Food approved extrusion

Our Superclean degassing technology can be integrated into all diamat extrusion lines and ensures that the materials can be manufactured in a food grade quality.

Smart and space-saving:
Super-Clean Process / Filtration

A system of different degassing sections provides the necessary material drying and deep cleaning required for food contact certification. The cascade structure ensures a large surface area of the melt, which allows the diffusion and dissolution of the volatile components and at the same time allows sufficient time for the plastics to remain in the extruder. At the same time, the space required by the system is kept as small as possible. An unbeatable advantage. In principle, the system can be integrated into all diamat extrusion lines.

Even with food contact certification, A-PET films are usually co-extruded into an ABA sandwich combination.

This usually involves co-extruding layers of 3 to 10% on top of the main layer. These layers are used to incorporate anti-blocking agents, which are generally dosed into the co-extruder in the form of master batches. For cost reasons, colours are also dosed and used on the co-extruder.

Recycling material and super-clean

Recycling material and super-clean

With our brand new developed and food certified extrusion line for recycled A-PET material, we have succeeded in reaching a new milestone in the development of lines for flat sheet extrusion.

Thanks to our intelligent line control, this new development is not only technically state-of-the-art, also flexible, cost-efficient, user-friendly and profitable.

Extrudable plastics

Our plastic extruder machines can mix components to the gram and melt them at exactly the right temperature.

Therefore our plastic extruders are able to extrude a large variety of plastics including:

  • polypropylene (PP)
  • polyethylene (PE, also known as polyethene or polymethylene)
  • high-density polyethylene (PE-HD)
  • polyurethane (PU or PUR)
  • thermoplastic polyurethane (TUR)
  • polystyrene (PS)
  • acrylonitrile butadiene styrene (ABS)
  • ethylene vinyl alcohol (EVOH)

and various polyesters like polyethylene terephthalate (PET – including recycled flakes) or amorphous PET (A-PET).
