  • Patent number: 8012520
    Abstract: A packaged product has a food product having an added liquid thereon, and a packaging article at least partially surrounding the food product. The packaging article having a seal layer comprising a member selected from the group consisting of a slip agent and a surfactant. The slip agent or surfactant causes contamination from the added liquid to bead up or wet out, respectively, thereby permitting heat sealing through the contamination with a lower leaker rate than would otherwise be the case.
    Type: Grant

  • Patent number: 6520332
    Abstract: A packaging cushion is disclosed for supporting and protecting objects during shipment. The cushion has upper and lower surfaces and one or more compartments for supporting the objects in positions so that the objects are higher than the lower surfaces of the cushions. The cushions may include upper and lower nodes which increase the separation distance between the objects when the cushions are stacked one on top of another. The cushions may be held in a stack by an outer box, or by wrapping the stack of cushions in a protective film, eliminating the need for an outer box.

  • Patent number: 5658625
    Abstract: Film and sheet materials, and articles made therefrom, such as bags, pouches, trays, etc., comprise one or more layers of a thermoplastic, homogeneous alpha-olefin/vinyl aromatic copolymer, preferably an ethylene/styrene copolymer. The alpha-olefin/vinyl aromatic copolymer has properties which can can provide a desired performance characteristics such as impact resistance, printability, RF sealability, free shrink, optics, as well as many others. The homogeneous alpha-olefin/vinyl aromatic copolymer may be present in a monolayer film, either alone or in a blend, or may be included in one or more layers of a multilayer film. Also included is a multilayer thermoformable article comprising a web having a film of such alpha-olefin/vinyl aromatic copolymers therto. Finally, also included is an RF-sealable film comprising such copolymers.

The alpha-olefin/vinyl aromatic copolymer has properties which can can provide a desired performance characteristics such as impact resistance, printability, RF sealability, free shrink, optics, as well as many others. The homogeneous alpha-olefin-vinyl aromatic copolymer may be present in a mono-layer film, either alone or in a blend, or may be included in one or more layers of a multilayer film. Also included is a multilayer thermoformable article comprising a web having a film of such alpha-olefin/vinyl aromatic copolymers thereto. Finally, also included is an RF-sealable film comprising such copolymers.
