Abstract

A polyester film for forming which has excellent formability especially at a low temperature and low pressure, is excellent in solvent resistance and heat resistance, and is reduced in the burden to be imposed on the environment. The film comprises a biaxially oriented polyester film and is characterized by containing a copolyester and satisfying the following: (1) the stresses at 100% elongation in the machine direction and the transverse direction each is 10 to 1,000 MPa as measured at 25°C and is 1 to 100 MPa as measured at 100°C, (2) the storage moduli (E') in the machine direction and the transverse direction each is 10 to 1,000 MPa as measured at 100°C and is 5 to 40 MPa as measured at 180°C, and (3) the degree of heat distortion (initial load, 49 mN) in the machine direction as measured at 175°C is from -3% to +3%.
