Tetra pak Its testing a paper plug for cardboard containers of Aneto vegetable broth, creating a package that contains 73% paper by weight and, if the plant-based polymers used in the coatings and the opening neck are included, 87% renewable content.
The brand has been selected for a controlled trial production of paper closures given the sales of its vegetable broth, combined with Aneto's already-made shift to sugarcane-derived polymers for its closures and coatings. It will be applied in a First pilot batch of family 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 collaborated 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%.
