发明名称 PROCESS TO PRODUCE BIAXIALLY ORIENTED POLYLACTIC ACID FILM AT HIGH TRANSVERSE ORIENTATION RATES
摘要 A biaxially oriented laminate film including a first amorphous polylactic acid polymer heat sealable resin layer and a second core layer including a blend of crystalline polylactic acid polymer and 2-10 wt % of the core layer of an ethylene-acrylate copolymer. The laminate film, exhibiting the property to be transverse oriented in excess of 6 times its original width, typically 8 to 10 times its original width with excellent operability and relatively low haze, is disclosed. The laminate film may further have additional layers such as a third polylactic acid resin-containing layer disposed on the side of the core layer opposite the heat sealable layer, a metal layer, or combinations thereof.
