Abstract:
A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25° C.; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.
