    Abstract: A biaxially oriented polyester film for use in producing containers comprises (1) a polyester containing 93 mol% or more of ethylene terephthalate units as a component, having a breaking elongation in the machine direction (S MD) and a breaking elongation in the transverse direction (S TD) satisfying ÄFormula 1Ü and ÄFormula 2Ü, or (2) a polyester containing 93 mol% or more of ethylene terephthalate units as a component and having a face orientation coefficient of from 0.01 to less than 0.13, or (3) a polyester containing 95 mol% or more of ethylene terephthalate units as a component and having an amorphous Young's modulus of from 120 to 220 kg/mm . Since the film has excellent formability, impact resistance and taste property, it is especially suitable as a film on both the inner and outer faces of metallic cans. S MD: Breaking elongation in the machine direction S TD: Breaking elongation in the transverse direction

    Abstract: A biaxially stretched polyester film for forming a container, characterized by being formed of a polyester substantially consisting of an ethylene terephthalate unit and an ethylene naphthalate unit, the refractive index in the direction of thickness of the film being 1.5 or greater. This film is not only excellent in the formability during formation into cans or the like, but has excellent properties in taste property, particularly, the taste property after the retorting, and may be suitably used for containers produced by forming process and, particularly, for metallic cans.

    Abstract: A film having a good adhesive property comprises a base film and a coated layer formed on at least one surface of the base film. The coated layer has carboxylic acid and primary groups such that, at a surface thereof, the concentration of the carboxylic acid groups is not less than 0.005 and the concentration of the primary amine groups is not less than 0.0015.

    Abstract: A biaxially oriented polyester film is suitable for laminating onto a metallic sheet so as to provide a laminate capable of being formed into a can. The polyester film comprises at least one of: (1) a polyester having a melting point of 246 to 280.degree.C and being such that when the laminate is formed into a can, then at a neck of the can the film provides an inner 1 to 3 .mu.m portion (a) close to the metallic sheet and an outer 1- 3 .mu.m portion (b) remote from the metallic sheet, which said portions (a) and (b) have respective average orientation intensity ratios, as measured by Raman spectrometry, of 6 or less and 8 or more; and (2) a polyester layer (A) of a polyester having at least 93 mol% thereof of units derived from ethylene terephthalate and/or ethylene naphthalate and a polyester layer (B) of a polyester containing an ionomer and which film has a face orientation factor of 0.10 to 0.15.
