Analysis on the current situation and prediction of paper and paperboard in the development

in recent years, printing technology has increasingly moved towards refinement, high-speed and automation. As the main printing consumables, paper has not stopped in terms of printing performance and new product development, and products have been launched continuously

⑴ development direction of printing culture paper

at present, printing paper is mainly letterpress paper, paper, offset paper, coated paper, etc. the quality of paper, offset paper and coated paper has been continuously improved in recent years. The domestic market of paper and offset paper has seen a situation that production exceeds sales. At the same time, the domestic market began to pay attention to some new products

① uncoated high-grade printing paper without ground wood pulp. At present, almost all uncoated printing papers without ground wood pulp are made by alkali method and a large number of calcium carbonate fillers are used. The performance of this kind of paper has been developing in the direction of brighter and whiter. The brightness of uncoated printing paper without ground wood pulp produced in Brazil, Europe and Asia in South America has reached 94o ~ 96O, and the whiteness is 150%. This kind of paper has not only good printability and higher optical properties, but also excellent imaging quality by inkjet, laser printing and electrostatic copying. American International Paper Corporation has announced that it will expand its patented color loktm technology from only producing HP trademark paper products to producing IP trademark paper products. Hewlett Packard also plans to sell this technology to other uncoated non wood pulp and paper mills

② alternative paper without wood pulp paper. Alternative paper without wood pulp paper generally uses mechanical wood pulp in large quantities, so that the electromechanical rotation can be realized at a continuous and adjustable speed, supplemented by fillers and light weight sizing, pressing and coating. The finished paper can replace the uncoated high-grade paper products for traditional purposes. Mechanical wood pulp can also increase the loose thickness of the paper. With the same paper thickness, the paper weight can be reduced by about 10%. The brightness of this alternative paper is equivalent to that of uncoated non wood pulp paper. Alternative paper products that have been launched include offset web paper of Abitibi company's alternative offset and equal offset brands, and bowhybrid brand printing paper of American Bowater company

③ coated offset paper (FCO paper) and metering sizing press light coated paper. This is a kind of high value-added paper, which is produced by the process of metering sizing, pressing, coating and heating soft calendering. The mechanical pulp content of the base paper used is high. Compared with uncoated super calendered paper (SC paper), FCO paper has better printability in thermosetting offset printing, which is more suitable for gravure printing, and can reflect excellent smoothness and gloss. FCO paper is replacing uncoated SC paper and LWC paper, especially when used as newspaper insert advertising and low price magazine paper

④ coating offset printing paper. The continuous development of thermosetting offset printing and the growth of postage have driven the market demand for ultra light weight coated paper (ulwc paper). At the same time, it is also a challenge to the paper's penetration resistance and opacity. In response to the growing demand for high-quality image printing, prepress and printing technology are developing towards the use of fine processing technology and fine printing

⑤ the prospect of digital printing paper is promising. As a new printing mode, digital printing is developing rapidly. Continuous wide width inkjet printing business growth and quality improvement (close to the offset level), from sheet fed to web expansion. It will be used in the printing field of newspapers and magazines, so a new kind of paper with cationic surface properties is needed

the continuous changes of direct mail advertising and financial media will bring the demand for new multi-functional paper. To realize preprint and variable data printing on high-speed printing production line, the paper used must have high-quality multi-color printing performance suitable for both offset printing and digital printing. At present, there is no paper that meets this demand in the market. This will be a market field that needs to be developed urgently and is expected to develop rapidly

⑵ development direction of packaging paper

among the four pillar packaging materials of paper, plastic, metal and glass, paper products have the fastest growth because of its cheapest price and recyclability. At present, the development trend of paper packaging materials in China is as follows

① high quality and lightweight packaging paper, paperboard and carton board. In order to make full use of resources and reduce the cost of mailing and transportation as much as possible, the production of low quantity paper, paperboard and packaging carton paperboard is the current development trend of paper products all over the world. China has put forward low quantity problems in paper, letterpress and offset printing paper, paper bag paper and so on, and has begun to solve them. High quality, light weight and variety diversification should also be achieved in products such as packaging paper and paperboard. In particular, the corrugated base paper and kraft liner paper with the largest consumption. According to the large demand for high-end packaging boxes in the domestic market, three low quantitative products should be added on the premise of appropriately improving the original product quality, that is, 100g/m2 varieties of corrugated base paper and 210g/m2 and 200g/m2 varieties of kraft board

② develop functional special cardboard for food packaging. At present, there is a single variety of Whiteboard in China, which is not classified to distinguish different packages, and there is no special food packaging board produced for the needs of different foods. In the future, functional special cardboard should be developed and produced for different food packages

③ developing plant fiber fast-food boxes, and developing fast-food boxes with straw, wheat straw, bagasse, bran shell and other crop fibers as raw materials have competitiveness and good economic and social benefits

④ develop natural green packaging materials. Natural plant fibers can be rolled or woven into packaging bags and boxes. After adding a little adhesive, it can be made into buffer packages of different shapes

⑤ develop special cardboard for disposable tableware based on straw pulp. Based on China's raw material resources, certain technology is adopted to ensure that its performance is close to the physical properties of wood pulp. The surface of the paperboard is treated for food packaging, so that the finished paperboard has the functions of hot water resistance, no leakage, no layering, oil resistance and heat sealing. This alternative to some paper products can alleviate the increasingly tense problem of pulp raw materials

