  • Patent number: 6044622
    Abstract: A packaging method and apparatus perform the steps of:a. providing a film including a first film component peelably adhered to a second film component;b. providing a support member for supporting a product thereon;c. forming a seal between the second film component and the support member, the seal extending around the product to define a sealed enclosure for the product between the film and the support member;d. separating the first film component from the second film component within a predetermined region of the film located outside of the sealed enclosure; ande. severing the film within the predetermined, separated region to form an edge on the first film component within the separated region, thereby providing a tab for peeling the first film component from the second film component.

  • Patent number: 6042913
    Abstract: A composite film and vacuum skin package for packaging a product such as a fresh red meat is disclosed. The composite film is thermoformed and sealed under vacuum to a support member to completely enclose a product which is positioned on the support member. The composite film is a permeable film weakly bonded to an impermeable film, permitting the impermeable film to be peeled from the package while leaving the permeable film intact so that the fresh red meat product can bloom from a purplish color to a desirable red color upon exposure to oxygen. The permeable and impermeable films are fully peelable without the need for a migratable wax to enhance peelability.

  • Patent number: 5916615
    Abstract: A case-ready package and method of reducing discoloration in meat or poultry products enclosed within such packages when the packages are disposed in a stack of two or more packages. A non-textured and substantially smooth gas-permeable substrate is attached to the lower surface of the packages to allow air to flow into an underlying package in a stack of packages, thereby preventing or minimizing premature discoloration of packaged fresh meat or poultry product due to insufficient oxygen flow into such packages when disposed in a stack. In addition, the substrate may contain printed product indicia either directly or in the form of a label attached thereto.

  • Patent number: 5346735
    Abstract: A vacuum skin package for packaging fresh red meat and like articles is produced by using a composite, multilayer, oxygen barrier, vacuum skin packaging forming film in which the impermeable film can be manually separated from the non-barrier, oxygen permeable film. After the vacuum skin package is formed to enclose a fresh red meat product in a vacuum the meat will have a purplish color. Then, after storage, the impermeable film can be removed so that the remaining permeable film can admit oxygen to impart the desirable red bloom to the fresh meat. The oxygen permeable film preferably includes a core having enhanced permeation properties. The impermeable film preferably includes an EVOH layer sandwiched between ionomer layers for improved barrier properties.
