PROBLEM TO BE SOLVED: To provide a thermoplastic resin film which is excellent in lactic acid resistance. SOLUTION: A surface layer made of a methyl methacrylate-styrene copolymer resin and a polycarbonate resin overlies at least one side of a substrate layer made of a thermoplastic resin. The total thickness of the laminated film is preferably 20-500μm, the thickness of the substrate layer is preferably at least 0.5 times as thick as the total thickness, and the thickness of the surface layer is preferably 1-100μm. A methacrylic resin is used preferably as the thermoplastic resin, and especially the methacrylic resin incorporated with acrylic rubber particles is used preferably. COPYRIGHT: (C)2008,JPO&INPIT
