METAL CAN WELDING PART REPAIRING FILM

摘要

PROBLEM TO BE SOLVED: To provide a repairing polyester film for a metal can welding part having impact resistance and adhesive properties or the like by solving problems of environmental characteristics, rustproofness or the like which has not been performed by a conventional coating type repairing agent. SOLUTION: The metal can welding part repairing film comprises a one side surface layer (A) made of a polyester a having a melting point of 180 to 240 deg.C and heat fusion bondability, an intermediate layer (B) made of an amorphous polyester b having a glass transition temperature of 60 to 150 deg.C or a crystalline polyester b' having a melting point lower by 10 deg.C or higher than that of the polyester a, and an another surface layer (C) made of a polyester c having a melting point higher than that of the polyester a of a laminated structure.
