    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 stretched polyester film for forming which comprises a polyester consisting mainly of ethylene terephthalate units and/or ethylene naphthalat e units, characterized by having a melting point of 180 to 270~C, a contact angle with water of 70 to 120~, and a coefficient of planar orientation of 0.08 to 0.15. The film has excellent releasability in repetitions of use, wh en used after forming, or even after use in a watery atmosphere, and has stable performances with reduced unevenness. The film is especially suitable for us e in metallic-can inside coating in which the film is laminated to a metal she et such as a steel or aluminum sheet and the laminate is formed into a can. In this application, the film is excellent in the releasability of the contents therefrom and combines heat resistance with processability.

    Abstract: A polyester film for thermal lamination characterized in that said film has a melting point of 150 - 250.degree.C, contains 0.01 - 1% by weight of diethylene glycol component and has an intrinsic viscosity ¢?! of not less than 0.7 is disclosed. This film has good formability and physical properties such as impact resistance, which are hitherto not attained, and the film is excellent in adhesiveness and taste characteristics, so that the film is suited as a wrapping material and as an inner liner of containers.
