Corrugated board generally refers to hollow board (also called hollow grid board, Wantong board, corrugated board, double wall board). The English name is: pp plate sheet, which is a light weight (hollow structure), non-toxic, non-polluting, waterproof, Shockproof, anti-aging, corrosion-resistant, new material with rich colors. Compared with cardboard structural products, hollow board has the advantages of moisture resistance and corrosion resistance.

Compared with injection molding products, hollow panels have the advantages of shock resistance, flexible structure design, and no need to open injection molds. At the same time, the board can be flexibly added with anti-static and conductive masterbatches through the control of raw materials to produce plastic hollow boards with conductive and anti-static functions. The surface resistivity of the anti-static board can be controlled between 106 and 1011. The surface resistivity of the static conductive plate can be controlled between 103 and 105.

Application fields: hollow boards are mainly used in various industries such as electronics, packaging, machinery, light industry, postal services, food, medicine, pesticides, home appliances, advertising, decoration, stationery, optomagnetic technology, bioengineering medicine and health. It is a new type of environmentally friendly packaging material.

PP hollow board is a kind of green environmental protection material. It is widely used abroad. It has just started in China and gradually replaced some corrugated packaging materials. Now some domestic companies are also developing it for building decoration materials! PP hollow board is also called Wantong board because of its wide application and convenient use. It is widely used in advertising background, stationery materials, industrial packaging, product shockproof, etc. Our most common ones are turnover boxes, detachable combination boxes, and finished product packaging. Boxes and partitions in boxes, etc. The hollow board is generally made of environmentally friendly and pollution-free recyclable thermoplastic polypropylene (PP), polyethylene (HDPE) resin and various auxiliary materials. In addition, there is a polycarbonate (PC) hollow board, also known as the sun board, glass card Long board and PC hollow board are made of high-performance engineering plastic PC resin. They have the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame retardant, and anti-aging. Excellent performance, energy-saving and environment-friendly plastic sheet is the plastic building material commonly used in the world at present.
