Abstract
This invention comprises a film useful as an adhesive, a composition useful to make the film, and a laminate comprising the film contiguous with at least one metal substrate, at least one foam substrate or combination thereof. The composition comprises (a) at least one anhydride grafted olefin polymer, (b) at least one high density polyethylene, and (c) at least one elastomer which preferably has a tensile elongation at break of at least about 585%, a density of at most about 0.900 g/cmor a combination thereof. The anhydride grafted olefin polymer or combination thereof is preferably present in an amount of from about 20 to about 40 weight percent, the high density polyethylene or combination thereof is preferably present in an amount of from about 40 to about 60 weight percent, and the elastomer or combination thereof is preferably present in an amount of from about 17 to about 30 weight percent. Each anhydride grafted olefin polymer is independently most preferably a maleic anhydride grafted high density polyethylene. The high density polyethylene preferably has a melt index at most about 30 dg/min. The elastomer is preferably a substantially linear ethylene polymer or olefin block copolymer.
