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.

Abstract: Provided are amorphous polyolefin compositions that can be dispensed digitally as the core in a core-sheath construction. These formulations provide dependable adhesion to both polar and non-polar surface in addition to providing a high barrier to air and moisture which is beneficial in many applications. These formulations and the method of processing these formulations provide many benefits, including low VOCs, avoiding die cutting, design flexibility, achieving intricate nonplanar bonding patterns, printing on thin and/or delicate substrates, and printing on an irregular and/or complex topography, no need for release liners or low-adhesion backsize, and no need for a post-processing step.
