Abstract:
1. A film formed from a formed plastic comprising a poly(lactic acid) polymer composition comprising a mixture of a) a poly(lactic acid) polymer having a weight-average molecular weight M w of 50,000 or more exhibiting crystallinity, b) a poly(lactic acid) polymer having a weight-average molecular weight M w of 50,000 or more exhibiting no crystallinity and c) plasticizer comprising at least one poly(lactic acid) component with a number average molecular weight M n of 1200 or more per molecule and chemically bound to a polyester component, and wherein the film has a tensile modulus of elasticity of 100 to 1500 MPa and has an adhesion of 5 to 30 N/cm 2 .
