    Abstract: 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 ?

    Abstract: Disclosed is a film having a good adhesive property comprising a base film and a coated layer formed on at least one surface of the base film. The coated layer comprises a mixture whose main constituents are a polyester resin and a melamine compound, and not less than 60% by weight of constituents forming the coated layer is the polyester resin. Or the concentration of a carboxylic acid of the surface of the coated layer is not less than 0.005 and the concentration of a primary amine of the surface of the coated layer is not less than 0.0015. The film having such a coated layer can indicate an excellent adhesive property for a deposited layer under a highmoisture condition, particularly, in water, and an excellent adhesive property for a printing ink.
