Abstract

A polyester film for molding uses exhibits excellent moldability, especially the moldability under processing conditions of low temperature and low pressure, and having excellent solvent resistance or heat resistance, and also having less environmental impact. The polyester film for molding uses of the present invention is characterized in comprising biaxial oriented polyester film, and the said film comprising copolyesters, and satisfying the following conditions: (1) The stresses of film at both longitudinal direction and cross direction as have been extended 100% are from 10 to 1,000 MPa at 25 DEG C, and from 1 to 100 MPa at 100 DEG C, and (2) The storage viscoelastic modulus (E') of film at both longitudinal direction and cross direction are from 10 to 1,000 MPa at 100 DEG C, and from 5 to 40 MPa at 180 DEG C, and (3) The heat deformation rate of film at longitudinal direction (with 49 mN of initial loading) is from -3% to +3% at 175 DEG C.
