Bosch Packaging Technology and swedish Billerud Korsnäs developed first sealed paper packaging. Instead of using polymer film, the 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. Swedish paper specialist contributed its expertise to the optimization of the mechanical properties of the paper, while Bosch Packaging 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. This 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 sustainable characteristics of the material increase its appeal to eco-conscious consumers. With the new paper, the swedish has developed a new, better packaging material which reliably withstands the stronger mechanical requirements in processing. With the ZAP-Module it is now possible to process mono-material paper on VFFS technology with dust-tight sealing.
