From the perspective of market demand, the development of corrugated medium base papers in the direction of low quantification, high strength, and full specifications is a major trend. The demand for medium-strength, high-strength corrugated base papers is relatively large, and corrugated paper prices have risen. The quantification of corrugated paper in Beijing market is 127-180g/m2, and in the southern Guangdong and other places, 112-115 g/m2 original eucalyptus paper has been commonly produced and used, and the ring crush strength has been increased.
At present, reducing costs and reducing quantification are two major problems in the development of corrugated board: First, boxboard and corrugated base paper must be reduced in ration in order to ensure strength. With the development of high-speed and high-speed automatic corrugated paper production lines in China, higher requirements are placed on the quality of corrugated paper, so as to ensure the reliability of assembly line operations. Carton enterprises have used the corrugating medium's strength, length and length as indicators of production and operations. As an important indicator of sales and use, corrugated paper companies should strengthen inspections in this area. Second, make full use of cheaper and second-rate fiber raw materials. The basic composition of imported waste paper is wood pulp fiber raw material with good quality and less impurities. Due to the low price of waste paper in the international market, the price of imported waste paper is close to that of domestic waste paper. I think this is an opportunity for the development of high-strength corrugated medium paper. Corrugated paper production enterprises should make full use of imported waste paper, domestic waste paper and semi-chemical pulp, appropriately increase the proportion of imported waste paper, and enhance the role of chemical additives to produce better quality, low weight, high strength, and multiple specifications. The high-strength corrugated paper to meet the needs of the domestic market and create good economic and social benefits.
In the face of huge market demand, the author believes that relevant companies should fully seize the opportunity to work closely with the paper product packaging industry to develop mutual benefits, develop and produce low-quantity and high-strength corrugated paper to replace imported products, create their own brand, and increase product market share. rate.
Corrugated base paper is an important paper packaging material used to make corrugated board, and it occupies a considerable proportion in corrugated board. With the rapid development of the domestic paper products industry, the demand for corrugated base paper and kraft linerboard is continuously growing, and the development of corrugated paper is attracting attention. At present, the corrugated paper products market is promising, and many production enterprises have experienced phenomena of both production and sales. However, domestic high-strength corrugated papers cannot meet the demand for high-end export cartons, so imports from abroad are larger. According to customs statistics, in 2000 China imported 1.308 million tons of high-strength corrugated base paper. In recent years, its demand is steadily increasing. According to the analysis of the “15th Plan for Paper Industryâ€, the demand for corrugated paper in 2000 was 7 million tons, of which the demand for high-strength corrugated paper was 2.6 million tons, and the output of corrugated paper products was 5.5 million tons in the same period, of which 1.5 million tons were high-strength corrugated paper. . This shows that China's corrugated base paper, especially the high-strength corrugated base paper, is in short supply, and the gap is relatively large. The demand for corrugated base paper is shifting from middle-to-low to medium-to-high grade. The existing corrugated paper supply system based on middle- and low-grade products cannot meet the requirements of users for product quality. High-strength corrugated base papers rely heavily on imports. The formation of this situation is based on the author's analysis for the following reasons: (a) Due to the low added value of corrugated paper for a long period of time, papermaking companies that produce packaging paperboards are generally optimistic about the high added value and high demand of kraftliner and white paperboard. Due to the increase in the level of packaging of domestic paper products, the demand for domestic high-strength corrugated base paper and kraft linerboards has increased; (3) In the recent past, the international market for corrugated medium continues to be weak. Supply exceeds demand, while China's high-strength corrugated base paper market is seeking more than supply, just in contrast with the international market, resulting in more high-grade corrugated paper flowing to China, a huge paper consumer market. At present, many domestic companies are aware of the market demand for corrugated base paper and are making every effort to use domestic and international resources to improve the production capacity of corrugated base paper. According to reports, Guangdong Dongguan Nine Dragons Paper Co., Ltd. will invest 100 million U.S. dollars in a new project to produce 400,000 tons of corrugated paper and linerboard in 2001. The raw materials are imported waste paper. Shandong Linqing Yinhe Paper plans to use the semi-chemical straw and imported OCC to make high-strength corrugated base papers for the new 200,000-ton A-grade high-strength corrugated base paper project to make up for the shortcomings of domestic high-strength corrugated base papers and to replace imports.
