Colored corrugated plastic sheets are a new type of environmentally friendly material with the characteristics of lightweight, high strength, good weather resistance, corrosion resistance, and easy processing. It is a hollow sheet made of polypropylene plastic particles through high-temperature melting, extrusion, molding, and other processes. This kind of sheet can be made into colorful PP corrugated sheets of various colors by adding masterbatch of different colors or through other methods.
Corrugated plastic sheets are also known as corlfute boards, PP hollow sheets, correx boards, coroplast panels, polyflute sheets, impra boards, etc.
The manufacturing process of colored corrugated plastic boards includes the following steps:
Prepare raw materials: Polypropylene plastic particles are the main raw materials of pp flute board corrugated sheets. Before manufacturing, raw materials need to be quality-checked to ensure they meet relevant standards and requirements.
Melt extrusion: Put the polypropylene plastic particles into a high-temperature melting machine. After being melted at high temperatures, the molten plastic is extruded into sheets through the extruder.
Molding: After the extruded sheet plastic is cooled, it enters the molding machine for calendering and embossing to form a hollow structure.
Cutting: Cut the formed plate to a certain length for subsequent processing and packaging.
Inspection: Conduct quality inspection on the cut plates, including size, thickness, color, etc., to ensure that they meet relevant standards and requirements.
Packaging: Pack the inspected coroplast sheets for transportation and storage.
If you want to obtain brightly colored PP corrugated boards, you can choose to add different color masterbatch or use other dyeing methods to produce colored corrugated plastic sheets in various colors. When selecting suppliers, you need to ensure that their product quality and stability meet relevant standards and requirements. At the same time, customized production can be carried out according to actual needs to meet the needs of different customers.
