BIAXIALLY ORIENTED, LAMINATED POLYESTER FILM

摘要

Disclosed is a biaxially oriented, laminated polyester film having a Young's modulus of 10-250 kg/mm2 and formed by laminating layers of polyester B on both surfaces of a layer of polyester A having a glass transition temperature of not higher than 50.degree.C. This film not only has characteristics that the conventional polyester films do not possess, such as impact resistance, resistance to pinhole generation and lowtemperature performance, but also is excellent in flexibility. - 5 8
