ABSTRACT:
A film of biodegradable polylactic acid polymers and copolymers is produced by coextrusion which displays improved winding and manufacturability and end use performance. The film is coextruded from polylactic acid (PLA) polymers and copolymers and biaxially oriented. The surface layer(s) of the film is modified with a particle and displays improved COF, blocking resistance, reduced static generation, improved winding and improved package formation on packaging machines.
