Abstract
The invention relates to a multi-layer structure in which one or more layers contain an acrylic polymer, and one or more layers contain biopolymers. The acrylic polymer and biopolymer could be in different layers of the structure, or in the same layer of the structure. The combination of acrylic polymer and biopolymer in the same multi-layer structure provides improved properties, such as improved adhesion, improved mechanical properties, and improvements in the ease of manufacturing. An inner layer containing a biopolymer gains significantly improved UV resistance, abrasion resistance, and surface appearance, when covered with an outer acrylic layer. The multi-layer structure may be in the form of a sheet, a film, a tube or pipe, or a profile, and could used by itself or as a cap-layer over another substrate.
