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).
