Shanghai Guangfa Paper Mill successfully produced high-strength, low-strength, low-strength corrugated base papers. The new product can prevent moisture from intruding into the corrugated base paper, suitable for product packaging that needs moisture protection, and is more suitable for food, fruits, vegetables, medicines and the like. The stiffness of the carton, the indicators of resistance to pressure puncture, and breakage resistance have been significantly improved. The physical performance indicators of the carton have exceeded the national corrugated paper standard after being inspected by the Shanghai Commercial Inspection Center and the Paper Testing Center. This product is the first in China, and its water absorption and permeability have reached the level of similar products in the world. The permeability of the moisture-proof corrugated paper in Indonesia was determined to be 180s, and the product was measured as 1800s. The surface water absorbency of APP's similar products in Indonesia's Jinguang Group is less than 75g/m2, while that of Taiwan's Zhenglong is less than 50g/m2, while the absorbency of this product is less than 50g/m2. At present, after being used by carton enterprises in Shanghai, Qingdao, and Changzhou, the product consistently reflects high quality and good moisture resistance. The product needs to add raw materials for chemical additives in the papermaking process, so the production cost is increased, and the price is higher than other high-strength corrugated stencils, and it is applicable to the middle-to-high-end export-oriented cartons that require moisture protection.
