Abstract: A process for producing clear injection stretch blow molded containers comprising: I. molding a propylene polymer composition comprising: (A) a propylene polymer chosen from: (i) a homopolymer or minirandom copolymer of propylene containing up to 1.0 wt % of at least one of ethylene and C4-C10 ?-olefins; (ii) a random copolymer of propylene and at least one olefin chosen from ethylene and C4-C10 ?-olefins; and (iii) mixtures thereof, the propylene polymer having a melt flow rate of from about 1 to about 50; and (B) about 1 to about 1000 ppm, based on the weight of the propylene polymer, of at least one radiant heat absorbent; thereby forming a preform; and II. stretch blow molding the preform; wherein in step II, heat is supplied by infrared radiation, and the containers have a haze value less than 25.0%.

Abstract: Stretch blow molded containers comprising a propylene polymer composition produced with a metallocene catalyst, the propylene polymer composition comprising: A. 25.0 wt % to about 75.0 wt % of a homopolymer or minirandom copolymer of propylene containing up to 1.0 wt % of at least one of ethylene and C4-C10 ?-olefins, having an isotactic index greater that about 80%; and B. 25.0 wt % to about 75.0 wt % of a random copolymer of propylene and at least one olefin chosen from ethylene anti C4-C10 ?-olefins, containing about 0.3 to about 30 wt % of said olefin, and having an isotactic index greater than about 60%; wherein the propylene copolymer composition has a melt flow rate of 1 to 50 and a molecular weight distribution or less than 3.5.
