Abstract: An article is described comprising a first film layer comprising polylactic acid polymer (semicrystalline polylactic acid polymer; amorphous polylactic acid polymer; or a mixture thereof); a second (e.g. polyvinyl acetate) polymer having a Tg of at least 25° C.; plasticizer. In some embodiment, the film layer further comprises inorganic pigment and/or hydrolysis stabilizer. In other embodiments, the film has a net melting endotherm, ΔHnm1, of less than 10 J/g. Also described are methods of making a graphic film.
