Tetra Pak, in collaboration with Sterilgarda Alimenti, has introduced a 1-litre aseptic carton featuring a paper-based barrier, marking a development in carton packaging materials aimed at increasing renewable content.
The new barrier is integrated into the Tetra Brik Aseptic 1000 Edge carton, a widely used format. When combined with plant-based polymers, the package achieves a renewable content level of 90%. The structure is designed for ambient distribution and is reported to deliver shelf life and performance comparable to conventional aseptic cartons that use aluminium foil barriers.
According to the Carbon Trust, the new configuration can reduce the carbon footprint of the package by up to 50% compared with traditional structures. The material structure has also been simplified, moving from three primary materials to two—paper and polymers.
Giampaolo Rossi, Plant Director at Sterilgarda Alimenti, said: “We at Sterilgarda Alimenti stand for tradition and innovation. Through our continuous improvements in technology and product quality, we aim to provide the best possible answers to evolving consumer needs. Conscious consumption is becoming increasingly important, which is why adopting pioneering technologies is key across all our activities. Tetra Pak’s new paper-based barrier is a groundbreaking innovation in beverage packaging and represents a significant contribution to our journey towards greater sustainability.”
Tatiana Liceti, Executive Vice President, Packaging Solutions at Tetra Pak, added: “As environmental sustainability continues to shape the food and beverage industry, this innovation is an important step forward. It introduces a new barrier material that helps producers move closer to their environmental goals.”
The paper-based barrier was first introduced in 2023 for portion packs and later adapted for high-speed lines. Tetra Pak is also investing in further development, including a €60 million pilot plant in Lund, Sweden, and plans to invest approximately €100 million annually through to 2030 in related packaging technologies.
