Abstract
The present invention provides a transparent, dimensionally stable, biaxially oriented PLA film having a haze value of less than 3% and exhibiting strain induced crystallinity having been oriented by stretching the film from a substantially non-crystalline state by more than three times its original areal dimensions. The processes for making such films are also disclosed.
