A biaxially oriented polyester film capable of lining the interior and/or exterior of a container, including a polyester containing about 93 mol % or more of ethylene terephthalate. The film has a breaking elongation in the machine direction. (S MD) and the breaking elongation in the transverse direction (S TD), satisfying the relationships 140%≦(S MD+S TD)/2≦300% and |S MD−S TD|≦60%. The film is capable of lining the interior and/or exterior of food containers, especially on the inner and outer faces of metallic cans, since the film exhibits excellent formability, impact resistance and taste properties.
