摘要

Injection stretch blow molded (ISBM) articles and methods of forming the same are described herein. The ISBM articles generally include a metallocene random propylene-based copolymer.

主权项

1. An injection stretch blow molded (ISBM) article comprising:
a metallocene random propylene-based copolymer in the absence of a clarifier, wherein the propylene-based copolymer has a melting point of from about 115° C. to about 175° C., microtacticity of from about 89% to 99%, and a molecular weight (Mw) of 170,000 to 210,000 and a recrystallization temperature of from 85 to 100° C., as measured by DSC.
