Hollow plastic sheets (corrugated plastic sheets) find applications across a wide range of industries-including electronics, packaging, machinery, light industry, postal services, food, pharmaceuticals, agrochemicals, home appliances, advertising, interior decoration, stationery, opto-magnetic technology, and biotechnology/healthcare-serving as a new type of eco-friendly packaging material. PP hollow sheets are a green, environmentally friendly material; while widely used internationally, their adoption in the domestic market is just beginning, where they are gradually replacing certain corrugated cardboard packaging materials. Some domestic enterprises are even developing them for use as architectural decoration materials. Due to their versatility and ease of use-often referred to as "Wantong Board" (universal board)-they are extensively utilized for advertising backdrops, stationery, industrial packaging, and product shock protection. Common examples include logistics totes, collapsible modular boxes, finished product shipping containers, and internal dividers. These sheets are typically manufactured from eco-friendly, recyclable thermoplastic resins such as polypropylene (PP) and high-density polyethylene (HDPE), along with various additives.
Additionally, there is a polycarbonate (PC) variant-known as "sunlight board" or PC hollow sheet-processed from high-performance engineering-grade PC resin. Characterized by high transparency, light weight, impact resistance, sound and heat insulation, flame retardancy, and aging resistance, this high-tech plastic sheet offers exceptional all-around performance and energy-saving, eco-friendly qualities, making it a widely adopted plastic construction material globally.
