Abstract
The invention relates to polymer tapes that are blends including at least one silane-grafted single-site initiated polyolefin resin. The silane-grafted single-site initiated polyolefin resin generally is a copolymer of ethylene and a C3-C20 alpha-olefin that has a molecular weight distribution between about 1.5 and about 3.5. The polymer tapes include an adhesive on at least one face of the polymer. The polymer tapes can be foamed.
