Explore Fiber Thermoforming

Natural fiber packaging

The wishes of customers are rarely as clearly stated as when it comes to packaging: sustainability is an essential component. Our modern thermoforming technology offers the possibility to process a wide range of materials. You can choose from classic, recyclable plastics such as rPET, bio-based materials including PLA or even natural fibers – Whatever your choice, Kiefel has the right machine, tool and automation solution for you.

The wide range of raw materials that can be used for this purpose in the field of natural fibers gives you full flexibility. You will not only receive a high-quality packaging, which is exactly tailored to your individual design wishes, but also a packaging solution that offers optimal protection for your product.

Unlimited flexibility thanks to natural fibers

Whether waterproof, biodegradable, or optimal product protection: With thermoforming all doors are open to your product ideas. From food to technical packaging, everything is possible.

Virgin fiber Virgin fibers or virgin pulp (e.g. CTMP, NBSK, UKP, ONP, OCC) are mainly used in the food sector. Here, certified materials are primarily used to ensure compliance with food industry regulations for paper packaging. High demands on appearance, quality (surface and edge geometries), strength and stable production processes are the top priorities.
Recycling fiber Recovered paper, such as paper and cardboard - previously dissolved in a water bath - form the primary material. However, these fibers can still be the basis for high-quality packaging, such as technical packaging, inlays and flower pots.
Alternative fibers and annual plants Here, for example, some varieties of annual plants, wheat straw pulp, bagasse or silphia are used. Due to the versatile fiber materials, there are extensive areas of application and high-quality primary as well as secondary packaging can be produced. Here, the focus lies on the idea of a circular economy and regional recycling.

Take a closer look with us

Expertise, research and development are the cornerstones of our work. Our Packaging Technology Centres as well as our Material R&D Centres are dedicated exclusively to the question of how we can optimise packaging and material. This knowledge can also be at your disposal.

A NATUREFORMER KFT can produce a variety of natural fibre packaging.
Processing procedures, cycles and process parameters are checked and optimised. This saves resources and guarantees a high output.
Real-life tests are used to put the products through their paces and check the previously defined requirements. Barrier properties, edge quality, stacking function etc. are checked before the final product is approved.
The material has to be dosed and weighed correctly according to the formula so that the required product is created in the end.
A fibre suspension or paper stock is produced from the inserted material using various technical modules (e.g. HP pulper, deflaker, pressure sorter).
The natural fibre pulp that is produced can be tested for consistency, flow behaviour in the fabric flow and the effects of the different additives.
Packaging Technology Center
The Packaging Technology Centers offer insights into the machine portfolio for the production of natural fibre but also plastic packaging. The natural fibres/fibres sector offers the NATUREPREP KFP series for the qualitative stock preparation of natural fibre pulp and the NATUREFORMER KFT series, on which various fibre products can be manufactured.
Material Center
The Material R&D Center is the starting point for product developments with our customers. Here, various natural fibres are researched, analysed, categorised and coating concepts for packaging made of natural fibres are designed. Afterwards, they are tested on pilot plants and optimised for the processing procedure.
