<p>An adhesive tape for thermal welding on a polymeric substrate is disclosed. The adhesive tape comprises a spunbonded backing that is coated, at least partially, on one side with a pressure sensitive adhesive, preferably natural rubber or acrylate, wherein the adhesive includes fibers that do not melt in a thermal welding process. The spunbonded backing advantageously also contains polyester, preferably polyester and/or co-polyester fibers that have been surface-consolidated and/or embossed by a calender process. The composition of the tape disclosed herein provides for an especially sound physical connection when thermally welded to a wide variety of polymeric substrates.</p> |