⑥ develop and apply honeycomb paperboard. At present, the products include lsqi composite packaging box, lsoii full honeycomb cardboard packaging box and lsoii lined packaging box. Compared with the weight of corrugated boxes of the same specification, the paperboard can be saved by 60%. This new type of carton will become an ideal packaging for China's export commodities

⑦ develop and apply pulp molding. Product pulp molding is a three-dimensional papermaking technology. It takes waste paper as raw material and molds paper products with a certain shape on the molding machine. At present, it has developed rapidly

2. Development level

in recent years, China's paper industry has a strong growth momentum, with a basic balance between production and sales, and good overall benefits. The output and consumption of paper and paperboard have increased year by year. Since 2001, it has maintained the second position in the world after the United States, and has become a large country in the production and consumption of paper and paperboard. By the end of 2008, there were about 3500 paper-making enterprises across the country. While the output increased year by year, the products were developing towards high-grade and multi variety, and a number of paper-making enterprises with an annual capacity of one million tons emerged, such as Shandong Chenming, Jiangsu Jindong, Shandong Taiyang, Shandong Huatai, UPM Sichuan and other large enterprises

in recent years, the output of paper and paperboard has continued to rise. The operation of major industrial industries in 2008 released by the Ministry of industry and information technology shows that China's paper industry completed 83.9 million tons of machine-made paper and paperboard in 2008, an increase of 8.75% year-on-year. Among them, the output of paper reached 4.61 million tons, uncoated printing and writing paper 14 million tons, coated paper 4.5 million tons, light weight coated paper 1 million tons, white board paper 11 million tons, box board paper 15.5 million tons (the changes over the years are shown in Table 1). China's per capita paper consumption increased from 5.1 kg in 1978 to 64 kg in 2008 (see Table 2). In 2008, the import of paper and paperboard was 3.56 million tons, a year-on-year decrease of 11.24%. The import of paper and paperboard began to decline in 2005, with a decline of 14.58% in 2005, 15.84% in 2006 and 9.07% in 2007. The declining varieties include paper, writing and printing paper, kraft paper, corrugated paper, machine and instrument paper, wallpaper, tissue paper, paperboard, transfer paper, adhesive paper, etc. The increased varieties include toilet paper and cigarette paper. The export of paper and paperboard was 4.12 million tons, a year-on-year decrease of 13.47%. Among them, there are also declining varieties: paper, writing and printing paper, kraft paper, corrugated paper, handmade paper, cardboard, transfer paper, etc. The increased varieties include toilet paper, cigarette paper, machine and instrument paper, wallpaper, adhesive paper, etc

the sustained and rapid development of the papermaking industry stems from the new and expansion projects of China's papermaking industry in recent years. These projects have high technological starting points, advanced equipment, large-scale single machine production lines, high production concentration, and strong competitiveness in output and product quality. By absorbing foreign advanced papermaking technology and management experience, timely adjusting the industrial structure has improved China's papermaking technology and management level, as well as the quality and product grade of domestic paper, And the competitiveness of domestic paper in the international market

at present, the quality of domestic publishing and printing paper has been fundamentally improved. Its excellent cost performance has greatly attracted the publishing and printing industry, which has significantly improved the localization rate of printing paper in China's publishing and printing industry. At the same time, the output, quality and grade of domestic coated paper are also constantly improving, the varieties are increasing, and the market is also expanding. The survey shows that printing plants have been able to accept domestic coated paper completely, and are basically satisfied. The localization rate of coated paper for printing has exceeded 80%; It has contributed to the colorization and refinement of printed matter

II. Problems in development

as the consumption of paper and paperboard is closely related to economic growth, the decline in GDP growth will have an impact on the growth of consumption of paper and paperboard, which will also have a ductile thermal deformation Vicat tester of comparable materials. It is expected that the prosperity of the paper industry will continue to decline in the first half of 2009, and with the warming of the general environment in the second half of 2009, the problem rate of mixed loading of products will be reduced from 1% to 0.1%. Cultural paper is less affected by economic fluctuations, and its demand is relatively stable; The pressure of coated paper comes from the reduction of exports and the increase of production capacity; White cardboard fell most significantly due to the impact of new production capacity; It will take time for paper to get out of the trough; Boxboard is significantly affected by economic fluctuations, and the downturn will continue

on the other hand, most Chinese enterprises choose more foreign plastic extruder equipment. Except that the price of paper continues to rise, and the highest price in 2008 was 5600 yuan/ton (compared with 2007, the price per ton is almost increased by more than 1000 yuan, and the price in 2009 may fall to the level of 2007, or even lower), the prices of major paper types have fallen to varying degrees. Affected by the lower demand, coated paper also saw a decline of 300 ~ 600 yuan/ton, and even a decline of more than 800 yuan per ton; Cultural paper such as offset printing paper and light weight coated paper also fell by 200 ~ 300 yuan/ton respectively, and high-end offset printing paper even fell by 500 yuan/ton; As for the packaging paper and paperboard, the price of white paperboard and white paperboard fell sharply, with the price of white paperboard falling by 300 yuan/ton, while the price of white paperboard fell by 600 yuan/ton. According to the "light industry adjustment and revitalization plan" issued by the State Council in February 2009, if the export tax rebate rate is increased on a large scale, paper may obtain more space for export tax rebate. In response to the global financial crisis, the government will increase investment to stimulate domestic demand. It is expected that the demand for wrapping paper will increase significantly, and the consumption of cultural paper and household paper will also grow steadily with the economic recovery
