Abstract
A multiple layer structure comprising a skin layer composed of a polypropylene copolymer with styrene ethylene-butene styrene block copolymer within a range of 0-20% by weight skin layer, and, a radio frequency ("RF") susceptible layer adhered to the skin layer. The RF layer has a first component of a propylene based polymer, a second component of a nonpropylene polyolefin, a third component of a radio frequency susceptible polymer, and a fourth component of a polymeric compatibilizing agent.
