摘要：
A plant and a process for producing a plastic stretch film are described. The plant comprises one or more extruders which feed a flat extrusion head and deposit the melted plastic material on a chill roll. The plant further comprises a vacuum box arranged near the flat extrusion head and a control unit equipped with a memory and programmed to regulate the production parameters of the plastic stretch film, and a mobile temperature sensor arranged in a fixed angular position with respect to the flat extrusion head. The control unit is programmed to regulate the depression generated by the vacuum box at least depending on the temperature detected by the mobile temperature sensor.
