ABSTRACT:
A multilayer film is disclosed having improved heat sealing characteristics, comprising a first outer layer containing a heat sealable thermoplastic polymer having substantial freedom from cross-linking bonds, and a second layer containing a cross-linked ethylene polymer. In one embodiment the multilayer film is suitable for use in packaging primal and subprimal meat cuts, said film comprising a first outer layer containing a heat sealable thermoplastic polymer; a core layer comprising an oxygen barrier film; and a second outer layer comprising an ethylene polymer having siloxane cross-linking bonds. In another embodiment the multilayer film contains a second core layer containing an ethylene vinyl acetate copolymer, which is located between the barrier core layer and the second outer layer.
