Laminates of plastic films to metals or to plastic films or of metals to metals joined together by thermal-activated bonding materials are made by winding long strips of the laminate materials in face-to-face and interleaved relation onto a core to form a roll, confining the outside of the roll to prevent it from unwinding and heating the roll to a temperature sufficient to activate the bonding material. The heating of the roll results in a differential thermal expansion of the core, the laminate materials and the roll-confining member that generates a bonding pressure. Various interleaf layers wound between layers of the laminate materials can be used to provide desired laminating pressures during the heating step.
