4 Layers PP Plastic Sheet Extrusion Machine for Food Container with 800-1500mm Width and 0.2-1.5mm Thickness

PP Sheet Thermoforming Extrusion machine Used For Disposable Food Packing Container Long Life And High Output

1. Features of PP/PS sheet extrusion equipment

PP/PS sheet single-screw production line: PP/PS sheet single-screw extrusion line is the most mature and stable production solution at present. It generally adopts the form of single machine or double machine co-extrusion, and adopts technology to make this type of machine Comprehensive performance increased by 30%.

The PP sheet production machine produced by GWELL is mainly composed of feeder, single-screw extruder, mold, three-roll calender, mold temperature machine, cooling bracket, trimming machine, traction machine, shearing machine or rewinding machine. Machine composition.

There are many types of our PP/PS sheet production lines.We have PP/PS single-layer sheet production line and PP/PS multi-layer sheet production line.such as ABA, ABCBA, ABCDCBA and other multi-layer structure, which is widely used in heat forming, printing, hardware packaging, electronic tray, flocking, food, clothing, tools, toys, stationery pieces, decorative pieces and so on.

2 . Introduce of PP/PS Sheet production line

PP/PS sheet extrusion production line is common for single-extruder single-layer sheet production line and double-extruder co-extrusion three-layer sheet production line. There are also multi-extruder co-extrusion multi-layer production line, which can process 7-9 layers of composite sheet at most, such as high-barrier EVOH multi-layer co-extrusion production line. This type of extrusion line can process PP, PS, PE and other polyolefin materials.
