SELF-ADHERING TAPE COMPRISING MULTILAYERS OF POLYOLEFIN POLYMER MATERIALS AND METHOD

摘要

A self-adhering tape is described comprising a substrate layer having a first major surface and opposing major surface; an adhesive layer disposed on the first major surface of the polyolefin substrate, the adhesive layer comprising a polyolefin polymer and optionally further comprising a tackifying resin; an outer layer disposed on the opposing major surface of the polyolefin substrate, the outer layer comprising a polymer comprising at least 50 wt-% C2-C3 alkylene and at least 20 wt-% C4-C20 α-olefin. The self-adhering tape is suitable for use as a grip tape or an electrical tape. Methods of making and using the tape are also described.
