ABSTRACT:
Multilayer laminates are made by extruding two polymeric films of different composition and forming them in contact with each other to provide a peelable interface, and forming a divisible core structure by permanently combining one of said films with a layer of pressure sensitive adhesive and combining the other film with at least one additional layer. The invention is useful for providing "dry" or non-tacky peelable labels and for providing renewable surfaces on articles such as trays or other substrates.
