Abstract
A polyolefin woven fabric extrusion coating with superior soft tactile characteristic is disclosed comprising ethylenic elastomer and thermoplastic vulcanizate. The combination performs in a synergistic fashion to obtain more pleasing soft tactile characteristic than is available with either elastomer or thermoplastic vulcanizate alone. The inclusion of additives may enhance properties and include plastomer, UV stabilizers, flame retardant, antiblock, colorant, printable additives and polar additives.
