said bag about a product sealed therein enhanced thickening along a load-bearing portion of said hole periphery occurs relative to a non load-bearing portion of said hole periphery.
A method for making a shrink bag having an integral carrying handle, comprising providing a rear bag panel, corresponding front bag panel which is shorter than the rear bag panel, the front and rear bag panel forming an extended lip bag of a heat shrinkable thermoplastic material and having an unsealed bag mouth at one end of said bag;
- and heat cutting a carrying hole in said lip to form a continuous fused bead around the periphery of said hole, said carrying hole being spaced sufficiently below a top of said lip such that upon heat shrinking said bag about a product sealed therein enhanced thickening along a load-bearing portion of said hole periphery occurs relative to a non load-bearing portion of said hole periphery.
