A multiple layer structure comprising a first and a second skin layer, each skin layer composed of a polypropylene containing polymer, and a radio frequency (“RF”) susceptible layer adhered to and between the first and second skin layers. The RF layer has a first component of a propylene based polymer, a second component of a non-propylene polyolefin, a third component of a radio frequency susceptible polymer, and a fourth component of a polymeric compatibilizing agent. |
