Abstract: 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.

Abstract: An unsupported lap-sealable liner for a composite container comprises a heat seal layer, a barrier web having a first surface attached to the heat seal layer and having an opposite second surface, and a sealable primer applied as an aqueous dispersion to the second surface of the barrier web and then dried. The sealable primer comprises a polymer having bonding affinity with wet adhesive used for bonding the liner to a paperboard surface of a composite container. The sealable primer furthermore is heat-sealable to the heat seal layer such that the liner is lap-sealable.

Abstract: A heat sealed pouch with tactile friendly edges is provided from the expansion of an expandable polymer, triggered either during the heat sealing process or subsequent to the heat sealing process. The pouch consists of two adjacent panels which are sealed along at least one edge.
