PP Sheet Extrusion Line
Extruder —- Screen changer —–Melt pump —– T-die —— Calender —– Cooling bracket —– Haul-off—- winder
GWELL, a leading Chinese plastic extruder manufacturer, employs versatile co-extrusion technologies utilizing single, dual, or multiple extruders to manufacture composite PP sheets across diverse structural configurations. Our production capabilities span from single-layer and double-layer sheets to multi-layer composites, with predominant configurations including five-layer, seven-layer, and nine-layer architectures. These extruded sheets serve critical applications in thermoforming, printing, hardware packaging, and consumer goods industries such as food packaging, apparel, stationery, and toy manufacturing.
The extrusion systems feature adaptable configurations with either single-screw or parallel twin-screw extruders, delivering precise dimensional outputs:
-
Sheet width: 600mm to 1220mm
-
Thickness: 0.15mm to 3mm
-
Production capacity: 200kg/h to 1000kg/h
Engineered for operational reliability, the equipment ensures stable material feeding across diverse formulations while achieving superior raw material plasticization. This processing excellence guarantees enhanced sheet durability while eliminating downstream production challenges such as thermoforming defects, structural cracking, and chromatic inconsistencies.
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.
