ABSTRACT:
A heat-shrinkable, multilayer film suitable for use in fabricating bags for packaging primal and sub-primal meat cuts and processed meats. The multilayer film has a first outer layer of a first ethylene-vinyl acetate copolymer, a core layer of a barrier film as previously described comprising a polyvinylidene chloride vinyl chloride copolymer containing between about 70 weight percent and about 90 weight percent vinylidene chloride, and a second outer layer of a second ethylene-vinyl acetate copolymer. The multilayer film is preferably made by co-extrusion of the layers, and then it is biaxially stretched. After biaxial stretching, the multilayer film is irradiated to a dosage level of between 2 megarads and 3 megarads and heat-sealed in the form of a bag. The bag has improved toughness properties and heat-sealing characteristics, and is not significantly discolored by the irradiation.
