<p>A biaxially oriented, laminated polyester film having a Young's modulus of 10-250 kg/mm2 and comprising a layer of polyester A having a glass transition point of 50 °C or below and sandwiched between layers of polyester B. This film not only has characteristics that the conventional polyester films do not possess, such as impact resistance, resistance to pinhole generation and low-temperature performance, but also is excellent in flexibility.</p> |
