Abstract

The present invention refers to co-extrusion of one or more polyolefins with one or more adhesive layers to improve the adhesiveness of the polyolefins in metal, epoxy resin, glass, ceramics, paper, wood, thermoplastic resin, fabric, non-woven fabric, varnishes and formica. More specifically, the present invention refers to a method of co-extruding at least one polyolefin with an adhesive layer, thereby enhancing the adhesion properties of the polyolefin, particularly in polyurethane foams such that a polar surface is imparted to the obtained adhesived polyolefin.
