    摘要： Provided is a polyester film containing a lubricant having an average particle diameter of 0.001 to 2.5 µm in an amount of 0.01 to 5.0% by weight and suited for the lamination onto the surface that comes in contact with the contents, of an easy-open can cap. The polyester film has a plain orientation coefficient of 0.115 to 0.140, two or more endothermic peaks in DSC curve in the range of 170 to 270°C, a peak temperature of 60 to 120°C of a complex elastic modulus (E'') in water and an intrinsic viscosity of 0.50 to 0.64 dl/g. Having these features, the polyester film laminated onto a metal sheet is excellent in can-capping processability and in corrosion resistance even after holding at high temperature.

    摘要： A film to be laminated onto a metal plate and molded, which comprises the first copolyester comprising ethylene-2,6-naphthalene dicarboxylate as a main recurring unit or a blend of the first copolyester and the second copolyester comprising ethylene terephthalate as a main recurring unit.
    Both the first copolyester and the blend contain diethylene glycol in an amount of 0.05 to 8 mol%. This film has a small water extraction of 0.5 mg/inch 2 or less and a center line surface roughness (Ra) of 4 to 30 nm.
    This film is excellent in moldability, retort resistance and taste retainability, does not spoil the taste of a refreshing drink and is also satisfactory in terms of handling property.
