  • Patent number: 6670023
    Abstract: A laminate generally includes: a. a multilayer, gas-impermeable film capable of delaminating into a gas-permeable portion and a gas-impermeable portion, the gas-permeable portion in adherence with the gas-impermeable portion at a predetermined intra-film cohesive strength; and b. a gas-permeable film bonded to the gas-impermeable film at a bond-strength that is greater than the intra-film cohesive strength between the gas-permeable and gas-impermeable portions of the gas-impermeable film. In this manner, when the laminate is subjected to a delaminating force, the laminate delaminates within the gas-impermeable film such that the gas-permeable portion of the gas-impermeable film remains bonded to the gas-permeable film. A package and method of making a package using the laminate as a lidding film are also disclosed.

  • Patent number: 6667067
    Abstract: A package which allows for butchering and packaging of fresh red meat at a centralized facility is provided which includes a an impermeable tray supporting the product, a first film sealed to the tray for enclosing the product, means defined within the first film for exchanging gases into and out of the package, and a second impermeable film enclosing the first film, such that removal of said impermeable film provides for the exchange of gases into and out of the package. The means for exchanging gases may be perforations defined within the first film, a second highly permeable film sealed to the first film, or an enlarged opening formed within the first film which is enclosed with a patch following adequate gas exchange at retail. Such gas exchange is required to release any low oxygen atmosphere and allow for the introduction of oxygen to the packaged meat product, said means for exchanging gases having a gas transmission rate of at least about 50,000 cc/m2/24 hrs./atm. at 73° F.

  • Patent number: 6651406
    Abstract: An apparatus for forming inflated containers includes a film web that includes two juxtaposed film plies, a closed longitudinal edge, an open longitudinal edge, and a series of transverse seals having a first end located at the closed longitudinal edge and a second end terminating a predetermined distance from the open longitudinal edge such that each of the juxtaposed film plies have a section extending beyond the second end of the transverse seals, thereby forming a skirt that extends between adjacent containers at the open longitudinal edge. Such skirt facilitates inflation of each container.

  • Patent number: 6432512
    Abstract: A foam plank laminate of thermoplastic material comprises at least two expanded foam sheets, both partially perforated, and laminated with the perforated surfaces facing each other and the smooth non perforated surfaces as the outer plank surfaces. The foam plank laminate can be obtained by an industrially acceptable production method as the partial perforation of the forming foam sheets accelerates the removal of a majority of the blowing agent from the foam structure, thus drastically reducing the curing time, and at the same time it has impermeability, good mechanical properties, and an attractive appearance.
