摘要:
Disclosed is a polymeric composition that can include at least 95 wt. % of a polypropylene copolymer, and 50 ppm to 2000 ppm of an aryl amide containing clarifying agent, a phosphate ester salt containing clarifying agent, or a combination thereof. The polymeric composition can have a haze value of A after being extruded once and a haze value of B after being extruded 2 times, wherein the ratio of A to B is 1 to 1.35, wherein A is less than 25%, and wherein A and B are determined in accordance with ASTM D1003, at a thickness of about 40 mil.
