POLYMERIC FILMS COMPRISING BIODEGRADABLE POLYESTER OR COPOLYMER THEREOF

摘要

The presently disclosed subject matter is directed to a film comprising a blend of about 90% to 99% polyester and about 1 % to 10% biodegradable aliphatic or aromatic polyester (by weight). It has been surprisingly discovered that polymeric films comprising the disclosed blend exhibit improved flexibility and impact strength compared to polyester films known in the art. Films with the disclosed blends also advantageously do not adversely affect recyclability of the film. The disclosed films can be used in a wide variety of areas, including (but not limited to) shrink sleeve applications.
