Double-screw PP Sheet Extrusion Production Line SWT-75s is engineered to process both virgin PP pellets and recycled scrap materials simultaneously. For cup manufacturing plants generating edge trim and waste, this system reprocesses in-house scrap back into high-quality sheet, feeding directly to your thermoforming lines. The twin-screw configuration ensures excellent mixing, stable melt consistency, and uniform thickness across the entire sheet. It reduces raw material costs, minimizes waste disposal, and secures a stable supply of sheet—all while maintaining product quality. An efficient, cost-saving solution for sustainable in-house recycling and continuous production.

Scope Of Application
Twin-screw extruders are capable of processing a wide range of materials—such as PP, PET, and PLA—while effectively preserving their inherent properties. Their unique screw design exerts low shear force during the plasticization process, thereby preventing damage to the material’s molecular structure. The resulting sheets feature high transparency, excellent toughness, and precise thickness tolerances, making them an ideal choice for thermoformed packaging, food containers, and various industrial applications.
PP sheet offers excellent chemical resistance, good heat resistance, and outstanding mechanical strength. It is lightweight, non-toxic, and odorless, meeting safety standards for direct food contact. Thanks to its superior toughness and high impact resistance, PP sheet performs exceptionally well in both cold-fill and hot-fill applications. Furthermore, it is fully recyclable and environmentally friendly. As a versatile thermoforming material, PP is widely used in sectors such as food containers, beverage cups, medical packaging, industrial components, and automotive parts. Its excellent tensile properties and transparency (in high-clarity grades) make it an ideal choice for deep-draw thermoformed products.
