Cast film extrusion lines are commonly used to extrude plastic films especially for flexible packaging industry. / In a cast film extruder PE, PP or PA granulates (or other polymers) are melted inro an extruder and pushed through a flat extrusion die (T die), extruding a sheet of molten polymer onto a cooled roller (chill roll).
