Abstract
An opaque or translucent molecularly oriented film made from a composition comprising at least one linear polyester (preferably polyethylene terephthalate) and 0.5-100% by weight based on polyester of at least one olefine polymer, wherein said composition contains at least one carboxylated polyolefine in an amount of 0.05-50% by weight based on olefine polymer. The composition used for the film is preferably formed by precompounding the olefine polymer and carboxylated olefine and then mixing with the polyester.
