Plastic hollow board is a new material, which is made of resin or resin plus powder. It has the advantages of light weight, no pollution, corrosion resistance, waterproof and moisture-proof, high bearing strength, tear resistance and so on. The structure of PP hollow board is designed to be hollow, so it is also called hollow lattice board, corrugated board, double wall board and Wantong board. Hollow board has unique advantages. At present, it is widely used in packaging, advertising and decoration industries, and it has rich colors and good decorative effect.

At present, our group has three workshops, namely, new product production workshop, box making workshop and R&D workshop:

At present, the new product production workshop has three hollow plate production lines, which can produce various types of hollow plate plates with a thickness of 2-5mm and a weight of 300-1200 grams per square meter, with an annual capacity of more than 5000 tons. One of them is the hollow plate production line of the "one-step" production process, which is directly filled with talc powder. The addition amount of hollow plate powder is as high as 50%, which is the first production line in China to use talc powder to directly add resin to produce hollow plates, further expanding the new products of talc industry. The whole production process adopts the method of negative pressure suction feeding, 6 large closed material tanks for supply, and intelligent metering feeding by weight loss scale, which has the advantages of accurate feeding and arbitrary adjustment of the proportion of ingredients. The other two production lines are hollow plate production lines using the mixing process of powder master batch and resin.

At present, the box making workshop has a complete set of equipment including hollow plate prototype, die cutting machine, screen printing machine, high-speed double servo nail box machine and ultrasonic welding machine, which can produce various specifications of packaging boxes, turnover boxes, express boxes and other products required by the market. The annual production capacity is more than 10million.

At present, the R&D workshop has 3 experts in the plastic industry and 2 postgraduates majoring in plastics, equipped with advanced instruments and equipment. It has successively developed high whiteness masterbatch, high transparency masterbatch and high performance masterbatch, various special material products, various types of hollow plate products, and has more than 10 kinds of patented technologies, which has played an important role in extending the group's industrial chain.

We plan to continue to invest 15million yuan and add five production lines in the next few years, so that the annual production capacity of hollow plates can reach 15000 tons, and become the production base of hollow plates and the green demonstration plant of talc powder deep processing industry in Northeast China.
