Tetra Pak is testing a paper cap for Aneto vegetable broth cartons , creating a package that contains 73% paper by weight and, if you include the plant-based polymers used in the coatings and opening neck, 87% renewable content.
The brand has been selected for a controlled trial production of paper caps due to the sales of its vegetable broth, coupled with Aneto's existing switch to sugarcane-derived polymers for its caps and coatings. This will be applied to an initial pilot batch of family-size packaging in Spain.
These tests will provide Tetra Pak with data on the cap's performance under real-life conditions and its resistance to moisture, temperature changes, and transportation, without affecting the quality of the broth. The company has already evaluated the integrity of the packaging, material strength, and recyclability in accordance with its standards and protocols.
Tetra Pak has partnered with Nissha Metallizing Solutions to replace the aluminum layer in aseptic packaging with a paper barrier from FSC-certified sources, which is expected to increase the paper content to up to 80%. If this solution is combined with plant-based polymers derived from sugarcane, the carbon footprint of aseptic food packaging could be reduced by up to 33%.
