has launched the commercial production of PET caps at its manufacturing center in Reed City, Michigan.

“Achieving this milestone is a tremendous accomplishment, and we couldn’t be prouder,” says John Bissell, Origin CEO and Co-Founder. “Producing PET closures at commercial volumes, on the first Origin CapFormer System, in our production center in Michigan is just an awesome milestone in bringing our breakthrough caps to market.”

In February 2025, the company announced that three additional CapFormer lines were currently being built and tested, and were expected to complete their Factory Acceptance Tests in Q2. It also confirmed that it is still on schedule to have a total of eight CapFormer lines online by the end of 2025. Most of these systems will be used to produce its previously announced PCO 1881-compliant caps to fulfill the customer demand it is seeing for that cap format.

“This first CapFormer line is meeting all of our expectations and is expected to produce hundreds of millions of PET caps each year,” Bissell says. “We are continually improving our technologies and manufacturing process techniques so that future lines will have even higher production rates and even better unit economics. The sky is the limit as we begin to address the $65 billion closures opportunity.”

These PCO 1881-compliant caps are anticipated to be transformative for the packaging industry, finally unlocking the performance advantages and recycling circularity long promised by PET caps. Beyond the 1881 format, Origin says its technology platform for producing PET caps is uniquely positioned to improve the sustainability and performance of a wide variety of packaging solutions, both existing and new.

Origin says the CapFormer System enables 100% PET container-to-container beverage recycling for the first time. Its recent factory acceptance test demonstrated that the system performance met expectations.

The CapFormer’s manufacturing approach for PET closures combines thermoforming with slit-and-fold technology and proprietary design elements. According to Origin, the system can operate at high levels of efficiency while opening new design spaces for packaging.

“Market interest and the strength of the overall demand for our caps continues to suggest we will be able to sell every cap we can make,” Bissell says. “We have multiple MOUs signed, with a growing list of prospects in the qualification phase, and a growing pipeline of new potential customers. We’re looking forward to announcing additional MOUs along with customer names in the coming months.”

Bissell added: “We are excited for what’s to come. Our manufacturing team and production partners in Michigan, Reed City Group, have been doing excellent work. Looking ahead, we expect to ramp the production volume of line 1 over time and with additional CapFormer Systems being manufactured and tested concurrently with the startup of line 1. As previously indicated, we’ll be bringing additional CapFormer Systems on-line throughout 2025.”
