Abstract
The invention relates to a multi-layer structure having at least one inner layer containing an alloy of a biopolymer and an acrylic polymer and at least one outer layer containing a thermoplastic or thermoset polar polymer matrix. The combination of outer polar layer and an inner biopolymer/acrylic layer provides improved properties, such as improved adhesion, and improved mechanical properties. The multi-layer structure may be in the form of a sheet, a film, a tube or pipe, or a profile, and could be used by itself or as a cap-layer over a substrate.
