ABSTRACT:
Laminates comprising a film of heat-shrinkable synthetic resin and a metallic foil or metallized plastic film laminated to the resin film through a bonding layer which comprises a discontinuous layer of a synthetic resin which flows at a temperature for heat shrinkage and an adhesive layer which maintains its adhesive strength at that temperature. Upon heat shrinkage, the metallic foil or metallized plastic film will wrinkle at the portions in contact with the synthetic resin which is not highly adhesive at the temperature for heat shrinkage. The heat-shrunk laminate can be formed into a casing or container such as an electromagnetic interference shield, a packaging material, and decorative material.
