Flat film extrusion

Most of our films (wall thickness < approx.1.5mm) and sheets (wall thickness > approx. 1.5mm) are manufactured by Extrusion. We offer the production of single-layer monofilms and multi-layer coex films as standard.

Currently we cover a range from 0.025 (25 µm) to 30mm thickness and up to a width of 1,700mm at our production locations with more than 20 extruder lines in operation.

  • Calendaring process

    In the calendaring process the polymer melt is calibrated between two calendar rolls. This way, high-quality embossing structures (embossed foils) are produced, along with high-gloss, highly transparent or matte standard surfaces depending on surface structure of the rolls.

  • Cast process

    Thinner films (<0.15mm resp. 150μm) are manufactured in the cast process. In this process, the melt film is only applied to one side onto a cooled roll and congeals to a proportionally thin film.

  • Clean Room

    For many applications (especially optics, FIM films, protection films, design, decor, etc.) manufacturing of films in flawless quality that is almost free of specks is absolutely essential!

    Besides selecting our raw materials accordingly, we ensure these stringent standards are met by operating a number of our extrusion lines in a secluded clean room that can only be accessed via sluice systems. This way, clean room conditions are preserved and the impeccable surface quality of these films is warranted!

  • Sleeve technology

    In the scope of the sleeve technology, in contrast to the calendaring process or the cast process, BOTH sides of the film are in contact with the defined steel surfaces over a longer period of time, which creates optimal cooling conditions. This is achieved via a chilling roll on the one side and a steel band on the other side. This way, we manufacture High Performance Films of the highest of technical Standards! 

  • Extrusion laminating, lamination

    In this process, the melt strip is brought into contact with a composite material immediately upon expulsion from the flat nozzle. This continuously produced film composite is exclusively cooled and calibrated in the calendar.

    The composite materials used may be fleeces, fabrics made up of various fibers (polyester, glass, carbon, etc.) or webs made of plastics or metal.

    The composite material can be used on one side, both sides or as core layer. The application of fleeces or fabrics has an influence on mechanical properties such as rigidity or elasticity. With fleeces, the adhesive strength and the adhesive properties regarding other substrates is significantly improved. Among other things, laminated films can also be used to achieve decorative effects. Of course lamination of similar composites can also be carried out in the roll-to-roll process.


  • Sandwich-Composite panels

    For LAMINAEX sandwich-composite panels we have developed and perfected a special type of extrusion laminating. In this process, cover layers of film, GMT materials or aluminium sheets are fed onto an extruded foam core and calibrated in a double-belt press and cooled.

    In this manner, sandwich panels up to a width of 1,370mm and a thickness of 30mm are manufactured in a continuous process.

  • Foam extrusion

    Thanks to our know-how in manufacturing sandwich panels we also have a wealth of experience in foam extrusion. Afoaming agent added to the polymer melt, causing it to foam up after exiting the nozzle.The closed-cell cavities that are thus created in the plastic matrix greatly reduce the specific weight of the sheet, which is of special significance for sandwich cores.
