What is an extruder
and co-extruder upgrade?

The aim is to increase the production capacity of extruders by 20 to 30% and improve the thickness variation tolerances by 50 to 70%. Specific projects exist for mono and co-extruders as well as extruders for film with and without barrier. This upgrade is also intended for large extruder producing sheet and agricultural films.
