发明名称 Composite container having detachable liner and method for making container
摘要 A composite container having a detachable liner and a method for making the container are provided according to the present invention. The method includes providing a tubular body ply formed of a paperboard material and adhering the liner ply using a standard adhesive applicator. The method also includes heating a heat-releasable adhesive disposed between the liner ply and the body ply such that the liner ply substantially releases from the body ply. The liner ply remains adhered to the opposed ends of the container, thus providing a free medial portion between the opposed ends that can move inwardly if a negative pressure is created within the sealed container, thus equalizing the pressure within the container with that outside the container.
