Abstract:
1. A multi-layer adhesive tape comprising: a) a backing formed from an oriented thermoplastic film, the backing having a first face and a second face; b) a primer layer adhered to the second face of the backing, the primer layer being adhered over only a partial area of the second face; c) a first release layer adhered to the primer layer over the entire-partial area, the first release layer also adhered to the thermoplastic film over a free area of the thermoplastic film to which the primer layer is not adhered, the first release layer adhering more strongly to the primer layer than to the thermoplastic film; d) a second release layer adhered to the first release layer over an entire surface area of the first release layer, the second release layer adhering more strongly to the first release layer than the first release layer adheres to the thermoplastic film; and e) a pressure-sensitive adhesive layer adhered directly or indirectly to the second release layer over an entire surface area of the second release layer, the pressure-sensitive adhesive layer adhering more strongly to the second release layer than the first release layer adheres to the thermoplastic film, and the pressure-sensitive adhesive, when adhered to a substrate, adhering more strongly to the substrate than the first release layer adheres to the thermoplastic film.
