Sustainability is a driving force

At Kiefel we have made it our mission to produce packaging from renewable raw materials and thus create a sustainable alternative to plastic. By expanding our material expertise to include natural fibers, we are setting new standards in the packaging industry. We continuously rethink product design, functionality and material composition to develop packaging that can easily be integrated into the circular economy.


Fiber is the future. It is about treating our planet responsibly and creating sustainable solutions for future generations.

Stefan Julinek - former Head of Fiber Packaging

Technology & flexibility combined

Our thermoforming machines such as the NATUREFORMER KFT 90.1 offer:

  • Flexible production: Processes natural fibers such as pulp, CTMP, waste paper and annual plants such as silphium or miscanthus.
  • Product heights up to 120 mm and forming areas of 900 × 700 mm for a wide range of applications.
  • Fast tool change in just two hours – efficient and ergonomic.
  • Excellent energy efficiency and 30% more output.

Sustainability through local resources

The use of local raw materials not only reduces CO₂ emissions, but also allows for flexible material selection specifically for the production location. Raw materials from Sweden, Finland, France, Portugal, Austria and Germany offer a wide range of sustainable options.

Research & development with an entrepreneurial spirit

In the Material R&D Center, our specialists work on the further development of natural fibers and their possible applications. With innovations such as the combination of different technologies, the processing of natural fibers becomes possible for even more applications.
