12 June,2016Bosch Packaging Technology, Waiblingen, Germany, and BillerudKorsnäs, Sweden, have developed the world's first Sealed Paper Packaging. Instead of using polymer film, a new solution enables production of dust tight packaging for dry products such as sugar, grains, flour, or powders using sustainable mono-material paper, which contains no additional polymer fractions. As a result, retailers and consumers profit from clean shelves, high product protection, and improved product quality. 

Paper specialist BillerudKorsnäs contributed its expertise to the optimization of the mechanical properties of the paper, while Bosch Packaging Technology proved its competence as a leading provider of packaging technology. The paper packaging is produced on the first vertical form, fill and seal machine (VFFS) with the so-called ZAP-Module. The module allows coating with the sealing agent on a minimal surface area, preserving the paper’s mono-material character. The solution is based on the proven "PME" machine concept from Bosch. The new solution combines this technology with the Axello®ZAP paper from BillerudKorsnäs.
