Abstract: A method of forming a graphic article is described such as a tape or sheet, comprising a PLA-based film. The PLA-based film comprises a semicrystalline polylactic acid polymer; a second polymer such as polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25° C.; and plasticizer. The graphic article is typically a tape or sheet that may further comprise a (e.g. pressure sensitive) adhesive and a low adhesion backsize or a release liner. The graphic article can be suitable for various end-uses.

Abstract: Films including solvent barriers and primer layers are described. In particular, films including a substrate, the substrate including polylactic acid, a primer layer disposed on the substrate, a barrier layer disposed on the surface of the primer layer opposite the substrate, and an adhesive layer disposed on a surface of the barrier layer opposite the primer layer. The barrier layer includes an amorphous aliphatic polyamide with a glass transition temperature of at least 40 #C. Such films can provide acceptable adhesion and barrier performance to polylactic acid based graphics film systems.
