PP Sheet Extrusion Line
Extruder —- Screen changer —–Melt pump —– T-die —— Calender —– Cooling bracket —– Haul-off—- winder
China plastic extruder manufacturer – GWELL can use single extruder, double extruder and multiple extruders co-extrusion technology to produce single-layer, double-layer or three-layer and multi-layer (mostly five-layer, seven-layer, nine-layer) co-extruded composite PP sheet, and can be widely used in thermoforming, printing, hardware packaging, food, clothing, stationery, toys, etc. Its main machine can adopt single screw extruder and parallel twin screw extruder, the production of sheet width up to 600mm-1220mm, thickness between 0.15mm-3mm, output up to 200kg/h-1000kg/h. It can feed stably under various formulas and have good plasticizing performance of raw materials, which not only ensures the toughness of the sheet, but also avoids the problems of thermoforming, cracking and uneven color in the later stage of the sheet.
PP sheet production line process principle
Plastic pellet – extruder: raw material melting and plasticization – quick change filter screen – extrusion die forming extrusion – three-roll calender – cooling setting device – trimming mechanism – traction conveyor – Shearing device or winding device
Production line composition
Screw extruder, screen changers, metering pumps and molds, three-roll calenders, cooling brackets, tractors, shears or winders.
Advantage
1. Equipped with precision distributor, uniform layering, adjustable proportion of each layer, digital precise control.
2. The temperature of the roller can be adjusted, and the surface gloss of the sheet is high.
3. High output, using oven, sheet is not easy to curl after cutting.
4. The whole line adopts man-machine interface display, and the whole machine adopts PLC control to realize automatic control of parameter setting, data calculation and feedback, alarm and other functions, and the management operation is more convenient.
5. Gwell independently writes the electronic control operating system.

Application
PP sheet can be made into various products through secondary processing forms such as thermoforming, mainly used for food, medicine, medical equipment and other packaging. Such as processed frozen boxes, dairy packaging boxes, fast food boxes, cold drink containers, trays, microwave utensils, etc. can be used for food packaging; Processing into blisters can be used for the packaging of solid preparations such as pharmaceutical tablets, capsules, etc. In foreign countries, especially in developed countries and regions, transparent PP sheet is widely used in food packaging and other fields.
