A method for thermally welding an adhesive tape to a polymeric substrate wherein the backing of the adhesive tape enters into a cured physical connection with the polymeric substrate is disclosed. The adhesive tape is comprises a spunbonded backing that is coated, at least partially, on one side with a pressure sensitive adhesive, preferably natural rubber or acrylate. The spunbonded backing can comprise polyester or polypropylene fibers that do not melt during the welding process, and may optionally include additives such as pigments, UV stabilizers and flame retardants. |
