Abstract: Polymeric multilayer material includes an adhesive layer having first and second opposed major surfaces. A first foam layer is joined to the first major surface and includes a first plurality of expandable microspheres. A first skin layer is attached to the first foam layer and is free of the first plurality expandable microspheres. A second foam layer is joined to the second major surface of the internal adhesive layer and includes a second plurality of expandable microspheres dispersed therein. A second skin layer is attached to the second foam layer and is free of the second plurality of expandable microspheres. A portion of the first expandable microspheres of the first foam layer and of the second foam layer is at least partially embedded within the adhesive layer. Embodiments, of polymeric multilayer materials described herein are useful, for example, as wearable medical or athletic support components. The materials can also be used as protective wrappings. For example, the materials can be wrapped around a sharp corner of an article, building, etc.

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.
