Abstract: A polymeric composition comprising at least 95 wt. % of a metallocene-catalyzed polypropylene, and at least one of a clarifying agent or a nucleating agent is disclosed. The polymeric composition can have a lower haze value when compared with a second polymeric composition that has the same components in the same wt. % amounts as the polymeric composition except that the polypropylene in the second polymeric composition is a Ziegler-Natta catalyzed polypropylene. The haze values can be determined by ASTM D1003 at a thickness of 50 mils.
