<p>The present invention relates to a polyester film for release film, which has a maximum height of projection (Rmax) in one surface (surface A) of said polyester film, of not more than 500 nm; and has a thickness variation defined by the following equation using the maximum, minimum and mean values of film thickness in the machine and transverse directions of said polyester film, of not more than 5%: <DF>Thickness variation (%) = (maximum thickness - minimum thickness) x 100/average thickness </DF></p> |
