Abstract

A graphic article comprising a Poly lactic acid (PLA) based film and in particular, an ink layer depicting a graphic is described. The PLA based film comprises a semicrystalline polylactic acid polymer, a second of a polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25° C., and plasticizer. The article is typically a tape or sheet that may further comprise an adhesive (e.g. pressure sensitive) and a low adhesion backsize or a release liner. A method of forming a graphic article using the film of the invention is also disclosed.
