Process for making a vacuum skin package and product formed thereby

摘要

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.
