Easy peel film structure especially for retortable lidstock

摘要

Multi-layer films having an outer sealant layer which readily delaminates from the adjacent sealant layer are disclosed. For retort applications, preferably one of the outer or adjacent sealant layers is comprised of a majority of ethylene moieties and the other of the outer or adjacent sealant layers is comprised of a majority of propylene moieties. The film is especially well-suited for use as a lidstock sealed to a container, such as a tray.
