BillerudKorsnäs’ busy and interesting stand at interpack was about new materials and solutions for paper-based sustainable packaging. Often this requires collaborations as shown by Bosch and BillerudKorsnäs in their joint development of sealable sacks for dry food goods and powders.
Together, the companies developed Sealed Paper Packaging made of BillerudKorsnäs’s Axello ZAP paper—the world’s first dust-tight, sealed paper packaging for products such as sugar, grains, flour and pasta. The solution is a combination of BillerudKorsnäs’s paper expertise and Bosch’s competence in packaging machinery. It is made of a mono-material paper, keeps retail shelves and pantries dust-free, while ensuring products remain tightly sealed and protected. The positive reaction of the market to the launch of Sealed Paper Packaging led to an extension of the ZAP-Module to more machines within Bosch portfolio, which were presented at its stand at interpack.
At its own stand, Billerud highlighted another collaborative development—a compostable flow pack that combines paper with a high-performance bio-coating that is ideal for food products such as nuts and snacks, confectionery and protein bars. The turnkey flow pack solution shown is a collaboration between BillerudKorsnäs, Walki and Eurosicma. The white high-contrast compostable substrate with barrier protection for dry food was provided by BillerudKorsnäs, the printing and converting by Espoo, Finland-based Walki Group and the flow packaging machine by Eurosicma Packaging Solutions of Segrate in Italy.
The raw materials used in the flow pack comply with the EN 13432 certification for compostability. In addition, the fiber formation and smooth surface allows for high quality printing with sharp detail and contrast. The barrier properties are in line with what is needed for a range of dry food applications and, of course, the pack is totally compostable.
Other collaborations such as the exciting FibreForm formed container solutions are provided by FreeFormPack, a joint venture between BillerudKorsnäs and Curti Costruzioni Meccaniche. These were shown at the Curti Costruzioni Meccaniche stand in Hall 15 at intepack. With the new inline packaging system, brand owners can simply integrate customized FibreForm packaging into their existing production process.
Composting is the process of breaking down organic waste by microbial digestion to create compost. Compost has many beneficial uses, including improving and fertilizing soil. To go through a composting process, organic waste requires the right level of heat, water and oxygen. In a pile of organic waste, there are millions of tiny microbes that consume the waste, transforming the organic materials into compost. In order to claim that a product
is fully compostable, the product has to meet all the requirements in the European Norm EN 13432 and/ or the US Standard ASTM D6400. Both specifications require that biodegradable/compostable products completely decompose in a composting setting in a specific time frame, leaving no harmful residues behind.
