ABSTRACT:
A process for producing a cushioning laminate is described, comprising melting a laminated sheet comprising (a) a thermoplastic resin substrate sheet and (b) a thermoplastic resin adhesive layer having a heat distortion temperature at least 25.degree. C. lower than that of the thermoplastic resin which constitutes the substrate sheet (a); moving the laminated sheet below an upper mold in such a manner that the substrate sheet (a) faces the upper mold; vacuum molding the laminated sheet using the upper mold to produce a molded article having a desired irregular surface; and then bonding a plate-shaped member, such as a cardboard plate, a metallic or plastic plate, to the adhesive layer (b) of the laminated sheet while the above-molded article is brought into close contact with the upper mold, thereby producing the cushioning laminate having enclosed air pockets. This cushioning laminate is useful as a cushioning material for wrapping.
