Which material is the right one?
High quality material processing
We see ourselves as a solution provider. Our customers can choose between polymer-based, bio-based and fiber-based materials for production.
Kiefel offers the right system for the manufacture of your products for every application.
Not everything that is supposedly green is also environmentally friendly. It is important to keep a close eye on the available materials and and to consider which material is best suited for the respective application.
Therefore, our Rethinking Approach applies here: We rethink your product from the ground up. Give us your product - we will design it sustainably and consider new approaches in terms of functionality, product design, material composition, as well as material selection - recycled, bio-based, natural fibers.
Furthermore, we adapt and redesign our process, machine and tooling technology.
Polymers
Polymerbased materials
Materials for processing e.g.:
- (Recycled) PET, PP, PS, PLA, PE
Food articles:
- Coffee, tea, beverages, baby food
- Bakery products, chocolate, ready meals, margarine
- Patisserie, delicatessen
- Fruits & vegetables, salad, eggs
- Meat, seafood, Pet food
Non-food articles:
- Medicine & pharmaceuticals
- Agriculture like flower pots
- Engineering & electronics, transportation
- Cosmetics
Biobased Materials
We have a wide range of materials in mind, such as biobased and biodegradable plastics as well as natural fibers, and test them for their applicability in our own laboratory. We are also very active in research.
We have already gained a lot of experience with PLA. Here, in cooperation with manufacturers of raw materials and additives, we have succeeded in increasing the temperature resistance so that biodegradable coffee cups can be produced from PLA on our machines.
Materials for processing e.g.:
- PLA, PHA, bio-PET
Natural Fibers
Renewable raw material
Materials for processing e.g.:
- CTMP (chemi-thermical mechanical pulp)
- NBSK (northern bleached softwood kraft)
- UKP (unbleached kraft pulp)
- ONP (old news print oder old news paper)
- OCC (old corrugated cardboard oder old corrugated containers)
- Some grades from annual plants
Application of primary fibers:
The result is sophisticated and visually high-quality packaging with uniform color gradients that meet the hygiene standards of the food, pharmaceutical and cosmetics industries.
- Food:
- Coffee, tea, drinks, baby food
- Cookies, ready meals
- Confectionery, delicatessen
- Salad
- High quality packaging of technology goods:
- Smartphones
- Pharmaceuticals
- Cosmetics industry
Application of secondary fibers:
Secondary fibers (packaging made from recovered paper) score in the field of protective packaging and agricultural products. Simple and functional packaging solutions are the result.
- Plant containers such as flower pots, seed trays
- Transport protection packaging for industrial goods
