ABSTRACT:
A process and apparatus for producing a laminate of metal and a polymeric film such as polypropylene bonded to a metal substrate such as steel or aluminum strip, preferably electrolytically chromium coated steel for making can ends, comprises laminating a polypropylene film to the metal and subjecting the film to a temperature above its melting point, and then uniformly and rapidly cooling the laminate to a temperature substantially below the melting point of the polypropylene by flooding the polypropylene coated surface of the laminate with cold liquid, e.g., water at room temperature.
