Abstract
A thermoplastic bag particularly adapted for the containment and storage of foods comprising a laminar bag structure having an interior layer of a high density polyethylene copolymer and an exterior layer of polypropylene. The layers are intimately and continuously bonded together at their interface. Such bag structures are suitable for the containment of foodstuffs while they are being heated or reheated following storage.
Claims5
A two-layer coextruded, thermoplastic laminar bag construction particularly suitable for the containment of food which has to be heated in aqueous media, said aqueous media being maintained at temperatures of up to about 212.degree. F., consisting of a continuous outer layer of polypropylene film and a continuous inner film layer of a high density ethylene-octene-1 copolymer, said copolymer comprising less than about 10% by weight of octene-1 and having a density of about 0.945 g/cc.
