The correlation between papermaking and packaging

both the papermaking industry and the packaging industry are important components of the national economy. At the same time, the two are closely related and complementary. With the development of the national economy, this industrial chain is more obvious. The rapid development of the paper industry has effectively promoted the development of the packaging industry, and the rapid growth of the packaging industry has effectively promoted the development of the paper industry

I. diversification of paper products

as we all know, paper is one of the four great inventions in China, which was invented by Cai Lun of the Eastern Han Dynasty in 105 A.D. However, because China has been in a feudal, semi colonial and semi feudal society for a long time, the productivity is very backward, so that China's paper industry has remained in the manual workshop stage for more than 1700 years after its invention. It was not until 1891 that lunzhang paper mill was founded in Shanghai, and machine-made paper began to exist. For a long time, the main use of paper is in cultural life, such as publishing, education, office, post, etc. With the development of economy, the progress of society and the improvement of people's living standards, the output of paper is increasing and the quality is gradually improving. More importantly, the product structure has undergone fundamental changes. Paper is used more and more widely. It is not only a consumer goods, but also an important raw material; It is not only a means of living, but also a means of production; It is closely related to all departments of the national economy and has become an indispensable material in economic construction, foreign trade, people's cultural life and daily life

the varieties of paper in the world are becoming more and more diverse, from more than 400 in the 1980s to more than 600 at present. If divided by purpose, there are generally the following categories

first, cultural paper. It not only increases the demand, but also requires many varieties, good quality and high grade. In addition to the previous paper, printing paper, writing paper, glossy paper, etc., there are more and more papers that meet various printing requirements, such as single offset paper, double offset paper, coated paper, etc; Office paper, such as copy paper, carbon paper, fax paper, recording machine paper, etc. are also adding 6, nano-2 silicon oxide

second, household paper. At present, its consumption is not large, especially in rural areas. Compared with the per capita consumption of developed countries, there is a big gap, but the development potential is also great. With the improvement of people's daily living standards and the development of catering, tourism and other service industries, the consumption of household paper has not only increased significantly, but also the variety has gradually increased. In addition to toilet paper, there are napkins, face towels, wiping paper, kitchen paper, urine paper, etc

third, packaging paper and paperboard. With the development of commodity economy, especially the expansion of export commodity trade, its demand has increased rapidly, such as kraft paper, paper bag paper, white paperboard, carton board, corrugated base paper, etc. In recent years, the demand for high-quality packaging paper and packaging and decoration printing paper, such as composite packaging paper, aluminum foil paper, secondary coating paper, high gloss paperboard, etc., is increasing significantly

fourth, special paper and paperboard and other paper and paperboard, although the demand growth rate is not large, but there are many varieties. Such as liner paper, vapor phase antirust paper, three cleaning filter paper, etc. for the mechanical industry, cable paper, capacitor paper, green shell paper, electrical insulation paper, etc. for the electrical industry, acid and alkali resistant filter paper, electrolytic asbestos paper, rubber paper, etc. for the chemical industry, wall paper, linoleum paper, sound insulation paperboard, etc. for the building materials industry, spindle paper, sliver tube steel sheet paper, etc. for the textile industry; Electrical drawings for medicine, water-soluble pharmaceutical paper, etc; There are fire-resistant and flame-retardant cardboard and so on

nowadays, papermaking is one of the traditional industries related to the national economy and the people's livelihood. It is the pillar industry of light industry and has also become the pillar industry of regional economy in some provinces and cities in China. According to the survey of comprehensive information by China Paper Association, there were about 3500 paper and paperboard production enterprises in China in 2004. The production of paper and paperboard in China was 49.5 million tons, and the consumption was 53.49 million tons. Both the production and consumption ranked second in the world, second only to the United States. The production and consumption of various products of paper and paperboard are as follows:

first, the production of cultural paper is 16.2 million tons, accounting for 32.7% of the total production, and the consumption is 17.13 million tons, accounting for 31.5% of the total consumption. Among them, the production of paper is 3 million tons, accounting for 6.05% of the total production, and the consumption is 3.1 million tons, accounting for 5.7% of the total consumption; The production of uncoated printing and writing paper is 10.2 million tons, accounting for 20.6% of the total production, and the consumption is 10.45 million tons, accounting for 19.2% of the total consumption, which is still in an important strategic opportunity period of development; The production of coated paper is 3million tons, accounting for 6.05% of the total production, and the consumption is 3.58 million tons, accounting for 6.6% of the total consumption

second, the production of household paper is 3.84 million tons, accounting for 7.8% of the total production, and the consumption is 3.61 million tons, accounting for 6.7% of the total consumption

third, the production of packaging paper and paperboard is 27.8 million tons, accounting for 56.2% of the total production, and the consumption is 31.45 million tons, accounting for 57.8% of the total consumption. Among them, the production of packaging paper is 4.7 million tons, accounting for 9.5% of the total production, and the consumption is 4.96 million tons, accounting for 9.1% of the total consumption; The production of white paperboard is 6.7 million tons, accounting for 13.5% of the total production, and the consumption is 7.72 million tons, accounting for 14.2% of the total consumption; The production of carton board is 8.3 million tons, accounting for 16.8% of the total production, and the consumption is 9.56 million tons, accounting for 17.6% of the total consumption; The production of corrugated base paper is 8.1 million tons, accounting for 16.4% of the total production, and the consumption is 9.21 million tons, accounting for 16.9% of the total consumption

fourth, the production of special paper and paperboard and other paper and paperboard is 1.66 million tons, accounting for 3.3% of the total production, and the consumption is 2.2 million tons, accounting for 4.0% of the total consumption. Among them, the production of special paper and paperboard is 850000 tons, accounting for 1.7% of the total production, and the consumption is 1.14 million tons, accounting for 2.1% of the total consumption; The production of other paper and paperboard is 810000 tons, accounting for 1.6% of the total production, and the consumption is 1.06 million tons, accounting for 1.9% of the total consumption

