Tetra Pak Extends Paper-Based Barrier to High-Speed Lines

Tetra Pak has extended its paper-based barrier technology to high-speed Tetra Pak A3/Speed filling lines, enabling aseptic carton packages with up to 87% renewable content for plant-based beverages.​

The solution replaces the traditional aluminium foil layer with an innovative paper-based barrier while maintaining equivalent food protection and shelf life. Maeil Dairies in South Korea became the first producer worldwide to implement this on an A3/Speed machine for soy milk packaging.​

Existing A3/Speed lines, capable of up to 24,000 packages per hour, can upgrade via a high-frequency induction-heating sealing system without major capital expenditure or production changes. This supports scalability for low-carbon packaging aligned with environmental targets.​

Tatiana Liceti, Executive Vice President of Packaging Solutions at Tetra Pak, emphasized scaling sustainable materials without compromising efficiency or cost competitiveness. The technology, first piloted in 2023, now enables industrial-scale deployment in Asia
