Abstract (en)

[origin: WO9852747A1] A multilayer barrier packaging 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 thermoplastic polymer or copolymer, a first core layer of a barrier film comprising vinylidene chloride-methyl acrylate copolymer, a second core layer of a thermoplastic polymer or copolymer, a third core layer of a barrier film including vinylidene chloride-methyl acrylate copolymer, and a second outer layer of a thermoplastic polymer or copolymer. More specifically, EVA, LLDPE, VLDPE and blends of these materials may be used in the first and second outer layer and in the second core layer. The multilayer film is preferably made by co-extrusion of the layers, and then it is biaxially stretched. After biaxial stretching, the multilayer film may be irradiated to a dosage level of between 1 megarad and 10 megarads and heat-sealed in the form of a bag. The bag has improved storage stability characteristics.
