O. Berk Company: Alternative to PET
A proprietary process that adds color to clarified polypropylene (PP) from O.Berk is a colorful alternative to stretch blow PET and provides the same glossy aesthetic at up to 80% less cost.
Benefits of the process include the ability to change design, shape or neck finish as a result of easier mold changes, and the option to incorporate a true handle or other unique design features. Clarified PP provides lightweighting opportunities because of its lower density and functions well as an alternative to PVC, with similar barrier properties. Because of its strength and flexibility, PP also possesses environmental stress cracking resistance properties and produces the least amount of greenhouse gases per thousand pounds in comparison to most other plastics, according to the company.
