Patent number: 4892603Abstract: 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 an ethylene-vinyl acetate copolymer, a core layer of a barrier film comprising vinylidene chloride-methyl acrylate copolymer, and a second outer layer of an 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 1 megarad and 5 megarads and heat-sealed in the form of a bag. The bag has improved storage stability characteristics.Type: GrantFiled: September 9, 1988Date of Patent: January 9, 1990Assignee: Viskase CorporationInventors: Stanley Lustig, Jeffrey M.

Patent number: 4865780Abstract: 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 including a polyvinylidene chloride vinylchloride 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.Type: GrantFiled: February 5, 1988Date of Patent: September 12, 1989Assignee: Viskase CorporationInventors: Stanley Lustig, Jeffrey M.

Patent number: 4863769Abstract: Heat-shrinkable films suitable for packaging food articles such as frozen poultry, primal meat cuts, and processed meat products. In one embodiment, the film may be a biaxially stretched monolayer film of a very low density polyethylene copolymer. In another embodiment, the film may be a biaxially stretched multilayer film comprising a first outer layer of an ethylene-vinyl acetate copolymer, a core layer of a barrier film such as a polyvinylidene chloride copolymer or an ethylene-vinyl alcohol copolymer, and a second outer layer comprising a blend of an ethylene-vinyl acetate copolymer and a very low density polyethylene copolymer. The multilayer film is preferably made by coextrusion of the layers. The films for fabricated into bags useful for the aforementioned purposes. The bags have improved toughness.Type: GrantFiled: April 24, 1987Date of Patent: September 5, 1989Assignee: Viskase CorporationInventors: Stanley Lustig, Nancy M. Mack, Jeffrey M. Schuetz, Stephen J.

Patent number: 4828891Abstract: A heat-shrinkable multilayer film suitable for use in fabricating bags for packaging primal and subprimal meat cuts. The multilayer film has a first outer layer of an ethylene-vinyl acetate copolymer, a first core layer of an oxygen barrier material, a second core layer of a polyurethane, and a second outer layer of a linear low density polyethylene. The multilayer film is preferably made by coextrusion of the layers, and then it is biaxially stretched. After biaxial stretching, the multilayer film is preferably irradiated to a dosage level of between 3 megarads and 8 megarads, and is then heat-sealed in the form of a bag. The bag has improved toughness properties.Type: GrantFiled: February 2, 1987Date of Patent: May 9, 1989Assignee: Viskase CorporationInventors: Stanley Lustig, Jeffrey M. Schuetz, Stephen J. Vicik
