MULTILAYER POLYESTER FILM AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a multilayer polyester film which has high hydrolysis resistance and has high metallizability and printability to a film surface without occurring the problem of odor by evaporation of a hydrolysis-resistant agent.

SOLUTION: The multilayer polyester film comprises a base layer B comprising a polyester containing the hydrolysis-resistant agent and at least one outside layer A not containing the hydrolysis-resistant agent, in which the hydrolysis-resistant agent in the base layer B is an epoxidized alkyl ester of fatty acid, epoxidized fatty acid glyceride ester or its mixture.
