Abstract:
A method of making an adhesive tape comprising the steps of:a) providing a woven cloth with overlapping fibers and having a first side and a second side,b) extruding a polyethylene-based polymer onto said first side of said woven cloth at a temperature, rate and amount to embed the polymer into the cloth such that the overlapping fibers of the woven cloth are bound together but the polymer does not extend through to the second side of the cloth, andc) coating a pressure sensitive adhesive comprised of a blend of an acrylic and a thermoplastic elastomer, onto at least a portion of said polymer wherein said resulting adhesive tape is hand tearable in a substantially straight line without fraying and the unwind tension of a roll of the tape is less than 14 N/dm in the absence of a low adhesion backsize.
