Abstract: Compositions and films are described comprising a polylactic (PLA) polymer and a copolymer comprising a first moiety comprising a C12-C30 alkyl group and a second moiety that is miscible in the composition. Suitable first moieties include a C12-C30 alkyl (meth)acrylate or a polyvinyl alcohol comprising pendent C12-C30 alkyl groups. Suitable second moieties include C1-C10 (meth)acrylic acid or ester thereof, vinyl acetate and ethylene vinyl acetate. The aforementioned composition may be used to form a release layer of an adhesive article such as a pressure sensitive adhesive tape. The films may be a monolithic film or a film layer of a multilayer film. The release layer may be disposed upon a substrate layer that may also comprise PLA. The films are produced by melt extrusion of the aforementioned composition and may be oriented.

Abstract: Containers (100), for example boxes, envelopes, mailers, and the like containing one or more deployable cushioning sheets (1500) are disclosed. The deployable cushioning sheets (1500) are connected to at least one wall of the containers (100) and can be deployed to be partially outside of the container for cushioning, for example by wrapping, an object (1600) to be packaged. The deployable cushioning sheets (1500) can contain, for example, paper, cardboard, foam, bubble film, or the like, or they can contain combinations of different types of materials. The containers (100) are useful in methods of packaging, storing, and shipping, among other uses.

Abstract: Compositions and films are described comprising a polylactic acid (PLA) polymer. The composition further comprises a copolymer comprising a long chain alkyl moiety. The copolymer further comprises a second moiety that is miscible in the polylactic acid polymer. In favored embodiments, the composition comprising the polylactic acid polymer and copolymer may be used to form a release layer of an adhesive article such as a pressure sensitive adhesive tape. The films may be a monolithic film or a film layer of a multilayer film. The release layer may be disposed upon a substrate layer. The substrate layer may also comprise polylactic acid polymer. The substrate layer may be coextruded with the release layer. In some favored embodiments, the film or film layer is oriented.
