Laminate material for vacuum-packed packages

摘要

A package is disclosed which is constructed from at least one flexible laminate panel having first and second plies. The panel has a strong bond between the first and second plies around a perimeter portion of the panel and relatively weaker bond between the first and second plies in a central portion of the panel. A portion of the first ply separates from the second ply upon the introduction of a vacuum to an interior cavity formed by the package. The relatively inner ply conforms to the package contents while the outside panel remains smooth.
