The common PP/PS sheet extrusion production lines are single machine single-layer sheet production lines and double machine co extrusion three-layer sheet production lines. There are also multi machine co extrusion multi-layer production lines, which can process composite sheet production lines with up to 7-9 layers, such as high barrier EVOH multi-layer co extrusion sheets. This model can process polyolefin materials such as PP, PS, PE, etc.

Using multiple extruders co extrusion technology, we produce multi-layer co extruded composite PP and PS sheets, such as ABA, ABCBA, ABCDCBA and other multi-layer structures, which are widely used in thermoforming, printing, hardware packaging, electronic trays, flocking, food, clothing, tools, toys, stationery sheets, decorative sheets, etc.
*Equipped with precision distributor, uniform layering, adjustable proportion of each layer, and precise digital control.
*The inclined horizontal tablet structure makes operation and maintenance more convenient.
*The roller has independent power, and the linear speed is synchronized with the extruder speed through closed-loop control.
*The whole machine adopts PLC control to achieve automatic control of parameter setting, data calculation and feedback, alarm and other functions.
*GWELL independently developed an electronic control operating system.

Main uses of PP/PS sheet:
*PP/PS vacuum formed sheet
*PP/PS single-layer sheet, PP/PS co extruded dual color sheet, PP double-sided high transparency sheet, and other sheets used in the vacuum packaging industry.
*PP stationery sheet
*PP transparent sheet, frosted sheet (coarse sand, fine sand), two-color sheet and other sheets used in the stationery packaging industry.
