摘要： A blown film that comprises polypropylene that has a melt flow rate of 1.8 to 14.0 g/10 min. and a melting point of at least 115°C. The blown film has a haze of less than 10% and a gloss of greater than 70%. The blown film may be co-extruded with a medium density polyethylene or 15 wt% of an impact copolymer. A clarifier may also be incorporated. The blown film that comprises polypropylene is produced on a standard air cooled blown film line.

摘要： Polymer articles and processes of forming the same are described herein. The processes generally include providing an ethylene based polymer, blending the ethylene based polymer with a modifier to form modified polyethylene and forming the modified polyethylene into a polymer article, wherein the polymer article exhibits a haze that is at least about 10% less than a polymer article prepared, with a similarly modified polyethylene.
