The first film F1 may be a CPP film (or LHD film) having a thickness of about 20 μm, and the second film may be an LHD film (or CPP film) having a thickness of about 60 μm. CPP film is a cast polypropylene (CPP) film used for lamination of food packaging paper.

The LHD film may have a composition of 60 wt% LLDPE, 30 wt% HDPE, 5 wt% Octane, and 5 wt% Metal.

A liquid adhesive having a polyurethane as a main material is applied to the back surface of the first film F1 unwound from the first film roll 51 , and then put into the drying duct 54 . The adhesive is contained in the tray 52 and the adhesive is applied to the back surface of the first film F1 by a pair of adhesive application rolls 53 . The adhesive may be mixed with an EVA curing agent. The first film F1 is continuously put into the drying duct 54 and dried for 3 to 5 seconds in a temperature environment of 30 to 50°C.

The second film F2 released from the second film roll 59 is laminated with the first film F1 passing through the drying duct 54 . The paper roll for performing lamination by pressing may be composed of a steel roll 55 and a rubber roll 57 . The first winding roll 61 for winding the laminated film F3 is input as a subsequent process.
