ABSTRACT:
A surface of the thermoplastic polyester film which has stickiness after having been heated is treated with a monocarboxylic acid so as to convert hydroxyl groups on the film surface into corresponding ester groups by reaction with the acid. Further, the film surface is treated with a monohydric alcohol so as to convert carboxyl groups on the film surface into corresponding ester groups by reaction with the alcohol. Thus, the stickiness on the film surface is eliminated.
