(1) Upgrading sorting technology: Adopting more advanced spectral recognition (such as near-infrared NIR) and automated sorting equipment to improve the recognition accuracy of plastic types and reduce mixing issues, thereby enhancing the purity of recycled materials.

(2) Cleaning and decontamination process: Introduce efficient cleaning agents and physical decontamination techniques (such as ultrasonic cleaning) to remove surface contaminants such as ink and label adhesive, thereby enhancing the cleanliness of recycled materials.

(3) Refinement of crushing and screening: Through a multi-stage crushing and screening system, ensure uniform particle size of raw materials, enhancing the stability of subsequent melting and extrusion processes.

(4) Employing advanced blending modification techniques: significantly enhancing its processing performance and the mechanical properties of the final product, such as toughening modification, adding stabilizers, composite modification, etc.
