en.Wedoany.com Reported - PureCycle Technologies, Inc., headquartered in Orlando, Florida, in collaboration with StackTeck Systems Ltd., based in Brampton, Ontario, has successfully produced a living hinge cap using up to 100% PureFive resin.
PureCycle states that its physical dissolution recycling process converts post-consumer polypropylene (PP) into PureFive resin by removing color, odor, additives, and other impurities from the plastic. This resin exhibits properties similar to virgin PP and meets the U.S. Food and Drug Administration (FDA) standards for food contact applications. The resin has also received APR certification for post-consumer recycled (PCR) content, which is required by many upcoming regulations in the United States.
The success of the living hinge cap demonstrates that PCR resin can meet the mechanical performance requirements of one of the most technically demanding applications in the packaging sector. Living hinges are among the most challenging applications in plastic part design, requiring the polymer to withstand hundreds of bending cycles without breaking. Caps made with PureFive Ultra and PureFive Choice resins passed multiple customer-relevant tests, including living hinge fatigue testing.
Traditionally, achieving these performance standards required virgin PP. PureFive resin, produced through PureCycle's dissolution recycling process, delivers equivalent hinge performance. The dimensions of the cap also fall within the tolerance range of the same cap made with virgin resin.
John Rego, Senior Market Development Specialist at StackTeck, stated that the company is committed to advancing the possibilities of injection-molded plastics, with sustainability increasingly at the core. Collaborating with PureCycle to develop this living hinge cap demonstrates what industry cooperation can achieve. The PureFive resin processes excellently in the mold, and the performance of the final part speaks for itself. Rego looks forward to supporting processors and brand owners who wish to bring this sustainable innovation to market.
PureCycle noted that StackTeck's precision molds and expertise in cap and closure mold design were critical in optimizing processing conditions and part geometry for the recycled resin. Passing all necessary bending cycle tests confirmed the resin's suitability for commercial packaging applications.
Pete Dias, Senior Director of Market, Application, and Product Development at PureCycle, said that this achievement with StackTeck marks a significant step forward in demonstrating the versatility and performance of PureFive resin. Living hinges represent one of the toughest tests for any polypropylene, and the recycled resin has proven it can meet this challenge, opening up a whole new set of packaging applications for customers. Dias also expressed pride in collaborating with StackTeck to continuously push the boundaries of what recycled materials can achieve.
