Correx Boards Gain Popularity in Construction and Advertising Sectors
October 18, 2025
Have you ever cringed at the scratches on your new floor or the stains on freshly painted walls during renovations or moving? These common headaches can now be easily avoided with a remarkable protective material – Correx board. This innovative product offers a simple yet effective way to safeguard your surfaces.
Correx board, also known as corrugated plastic sheet, twin-wall plastic, or PP corrugated board, is an extruded hollow sheet made from polypropylene (PP). Essentially, it's a plastic version of corrugated cardboard but significantly more durable, waterproof, and reusable.
The production of Correx board primarily relies on extrusion technology. The process begins with melting polypropylene pellets into liquid plastic. This molten material is then forced through a specialized die that creates the characteristic corrugated structure. As the plastic passes through the die, it forms two parallel flat sheets connected by vertical ribs, creating the hollow core structure.
After extrusion, the board undergoes cooling to maintain its shape and dimensions. Additional treatments like UV protection or flame retardant coatings may be applied for specific applications. Finally, the material is cut to required sizes, completing the manufacturing process.
