Graham Packaging has developed ThermaSet, a blow molded PET container for hot fill, pasteurized food. Consumer goods companies have been seeking a package that significantly reduces shipping, breakage and other manufacturing costs, and that responds to retailer requests for a more environmentally sustainable product with lower greenhouse gas emissions and a reduced carbon footprint. The innovative ThermaSet technology manipulates the morphology of PET, creating a container with properties far beyond those of standard PET: thermal stability above 300°F, 50% greater sidewall rigidity and a 25% increase in oxygen barrier. ThermaSet is a lighter weight, shatter resistant, drop-in replacement for glass on high temperature fill lines, allowing for the use of existing manufacturing assets while retaining the universally preferred metal lug closure which indicates quality and freshness. The reduced wall thickness results in a narrower jar that frees up valuable shelf space and provides the consumer with a safer package which is easier to handle, use and recycle. In fact, the jar is 100% recyclable as PET code 1. ThermaSet offers retailers and brand owners high-clarity, rigid plastic containers that remove breakage, downtime and cost along the supply chain, while increasing convenience for the consumer. This patented technology for shatter resistant, lightweight and eco-friendly PET jars which are a drop-in replacement to glass in hot fill and hold, pasteurized and retort applications deliver savings.
