    摘要： The present invention provides a multiple layered non-PVC containing tubing structure. The tubing structure has a first and a second layer. The first layer is of a polymer blend of (a) from about 30% to about 50% by weight of the first layer a first polyolefin selected from the group consisting of a first propylene containing polymer, (b) from about 0 to about 50% by weight of the first layer a second polyolefin of an α-olefin containing polymer; (c) from about 0% to about 40% by weight of the first layer a radio frequency susceptible polymer and (d) from about 5% to about 40% of a first thermoplastic elastomer. The second layer is attached to the first layer and includes a non-PVC containing material.
