ABSTRACT:
A multilayer film suitable for packaging a primal red meat cut comprising at least a first layer of a mixture of low molecular weight thermoplastic hydrocarbon resin and a polymeric resin selected from the group consisting of polyolefins and ethylene-vinyl acetate copolymers, and a second layer comprising acrylonitrile. The hydrocarbon resin serves as an adhesion promoter between the first layer and the second layer, and is selected from the group consisting of alpha-methyl-styrene copolymerized with styrene which may be 30 to 60 percent hydrogenated, and ethylene-vinyl acetate copolymers containing 8 to 30 percent by weight of vinyl acetate. A process for producing the multilayer films by coextrusion is also disclosed.
