Abstract
A biaxially oriented laminate film including a core layer including a blend of crystalline polylactic acid polymer and an inorganic antiblock particle which is biaxially oriented at low transverse direction orientation temperatures to impart a degree of cavitation around the particles such that a matte or opaque appearance is obtained. The laminate film may further have additional layers such as a heat sealable layer disposed on one side of the core layer including an amorphous polylactic acid resin and/or a polylactic acid resin-containing layer disposed on the side of the core layer opposite the heat sealable layer, a metal layer, or combinations thereof.
