Foil extrusion
Plastic film extrusion is a manufacturing process that extrudes a thin layer of plastic into a continuous sheet of film. This process has revolutionised the packaging industry and provides a cost-effective and efficient solution for a wide range of applications.
Foil plays an important role in everyday life. Among others, in the household as in the transport sector, the use of plastic film is crucial and unavoidable. The two variants of film production are blown film extrusion and flat film or sheet extrusion.
The plastic material, which can be made of different polymers such as polyethylene or polypropylene, is melted in an oven and then passed through a series of rollers that gradually flatten and stretch it into a thin sheet. The sheet is then cooled and wound onto a coil for use in various applications.
One of the main advantages of plastic film extrusion is its versatility. Manufacturers can adjust the thickness, width and length of the film to suit the needs of specific applications. Plastic film is commonly used in the food packaging industry, where it provides a barrier against moisture and oxygen to help preserve the freshness and flavour of food products. It is also used in the medical industry for packaging and sterilisation purposes, as well as in the construction industry for insulation and vapour barriers.
Types of film extrusion at Plastima
As exclusive partner of SML and Collin Lab & Pilot Solutions, Plastima supplies turn-key solutions for lab and pilot scale for foils as well as large-scale production lines for flat film and sheet extrusion within the Benelux.
To support the production process, Plastima also supplies complex inspection systems for surface and defect analyses. Using these analyses, film quality can be guaranteed and improved.

Plastima has exclusive partners when it comes to blow films. In blown film design, the interaction of die opening, output speed, inflation ratio and rewinding speed is important. The die opening is fixed by the die insert and the blow-up ratio is determined by the product needs. Some moulds have automatic adjustments. Internal air pressure must also be kept stable to ensure uniform thickness. For questions surrounding blowing film, Plastima is also the right place to go. We can therefore supply a total package of high-quality machines for blown film processes.
