Company: Bosch Packaging Technology and BillerudKorsnäs


Equipment Snapshot: Prior to the launch of the world’s first Sealed Paper Packaging on a vertical form, fill and seal machine (VFFS) with the ZAP-Module in 2016, Bosch Packaging Technology and BillerudKorsnäs are bringing their latest innovations to interpack 2017. On display for sugar manufacturers will be the SVE 2520 ZAP, Bosch’s first continuous-motion VFFS machine now capable of producing dust-tight, sealed paper bags. Flour producers will benefit from the upgraded PME mandrel wheel machine with ZAP-Module

With the ZAP-Module from Bosch it is now possible to process mono-material paper on VFFS technology with dust-tight sealing. The secret lies in the characteristics of the Axello ZAP paper from BillerudKorsnäs, which was specially developed for this application, as well as in the ZAP-Module from Bosch Packaging Technology. Moreover, the ZAP-Module partially applies a minimal amount of the sealing agent during the packaging process enabling heat sealing of the paper on the VFFS machine. Now this new sealed paper packaging is also available for the mandrel wheel technology to improve the traditional paper bags produced on this type of machines by making them dust-tight. As a result, retailers and consumers profit from clean shelves, enhanced product protection from contamination and thus improved product quality.

The extension of the ZAP-Module to the first continuous-motion SVE machine offers manufacturers significant production flexibility and enhanced product safety. By producing different bag styles (pillow, gusseted or block bottom) with different packaging materials (both Axello ZAP mono-material paper and heat-sealable laminates) on the same machine, it enables manufacturers to enter new markets for dry food applications. In order to achieve a perfect dust-tight sealing, the machine is equipped with the ZAP-Module for heat sealing of the paper. Additionally, the machine combines a small footprint with a speed of up to 65 bags per minute. By adapting the gusseting and dosing unit, the solution ensures gentle material processing and high efficiency. Based on the proven SVE technology, the solution allows easy operation and maintenance, helping manufacturers to adjust quickly to evolving consumer demands.

The combination of the robust mandrel-wheel concept with the ZAP-Module allows for the production of tightly sealed paper bags protecting flour from external contamination. By offering additional functionalities, such as the inline weighing system and top-up dosing, customers benefit from the highest weight accuracy available on the market. The increased flexibility of the solution allows to produce a wide range of package sizes and formats on a single machine. Another advantage of this technology is the outstanding shape of the block bottom bag, with a gable or flat top, thanks to double bottom-pressing which helps in forming a hard, brick-like bag. While achieving an output of up to 100 packages per minute, the vibrating module shapes the bag and closes it keeping the air out, thus simplifying product compaction. This enables manufacturers to optimize their storage capacities and logistics processes, thereby reducing their environmental footprint.
