Abstract

A laminate of an oriented resin film and a metal sheet substrate is used in the manufacture of can stock, the intensity of orientation of the resin film being greater along the bottom of the can and lesser along the can side wall. This construction is obtained by locally cooling, during lamination, that part of the heated metal substrate which will become the bottom wall of the resultant can.
