  • Patent number: 4611456
    Abstract: The invention relates to a method of forming containers useful in vacuum packaging applications which require that the packaged product be wrapped in an air-impervious enclosure.According to one aspect of the invention, the method comprises a step wherein a substrate of an air pervious, semipervious or impervious material is mold formed, and a subsequent step wherein an impervious film is applied on the molded substrate and adhered thereto to produce an impervious substrate. In another aspect, a product is placed on the impervious substrate and enclosed by an impervious film in a vacuum skin packaging process.

  • Patent number: 4382513
    Abstract: An easily peelable heat seal between two sheets of cross-linkable polyolefin packaging materials is achieved by cross-linking the polyolefin material in each sheet by irradiating the sheets to a dosage level of at least 3 MR prior to heat sealing the sheets together. The easily peelable seal is especially useful where film surfaces in large flange areas are sealed together.
