A biaxially oriented polyester film to be formed into containers, comprising a polyester containing 93 mol% or more of ethlyene terephtlalate 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 mold or more of ethylene terephthalate as a component, and the amorphous Young's modulus, being 120 to 220 kg/mm2, is 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 + S TD) /2 <= 300% S MD: Breaking elongation in the machine direction S TD: Breaking elongation in the transverse direction [Formula 2] ¦S MD - S TD¦ <= 60%
