Abstract:
1. A polymer composition suitable for clear graphic cling film comprising a propylene-based composition, wherein the propylene-based composition has an melt flow rate in the range of from 2 and 8 g/10 minutes, a dynamic mechanical spectroscopy (DMS) value in the range of from 3700 to 10100 Pascal·second at 0.1 radian per second and from 650 to 1200 Pascal·second at 100 radian per second measured at 190° C., a crystallinity in the range of from at least 4 percent by weight to 11 percent by weight, a heat of fusion in the range of from 6 to 19 Joules/gram, and a DSC melting point of less than 110° C., and one or more alkyl phosphate-based release agent; and wherein the propylene-based composition comprises a first propylene/alpha-olefin copolymer that has a melt flow rate from 1 to 5 g/10 min, and a second propylene/alpha-olefin copolymer that has a melt flow rate from 5.1 to 12 g/10 min; and wherein when the propylene-based composition is formed into a clear graphic cling film having a 7 (±2) mils, the clear graphic cling film has a haze of less than 4 percent, measured according to ASTM-D 1003.
