BIAXIALLY ORIENTED POLYESTER FILM FOR FORMING MEMBERS

摘要

[PROBLEMS] To provide a biaxially oriented polyester film, particularly a biaxially oriented polyester film for forming members which is useful as a substrate in producing metallic forming members by metal vapor deposition or as a surface protective film in the forming of decorative sheets. [MEANS FOR SOLVING PROBLEMS] A biaxially oriented polyester film for forming members, which is an at least two-ply laminate constituted of a layer (A) made of a polyester (A) and a layer (B) made of a polyester (B) wherein the interlaminar strength between the layers (A) and (B) is 5 N/15mm or above and the stress values (F100 values) at 100% elongation in the lengthwise and widthwise directions at 200°C and 150°C are 1 to 50 MPa.
