3 layers WINDMÖLLER & HÖLSCHER VAREX Blown film extrusion line

In a blown film extruder PE granulates (or other polymer) are melted in an extruder and pushed through a circular die extruding a tube of molten polymer. Tube is then inflated to multiples of its initial diameter and cooled to form a thin film. Bobble is later collapsed and re-winded.
