Blownfilm lines, cast film lines, sheet extrusion and extrusion coating lines are all part of Reifenhäuser products. In 1911 Reifenhauser was founded as a forge. In the 1940’s the first extruder was introduced. In the years after Reifenhauser kept on innovating and inventing new solutions for the extrusion industry. In 2006 Reifenhäuser Extrusion  was founded. Today this Geman company has its own private technocology center for research and development.

Blown Film Extrusion
Blown film extrusion is the most common technology to produce plastic film. Blown film extrusion is typically carried out upwards vertically.
Film is made out of polymer material. These polymeres are generally in the form of granulate. This material is melted and then forced or extruded through a die. Air is blwon thourgh a hole in the center of the die. This pressure causes a bubble. This bubble is a thin layer of film. The film is pulled upwards from the die to cool down and winded on the a roll.
Blown film extrusion exists in various layers, the more layers the thicker the film.  The process with more layers is called coextrusion.
