ABSTRACT:
A composite container is provided for vacuum packaging of products which is constructed, as follows. A hollow body portion defines a desired shape for the container and has an inside surface. A liner layer is in superimposed position within the body portion and covers the inside surface for receiving the product inside the liner layer and the body portion of the container. An elastic material is positioned between the body portion and the liner layer for movably attaching the liner layer to the body portion in the superimposed position while allowing the liner layer to constrict and move away from the body portion by stretching of the elastic material when a vacuum is formed on the product packaged in the container and then allowing the liner layer to move back into the superimposed position within the body portion of the container by retraction of the elastic material when the container is opened and the vacuum on the product is removed.
