Patent ID: 8207265

Claim:
An adhesive film comprising (a) from 20 to 40 weight percent of at least one anhydride grafted polyolefin, (b) from 40 to 60 weight percent of at least one HDPE having a density of from about 0.950 to about to about 0.965 g/cm 3 and (c) from 15 to 30 weight percent of at least one elastomer having a combination of a tensile elongation at break of at least about 585% as determined by the procedures of ASTM D822, and a density of at most about 0.900 g/cm 3 , wherein the elastomer is a substantially linear ethylene polymer or olefin block copolymer or combination thereof, together the anhydride grafted polyolefin, HDPE and elastomer or combination of each are at least 85 weight percent of the film, and the weight percentages are based on the weight of the polymers in the film.
