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.
Bosch and Swedish paper giant BillerudKorsnäs said that as a result, retailers and consumers profit from clean shelves, high product protection and improved product quality.
BillerudKorsnäs contributed its expertise to the optimization of the mechanical properties of the paper, while Bosch provided the 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 new solution combines this technology with the Axello ZAP paper from BillerudKorsnäs.
Compared to conventional paper, Axello ZAP is more durable, while retaining its natural paper characteristics and advantages from source to recycling.
Until now, the production of mono-material paper packaging was only possible with glued pre-made bags or formed paper bags on mandrel wheel technology.
With the ZAP-Module it is now possible to process mono-material paper on VFFS technology with dust-tight sealing.
Joachim Dittrich, head of Liquid Food product division at Bosch Packaging Technology, said: “This revolutionary concept would not have been implemented without the collaborative effort of both companies. Together we have developed a solution that will change the packaging market.”
The solution meets the growing demand for sustainable packaging for dry foods such as sugar, flour, grains and powders, and the machine allows versatile packaging styles, including pillow, gusseted and block bottom bags with gable or flat top closure. “We are positive that our solution, supported by several years of development, not only addresses today’s challenges for our customers but also gives them the possibility to enter completely new markets and areas of application using sustainable packaging,” said Marcus Velezmoro, sales responsible for the VFFS ZAP portfolio at Bosch Packaging Technology.
