SIMULTANEOUSLY DRAWN OPAQUE FILM MADE OF PLA

摘要

The present invention relates to simultaneously drawn opaque biaxially oriented film made of at least one cycloolefin copolymer (COC) containing layer. The COC is preferably at a concentration of 0.5 to 30% by weight, based on the layer. The invention further relates to an opaque, biaxially oriented polyhydroxycarboxylic acid film containing at least one layer containing a polymer based on hydroxycarboxylic acids and a cycloolefin copolymer (COC). The invention further relates to a process for producing the PHC film and the use thereof.
