A new complete line for the co-extrusion of polypropylene sheet has been ordered from Union by a converter in the south of Italy. The line will be used to produce food wrap 950 mm wide with thickness ranging from 0.3 to 1.5 mm at a hourly production rate of over 1,000 kg.
The plant comprises two single-screw extruders configured to ensure excellent mixing and high productivity. The machines include a continuous flow automatic dual-platen screen changer, a 45°-inclined FI calender with Essair thickness control and cross-axis device to produce a sheet with optimal planarity and uniform thickness, automatic winders and devices for complete process automation.
All components have been optimized to enhance production efficiency, reduce energy consumption and prolong operating life. The line is controlled via an intuitive, interactive PC interface operating through a PLC to ensure ease of operation even by non-specialized operators.
