摘要 |
The biaxially oriented polyester film of the present invention contains a polyester having a primary melting point of 245 to 265° C. as the main component and exhibits a drop bag strength index at 0° C. of at least 2.0 and a strength at break in the film longitudinal direction at 120° C. of at least 100 MPa. The film has superior heat resistance, mechanical strength, impact resistance, and bending resistance and is particularly suitable for packaging materials.
