Thank to the modularity of our machinery, it is possible to personalize each components according to the production needs. It is possible to equip the line with cast cylinders thermoregulated by diathermic oil for a higher speed of production and a reduction of the thickness of air bubble film produced. The forming cylinder is thermoregulated by a water thermoregulation unit in order to maintain more constant its temperature.
