PROBLEM TO BE SOLVED: To provide a manufacturing method for a thermocompression bonding laminate film using a biaxially oriented polypropylene film for a substrate and containing water-based inks. SOLUTION: The manufacturing method for the thermocompression bonding laminate film is subjected to printing on the entire surface or a part of the biaxially oriented polypropylene film having easy adhesive property against the water-based inks. Then, the corona discharge treated surface of a laminated film composed of a polypropylene resin layer and a mixture resin layer comprising a polypropylene random copolymer resin whose surface is subjected to corona discharge treatment, and ethylene-1-butene random polymer and/or poly(1-butene); and the above printed surface are continuously subjected to thermocompression bonding lamination.
