PP/PS sheet extrusion machines

PP/PS sheets occupy a significant proportion in the fields of packaging and daily life applications. Compared with single-screw extruders, twin-screw extruders have inherent advantages when producing PP/PS sheets. Different sheet structure requires different extrusion structure, for example, transparent sheet is made by single extrusion machine, double-colors sheet is made by three extruders co-extrusion. If EVOH sheet (seven-layers structure of sheet), are manufactured by a 4-extruder co-extrusion line, and extremely strict proportion control of each layer's raw materials is required.
