RESIN FILM FOR VACUUM FORMING

Provided is a fluorine-based resin multilayer film for vacuum forming which does not cause wrinkles and the like when a three-dimensional surface decoration method is applied. The fluorine-based resin multilayer film for vacuum forming includes a front surface layer containing 60% by mass to 85% by...

Zusammenfassung:	Provided is a fluorine-based resin multilayer film for vacuum forming which does not cause wrinkles and the like when a three-dimensional surface decoration method is applied. The fluorine-based resin multilayer film for vacuum forming includes a front surface layer containing 60% by mass to 85% by mass of a vinylidene fluoride-based resin and 40% by mass to 15% by mass of a methacrylate ester-based resin; and a back surface layer containing 0% by mass to 50% by mass of a vinylidene fluoride-based resin and 100% by mass to 50% by mass of a methacrylate ester-based resin, wherein the thermal dimensional change in a film flow direction when heated at 120° C. for 30 minutes, which is measured based on JIS K7133, is −15% to −2%.
