Plastipak rolls out PET oxygen barrier technology O2Blox

Plastipak has begun commercial rollout of O2Blox, a PET oxygen barrier technology designed to stay compatible with bottle-to-bottle PET recycling. Eckes-Granini Group is already using the technology for oxygen-sensitive products such as juice and functional beverages, with further customer projects in testing and validation.

Why this mattersA barrier layer that does not disrupt PET recycling streams could let brand owners meet EU recyclability and recycled-content rules for oxygen-sensitive products without switching packaging materials.

• O2Blox is Plastipak's new PET oxygen barrier technology aimed at products such as juice, ketchup and functional beverages.
• Eckes-Granini Group has already adopted the technology; several further customer projects are in testing and validation.
• O2Blox holds APR Design for Plastics Recyclability recognition and RecyClass Technology Approval.
• O2Blox is a finalist in the Circular Plastics category of the Sustainability Awards 2026, with winners due 11 November 2026 in Utrecht.
