Abstract

An embossed metal foil laminate is prepared by laminating a metal foil to a paper web, utilizing an extrusion coated resin interlayer therebetween, by passing the layered structure between a nip roll and an engraved chill roll. The metal foil quickly conducts heat energy from the molten resin layer to the chill roll, allowing the process to be run at a high speed. The engraved chill roll impresses a pattern into the metal foil during the lamination operation.
