<p>A biaxially oriented polyester film to be formed into containers, comprising a polyester containing 93 mol% or more of ethylene terephthalate as a component, and the breaking elongation in the machine direction (S MD) and the breaking elongation in the transverse direction (S TD), satisfying ¢Formula 1! and ¢Formula 2!, or a biaxially oriented polyester film to be formed into containers, comprising a polyester containing 93 mol% or more of ethylene terephthalate as a component, and the face orientation coefficient, being 0.01 to less than 0.13, or a biaxially oriented polyester film to be formed into containers, comprising a polyester containing 95 mol% or more of ethylene terephthalate as a component, and the amorphous Young's modulus, being 120 to 220 kg/mm respectively suitable for containers, especially as a film on the inner and outer faces of metallic cans, since it is excellent not only in formability but also in impact resistance and taste property. ¢Formula 1! 140% S MD: Breaking elongation in the machine direction S TD: Breaking elongation in the transverse direction ¢Formula 2! ? S MD - S TD ?</p> |
