Coextruded multi-layer polyethylene film and bag construction

A thermoplastic bag structure having film walls comprising an inner layer and an outer layer coextruded therewith, said inner layer consisting essentially of branched low density polyethylene homopolymer and said outer layer comprising a resinous blend of a high density polyethylene homopolymer and linear low density ethylene-alpha-olefin copolymer, wherein said blend contains a major amount of said copolymer, said layer of low density polyethylene having a thickness on the order of from about 65% up to about 85% of the overall thickness of said laminate.

A multi-layer thermoplastic film comprising coextruded layers of branched low density ethylene homopolymer and a blend of crystalline high density ethylene homopolymer with linear low density ethylene copolymerized with a minor about of alpha-olefin, and wherein a predominant amount of film thickness is the branched low density ethylene homopolymer layer.