China's per capita annual consumption of paper is only 42 kg, which is still a certain gap compared with the world's per capita annual consumption of 56 kg. However, the above data show that the consumption of paper is similar to that of developed countries, that is, the production and consumption of packaging paper and paperboard have increased rapidly, and they have ranked first among all kinds of paper, accounting for more than 55%. Therefore, it can be concluded that the paper industry is the raw material industry of the national economy. The paper industry is directly related to the packaging industry, with prominent correlation effect and great driving effect

Second, the duality of paper packaging industry

in 1980, the total output value of China's packaging industry was only 7.2 billion yuan, and the packaging industry seriously lagged behind the development of the national economy. Under the guidance of Deng Xiaoping Theory and the important thought of "Three Represents", under the correct leadership of the Party Central Committee and the State Council, under the guidance and support of governments at all levels and relevant departments, and through the joint efforts of comrades in the packaging industry across the country, China's packaging industry has been increasing at an average speed higher than the national economic development and has achieved leapfrog development. The packaging industry has developed from a bottleneck industry with missing categories, single products, low quality, decentralized management, insufficient supply, which restricts the development of the national economy, to a large industry with relatively complete categories and basically meets the needs of national economic development. According to the statistics of China Packaging Federation, the total output value of China's packaging industry in 2004 was 328.3 billion yuan, accounting for 2.4% of China's GDP in the same period. It is estimated that the total output value of China's packaging industry will exceed 350billion yuan in 2005, accounting for about 2.4% of GDP. This proportion may affect the subsequent steps in the production process, which has greatly narrowed the gap with the United States, Japan and other economically developed countries, and to a certain extent reflects the overall scale of China's packaging industry and the degree of national economic development

because packaging links all links of commodity production, storage, transportation, circulation, sales, use, etc., there are many categories of packaging industrial products, mainly including paper packaging products, plastic packaging products, glass packaging products, metal packaging products, packaging printing, packaging machinery, etc., and paper packaging products have a long history and are the traditional and most important category of packaging products. Although there are some weaknesses in paper packaging products, such as water resistance, oil resistance, poor gas resistance and low wet strength, which restrict its application scope, it has always played an important role in the packaging field. Since 1999, the output value of paper packaging products in China has exceeded that of plastic packaging products industry, jumping from the second place to the first place in the past, and the growth momentum is rapid. The output value of paper packaging products industry has accounted for more than one third of the total output value of packaging industry. In developed countries, this proportion is higher. The consumption of paper packaging products in the world's major packaging consumers, such as the United States, Japan, Germany, Australia, Sweden, Finland and so on, accounts for more than 40% or even 45% of the total packaging consumption

the reason why paper packaging products are widely used is that they have many advantages, such as light texture, easy processing and molding, good printing performance, etc. the main reason is that the world is increasingly demanding environmental protection, advocating "green packaging", and paper packaging products are harmless to the ecological environment and human health; It can be recycled and recycled; It can be incinerated or degraded, which meets the requirements of "green packaging". In recent years, there has been an upsurge of "replacing plastic with paper" in the world, causing paper packaging to further replace plastic packaging, so as to eliminate the "white pollution" caused by disposable foamed plastic tableware and plastic film bags

paper packaging products are packaging products with pulp and paperboard as the main raw materials. The product range includes paper containers such as cartons, cartons, paper bags, paper cans, paper cans, etc; Paper cushion packaging products such as pulp molding, paper liner, paper tray, paper corner protector, etc; Corrugated cardboard, honeycomb cardboard and other paper plates and their products; Paper lunch boxes, paper trays, paper cups and other disposable paper tableware. These products are widely used in the packaging of many products, such as food, medicine, chemical industry, household appliances, machinery, electronics, textiles, military industry, etc., and play a decisive role in the national economy

among paper packaging products, corrugated box is a bulk product with large output and wide range of use, whether it is used for the packaging of means of production or means of living, whether it is transportation packaging or sales packaging. Corrugated box is a necessary thing for the packaging of export goods and goods in the domestic market. It has become the most widely used packaging container in modern commerce and logistics, and it is also one of the most important packaging forms adopted by countries all over the world

in order to adapt to the trend of environmental protection in the world today, in addition to the traditional paper packaging products made of paper and paperboard as the main raw materials, pulp molding products came into being. It has the characteristics of rich raw materials, strong functionality, economy and practicality, and is a paper packaging product worthy of attention and promotion. Pulp molded products are made of reed pulp, bagasse pulp, bamboo pulp, wood pulp and wheat straw pulp, together with waterproof, oil-proof, high-temperature resistant, acid and alkali resistant, non-toxic and harmless functional additives, using different processes such as vacuum suction filtration method, vacuum injection method, plastic suction filtration method, etc. to make fast-food bowls and boxes and packaging products of industrial products, agricultural and sideline products, and military products. Its output has soared, and its varieties have also developed from a single fast-food bowl and box to commodity transportation. Its ability to reduce unnecessary noise and vibration is studied. The cushioning packaging products in transportation packaging and sales packaging have become the best products to gradually replace EPS foaming plastic tableware and cushioning packaging materials

among paper packaging products, honeycomb paperboard and its products are also outstanding, and have developed rapidly in recent years. Its honeycomb structure determines its light weight, uniform compression, high compression, bending and shear strength, and has good cushioning and vibration isolation performance; It is low cost, easy to recycle, renewable, and is
