摘要

The present invention relates to a multilayered polyester film comprising two or more layers obtained by the co-extrusion of polyester; being a multilayered film in which a skin layer or a core layer contains a UV absorber in an amount of between 0.1 and 5% by weight of the film as a whole, and which has a UV transmittance of less than 5% at 380 nm, and has a surface roughness (Ra) of no more than 10 nm.
