摘要： A masking film having improved wetting of substrates has an adhesion layer, a second layer, and optionally a core layer interposed between the adhesion layer and the second layer, wherein the adhesion layer comprises a blend of a metallocene polyolefin and a low density polyethylene and wherein the second layer provides increased stiffness, strength or mechanical properties to the film. The film may also include antistatic agents in at least one film layer.
