Abstract: Disclosed is a polymeric composition containing at least 98 wt. % of a random ethylene polypropylene copolymer, 0 wt. % to 1.0 wt. % of an acid neutralizer, and 0.005 wt. % to 1.0 wt. % of a gamma nucleator (a γ-nucleator). The random ethylene polypropylene copolymer can include 0.5 wt. % to 12 wt. % of ethylene units and 88 wt. % to 99.5 wt. % of propylene units based on the total weight of the copolymer. The polymeric composition can have a haze value of less than 60% (as measured in accordance with ASTM D-1003, at a thickness of about 40 mils) and a crystallization temperature of more than 100° C. as measured by Differential Scanning Calorimetry. Articles containing the polymeric composition are also disclosed.
