ABSTRACT:
Heat-sealable laminates useful as packaging materials, for example, for the packaging of photographic processing chemicals, are comprised of a layer of metal foil, an outer heat-sealable layer of a radiation-cured and heat-fused polymeric composition, and a radiation-cured chemically-resistant polymeric interlayer between the foil and the outer layer. The laminates are manufactured by coating a metal foil with a radiation-curable composition that is capable of forming a chemically-resistant layer upon radiation curing, irradiating the coating to cure it, overcoating with a radiation-curable composition such as a vinyl plastisol that is capable of forming a heat-sealable layer upon radiation curing, irradiating the overcoat to cure it, and heating the laminate to fuse the overcoat layer.
