  • Patent number: 8815358
    Abstract: A pouch-like package for long-term storage of a highly acidic condiment is fabricated from a flexible sheet material having a light-blocking sheet, such as aluminum foil, coextruded between a printable layer, which may be a polymeric material such as PET, and a barrier layer, which may be a polymeric material such as PET coated on one side by a thin layer of aluminum oxide. Suitable adhesives may be used between the printable layer, the light-blocking sheet, and the barrier layer. If desired, a sealant such as acrylonitrile may be applied to the surface of the barrier layer.

  • Patent number: 8815360
    Abstract: The present invention provides a multilayer film having an active oxygen barrier multilayer core comprising at least one of 1) an active oxygen barrier layer is sandwiched between two passive oxygen barrier layers, or 2) a passive oxygen barrier layer is sandwiched between two active oxygen barrier layers. In one embodiment, the active barrier layer comprises a composition that is a blend of a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and an oxygen barrier polymer (C). In some embodiments the active barrier layer may also include a compatibilizer (D). The passive oxygen barrier layers help to maintain the oxygen barrier properties of the multilayer film after the oxygen absorbing capacity of the active barrier layer has been exhausted. As a result, the useful shelf life of the film can be extended.
