  • Heat shrinkable multilayer packaging film of blended copolymers and elastomers
    Patent number: 4196240
    Abstract: A heat-shrinkable multilayer film suitable for use in the packaging of a frozen poultry, includes a first outer layer comprising a blend of propylene-ethylene copolymer having a high isotactic molecular structure with less than about 6% by weight being ethylene and having a melt flow of from about 1.5 to about 18 decigrams per minute; a (butene-1)-ethylene copolymer having a high isotactic molecular structure with less than about 10% by weight ethylene and having a melt flow of from about 0.1 to about 5.0 decigrams per minute, and a thermoplastic elastomer selected from the group consisting of ethylene-propylene copolymers and ethylene-propylene diene terpolymers, the ratio by weight of the propylene-ethylene copolymer to the (butene-1)-ethylene copolymer being from about 2:1 to about 1:2 and the thermoplastic elastomer being present from about 10% to about 50% by weight, and a second outer layer comprising an ethylene-(butene-1) copolymer having a melt flow of from about 0.1 to about 1.
    Type: Grant

  • Elastic multilayer packaging film containing plasticized polyvinyl chloride
    Patent number: 4156749
    Abstract: An elastic multilayer film suitable for use in connection with the packaging of poultry, comprises a first outer layer including a plasticized polyvinyl chloride having an inherent viscosity greater than about 1.10 and having a plasticizer content of from about 35 phr to about 40 phr, and a second outer layer including an ethylene vinyl acetate copolymer having a vinyl acetate content of from about 16% to about 20% by weight and having a melt flow of from about 1.0 to about 3.0 decigrams per minute.
