る方法を提供することを目的とするものである。As described above, in the two-layer structure of the resin film, it is difficult to precisely configure the resin film, and it is necessary to ensure the target adhesion to the surface-treated steel sheet. When the resin film laminated on the surface-treated steel sheet is processed into a can body, peeling of the resin film deteriorates the quality and loses the commercial value. In particular, when high-speed threading is performed to improve productivity, there is a problem that it becomes more difficult to form a laminated resin film with a precise two-layer structure. The method of the present invention has been made in order to advantageously solve such a problem, and after thermocompression bonding the resin film on the front and back surfaces, the surface of the surface-treated steel sheet is heated to melt the resin film lower layer (amorphous). In addition, it is an object of the present invention to provide a method for maintaining the upper layer crystalline and improving the adhesion to the surface-treated steel sheet.
