Sustainable packaging concepts at FachPack

Bosch Packaging Technology presents new approaches for sustainable packaging

  • Use of monomaterials as primary packaging
  • Avoiding wastage in secondary cardboard packaging
  • Pearl – the new paper-based packaging concept

Nuremberg, Germany – In line with the main theme of the fair – environmentally friendly packaging – Bosch Packaging Technology will show visitors its innovative approaches in the area of sustainability at this year’s FachPack. “Sustainable packaging requires new solutions at a number of levels,” explains Torsten Sauer, project manager for sustainability at Bosch Packaging Technology. “We are developing and testing various approaches and are already implementing concrete projects with customers.” Primary packaging is mainly concerned with two aspects: the use of monomaterials in comparison to conventional films, and using paper packaging as an alternative to plastic. For secondary packaging, the focus is on both reducing packaging material waste and increasing the recyclability of packaging materials.

Trend towards monomaterials in primary packaging

Due to their good sealing ability, barrier characteristics and formability, films are currently indispensable for primary packaging. Flow wraps have established themselves as popular packaging for a wide range of products. “The trend is clearly towards monomaterials, which can be more easily and efficiently recycled, but are more difficult to process on packaging machines,” says Sauer. “The biggest challenge is the sealing of the films at high speeds. Here we are already achieving good results in tests on our horizontal flow wrapping machines.”

Paper packaging offers an alternative to flow wraps made of film. Yet, because the material is much stiffer than plastic films, folding at the transverse and longitudinal seams tends to be a challenge. In addition, at high speeds paper is more prone to tearing. Bosch is currently developing the optimum format part contours for paper forming, using systematic material and machine test series to do so. “Our goal is to manufacture product packagings that are completely free of cracks and wrinkles,” says Sauer. “We can already provide our customers with solutions for types of paper commonly used on the market.”

Even more sustainable secondary packaging

Secondary packaging made of paper and cardboard is sustainable per se because it consists of renewable and recyclable raw materials. Nevertheless, its full potential has not yet been exhausted. There are other ways of making production even more environmentally friendly, for example by avoiding packaging material loss during production. This can occur e.g. when packaging material cannot be processed due to quality considerations. Bosch already has systems that are capable of processing slightly bent or recycled cardboard. Consequently, what machines previously sorted out as rejects can now be used thanks to a larger tolerance range.

In addition, Bosch is working on an alternative to hotmelt gluing for paper and cardboard. “Hot glue is a challenge in the paper recycling process. In addition, it consistently leads to disruptions in the production process,” explains Sauer. “Ultrasonic sealing is a sustainable alternative. There is already considerable interest on the part of our customers, and we are currently running several pilot projects to implement this promising technology in real packaging.”

Pearl: the new paper-based packaging concept

With its Swedish cooperation partner BillerudKorsnäs, Bosch shows how uniquely formed and optimally sized shaped paper pods can contribute to a more sustainable future. Together, the companies have developed a new packaging concept called Pearl. It demonstrates the unique formability of the FibreForm® material (the leading 3D-formable paper on the market, patented by BillerudKorsnäs). The material is processed on Bosch machinery and paves the way for creative and sustainable paper packaging solutions.
