PureCycle and StackTeck Successfully Produce Living Hinge Cap Using PureFive Recycled Polypropylene

Collaboration Demonstrates High-Performance Functionality of PureFive® Resin in Demanding Caps & Closures Applications

ORLANDO, Fla., June 03, 2026 (GLOBE NEWSWIRE) -- PureCycle Technologies, Inc. (Nasdaq: PCT), a U.S.-based company revolutionizing plastic recycling, and StackTeck Systems Ltd., a global manufacturer of high volume injection molds and automation, today announced the successful production of a living hinge cap using up to 100% PureFive^® resin. The milestone demonstrates that post-consumer recycled (PCR) resin can meet the rigorous mechanical performance demands of one of packaging’s most technically challenging applications. The caps made with PureFive Ultra™ and PureFive Choice™ resins passed multiple customer-related tests, including the living hinge fatigue test.

Living hinges are among the most demanding applications in plastic part design, requiring a polymer to withstand hundreds of flex cycles without failure. Traditionally, virgin polypropylene has been required to achieve these performance standards. Through this collaboration, PureCycle and StackTeck have demonstrated that PureFive^® resin, produced through a dissolution recycling process, can deliver equivalent hinge performance. The caps dimensions were also within the tolerances of the same cap made with virgin resin. This unlocks a new category of sustainable packaging applications for brand owners seeking to incorporate recycled content without sacrificing functionality.

“At StackTeck, we are constantly working to advance what’s possible with injection molded plastics and sustainability is increasingly at the center of that work,” said John Rego, Senior Market Development Specialist. “Partnering with PureCycle on this living hinge cap is a testament to what industry collaboration can accomplish. PureFive^® resin processed beautifully in our tooling and the final part performance speaks for itself. We look forward to supporting converters and brand owners who want to bring this kind of sustainable innovation to market at scale.”

StackTeck’s precision tooling and deep expertise in caps and closures mold design were critical to optimizing processing conditions and part geometry for the recycled resin. The resulting cap successfully passed all required flex cycle testing, confirming its readiness for commercial packaging applications including food, beverage, personal care and household products.

“This achievement with StackTeck marks a significant step forward in demonstrating the versatility and performance of our PureFive^® resin,” said Pete Dias, PureCycle’s Senior Director of Market, Application and Product Development. “Living hinges represent one of the toughest tests for any polypropylene and the fact that we’ve proven our recycled resin is up to the challenge opens the door to a whole new set of packaging applications for our customers. We are proud to work alongside StackTeck’s world-class team to keep pushing the boundaries of what recycled content can achieve.”

PureCycle’s physical, dissolution recycling process transforms post-consumer polypropylene into PureFive^® resin by removing color, odor, additives and other impurities from the plastic. The resin performs similarly to virgin polypropylene and meets FDA standards for food-contact applications to enable the seamless integration into existing manufacturing processes. PureFive^® resin is also APR Certified for PCR Content, a requirement for many impending regulations across the United States.

Brand owners and converters interested in incorporating PureFive^® resin into living hinge or closures applications are encouraged to contact PureCycle to discuss trial opportunities.
