METHOD FOR SEPARATION OF LAMINATED FILM

摘要

PROBLEM TO BE SOLVED: To obtain a method for separation of a laminated film wherein the surface film layer with small tensile strength can be easily separated by peeling and the base material film layer can be recovered thereby. SOLUTION: A laminated film 1 wherein a coating layer or a laminating layer 1b is formed on a base material film 1a is heated by heating devices 3 and 4 and a transfer roll 5 consisting of a substance with hot adhesiveness with the surface layer 1b is brought into contact with the coating layer 1b and it is heated and contact-bonded by means of a pressure roll 6 to transfer the coating layer 1b onto the transfer roll 5 and the base material film 1a is recovered thereby by separation and is reused.
