1. A low-haze film, comprising an ethylene/propylene random copolymer composition comprising about 3.5-10 wt % ethylene content and about 90-96.5 wt % propylene content, wherein the percentage haze of the film, measured on a film of 2 mil thickness after 96 hours of annealing at 50° C., satisfies one of the following two criteria:
i) when the value calculated as
is about 0.002 or less, the percentage haze value is no more than about 3.3%; or
ii) when the value calculated as
is greater than about 0.002, the percentage haze value falls below the linear curve generated from the following equation:
where a is 3403.74 and b is 1.27;
wherein C2 is the ethylene weight percent of the total ethylene/propylene random copolymer, Xn,2i is the Regio error of the hexane extract, r1r2 is the Blockiness Index of hexane extract, and mmmm is the Meso-pentad of the hexane extract.
