METHOD FOR PROCESSING RESIN FILM FOR COATING METAL MATERIAL, AND RESIN FILM LAMINATED DECORATIVE PANEL

摘要

PROBLEM TO BE SOLVED: To provide a method for processing an embossed film capable of holding an embossed shape even if the embossed film is laminated on a heated metal to develop a sufficient design effect. SOLUTION: The storage elastic modulus E' of a resin is controlled to 4 x 107Pa or below to apply emboss processing, which forms unevenness with a ratio of average embossed groove depth/film thickness=0.1-0.4, to the surface of a film mainly comprising a polyester resin.
