Propylene random copolymer compositions are described herein. The compositions generally include a propylene random copolymer including from about 95.0 wt. % to about 99.0 wt. % propylene and from about 0.2 wt. % to about 0.8 wt. % ethylene, an additive selected from clarifiers, nucleators and combinations thereof and a stabilizer, wherein the propylene random copolymer exhibits a melt flow rate of from about 0.5 g/10 min. to about 4.0 g/10 min., a molecular weight distribution of from 5 to 10 and wherein the propylene random copolymer composition exhibits a flexural modulus of from about 180,000 psi to about 260,000 psi.

Mini-random copolymer resins having improved mechanical toughness and related properties suitable for thin wall thermoforming applications

A random copolymer having improved mechanical toughness and properties suitable for thin wall thermoforming applications is provided. The random copolymer exhibits the following physical properties: a flexural modulus profile having a 2% flexural modulus of about 168,000 psi, a 1% flexural modulus of about 190,000 psi, and a 0.4% flexural modulus of about 199,000 psi; a melt flow rate of at least about 2.0 g/10 min.; and a haze of less than about 40%. The random copolymer preferably comprises a copolymer of ethylene and propylene, wherein the ethylene content is in the range of from about 0.2% to about 0.8% ethylene by weight of the copolymer. The random copolymer also preferably includes a stabilizer and a clarifying agent such as a sorbitol based clarifier or a nucleator. Various articles of manufacture such as thermoformed containers and packaging may be formed from the random copolymer.
