Fiber Thermo­forming Natural Fiber Packaging 

We put your product first and rethink product design and functionality, material and composition towards a more sustainable product. Depending on that we adapt the manufacturing process and optimize machines and tools for your production. Your sustainable product can be recycled easier and together we are closing the loop.

You choose whether you want to use classic recyclable plastics like rPET, bio-based materials like PLA or natural fiber. 

This choice is more important than ever, as consumers tend towards sustainable packaging. Today Kiefel already offers you the solutions of tomorrow - thermoforming of natural fiber called Kiefel Fiber Thermoforming.

The Kiefel process - overview:

1. Raw Material: primary or secondary fibers
2. Fiber Preparation: refining with water to lower fiber concentration
3. Forming: the majority of the water is extracted from the fiber mixture through the forming tool via negative pressure
4. Pre-Pressing: continuous extraction of water, preformed product is pre-pressed and further drained with elastic tool 
5. Hot-Pressing: reduction of residual moisture to a minimum through pressure and heat, refinement of contours/engravings, handover to lifting conveyors
6. Quality inspection e.g. camera inspection systems (add-on)
7. Automation solutions e.g. sleeving, boxing (add-on)
