description	In one embodiment, a film is described comprising a mixture of semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) midpoint as measured by differential scanning calorimetry of at least 25° C.; and plasticizer; wherein the film is oriented. In another embodiment, a film is described comprising a mixture comprising semicrystalline polylactic acid polymer, polymer having a midpoint Tg as measured by differential scanning calorimetry of at least 25° C., and plasticizer; wherein the mixture exhibits a single midpoint Tg and the single midpoint Tg ranges from 40° C. to 65° C.; and wherein the film is oriented and the oriented film exhibits a higher midpoint Tg ranging from 40° C. to 65° C. and a lower midpoint Tg ranging from 5 to 25° C.
