Abstract

A tape wrap system adapted for protecting tubular articles comprising an innerwrap covering the surface of the article to be protected and an outerwrap placed over said innerwrap, said innerwrap comprising an impact-resistance polyolefin layer carrying an adhesive layer on its inner surface and a layer comprising an heat fusible material on its outer surface, or a single layer comprising a blend of an impact resistant moiety and a heat fusible moiety carrying an adhesive layer on its inner surface, said outerwrap comprising an impact-resistant polyolefin layer having an heat fusible layer on both surfaces or the inner surface thereof, or a singular layer comprising a blend of an impact resistant moiety and a heat fusible moiety; said tape wrap system fusing said innerwrap and outerwrap together when heated and thereafter cooled.
