  • Package including a lidstock laminate
    Patent number: 6769227
    Abstract: A method of forming a package by heat sealing a trap-printed laminate to a support member (e.g., tray). The laminate has a free shrink in each of the transverse and machine directions of at least about 10% at 200° F. and at least about 21% at 240° F. The laminate has an oxygen transmission rate of no more than about 100 cubic centimeters. The outside layer of the laminate comprises at least about 40% of one or more relatively high-melt polymers each having a melting point at least about 25° F. higher than the lowest melting point polymer of the sealant layer. The first film has an oxygen transmission rate greater than the oxygen transmission rate of the second film.
    Type: Grant

  • Packaging material for long-term storage of food products
    Patent number: 5374459
    Abstract: A thermoplastic laminate suitable for long-term storage of food products includes a first substrate having a core layer of ethylene vinyl alcohol copolymer, two interior adhesive layers, and two surface layers each comprising a blend of a linear ethylene alpha olefin copolymer and an ethylene unsaturated ester copolymer; and a second substrate comprising an olefinic material of monolayer or multilayer construction, and preferably of substantiallly the same composition as the first substrate; and the second substrate bonded to the first substrate preferably by means of a conventional lamination adhesive.
