Abstract
A biaxially oriented polyester film includes at least three polyester resin layers A1/B/A2, and has a melting point in the range of 246 to 270° C. The major component of the layers A1 and A2 is polyethylene terephthalate and the stress at 100% elongation in the film's longitudinal direction and width direction at 150° C. and 200° C. meets the following equations: 2≦(F100+F100)≦100 and 1≦F100≦60. The film has a high dimensional stability at high temperatures to permit uniform metal deposition, suffers little change in appearance during thermoforming, and serves for easy production of formed parts that closely meet the shape of the die when subjected to low-stress forming.
