HP Embalagens is a major Brazilian packaging company serving world-renowned brands such as Nestlé, Ferrero Rocher, Natura, and Johnson & Johnson

Origin Materials, Inc. ("Origin") (NASDAQ:ORGN, ORGNW)), a technology company with a mission to enable the world's transition to sustainable materials, announced a strategic distributor relationship with HP Embalagens, a leader in high-performance thermoformed packaging, for sustainable PET bottlecaps.

HP Embalagens expects to purchase PET caps from Origin Materials for sale and distribution to its customer base, including many of the world's leading brands. The partnership brings together the Origin PET cap product portfolio, beginning with the 1881 beverage closure, and HP Embalagens' value-added distribution capabilities and market expertise in thermoformed products.

HP Embalagens is a leading packaging provider to South America and plans to distribute Origin PET caps to major customers in the region, with an emphasis on Brazil. The company specializes in thermoformed products and expects to leverage PET caps to expand its product catalogue and drive growth. HP Embalagens serves leading brands including Nestlé, Ferrero Rocher, Natura, and Johnson & Johnson.

Origin PET caps represent a technological breakthrough that can enable lighter packaging and better product barrier which improves shelf life. Unlike many injection molded or compression molded caps, Origin PET caps can be made with 100% post-consumer recycled material and used in food-grade applications.

Felipe Souza, HP Embalagens Purchasing and New Business Director, commented: "At HP Embalagens, our growth strategy centers on innovation, sustainability, and measurable impact. Our selection of Origin Materials to supply PET caps reflects our belief that consumers are ready for something new and better. The packaging industry has long sought a PET cap, and now Origin is making it a reality. We are thrilled to partner together to bring PET caps to our customers."

John Bissell, CEO of Origin Materials, commented: "We are excited to partner with HP Embalagens. Our strategic relationship immediately extends our market reach in South America, opening the door for significant growth in the region. We look forward to working together as we bring our PET caps to HP Embalagens' major customers."
