Abstract
The invention is directed to a composition suitable for high gloss air quenched blown films. The films are comprised of from 2 to 15 percent by weight of a substantially isotactic propylene-based copolymer having a melt flow rate of at least 5 g/10 minutes and having from 8 to 21 mole percent units derived from an alpha olefin; and from 85 to 98 percent by weight of an ethylene-based copolymer having a melt index of from 0.1 to 9 g/10 minutes. An air quenched blown film made from the inventive composition exhibits a value for gloss greater than the value for gloss exhibited by an air quenched blown film made solely from the ethylene-based copolymer.
