Abstract
Abstract A bumper button or strip comprising (a) a rubbery cushion of oil-plasticized thermoplastic elastomer, (b) a dual-layer film, one layer of which is a polyolefin such as polyethylene fused to the rubbery cushion, the other layer of which is an oriented polyester polymer such as biaxially-oriented polyethylene terephthalate film, and (c) a pressure-sensitive adhesive layer adhered to the polyester polymer. The polyester polymer serves as a barrier to prevent migration of the plasticizing oil into the pressure-sensitive adhesive.
