Completely clear, stretch-blow molded polypropylene bottle, specifically for filling with paint, is obtained by biaxially orienting and blowing injection molded preform in stretch-blow molding plant

摘要

A novel, completely clear, stretch-blow molded polypropylene (PP) bottle, allowing detection of color of the bottle contents, is obtained by (a) forming a preform of oriented PP using an injection molding machine and injection mold, (b) conditioning over a heating profile and (c) biaxially orienting and blowing in a stretch-blow molding plant using a blow mold for plastics bottles.
