2107095 9217539 PCTABS00016 The present invention is directed to a novel polymer which in one embodiment, was formed by extruding an admixture (either a physical blend of solids, or a compounded melt) of a high molecular weight high density polyethylene (HMW-HDPE) resin and a high molecular weight low density polyethylene (HMW-LDPE) resin. Also disclosed is the direct reactor formation of this polymer. The new polymer can be used to manufacture high gloss, low haze films and to form easy to open bags. The present invention is also directed to a method of improving the haze properties of clear plastic films prepared from high molecular weight high density polyethylene (HMW-HDPE) resins, which method comprises adding a haze reducing amount of a high molecular weight low density polyethylene (HMW-LDPE) resin to said HMW-HDPE resins and forming films from the blended and extruded resin mixture.
