Development situation and trend of packaging paper

  • Detail

With the further increase of the output of the paper packaging industry and the continuous use of equipment and devices in developing countries, the world paper industry in 2003 was significantly better than that in 2002, and the amount of packaging paper increased significantly

with the rapid growth of demand, the world's paper and paperboard operating rate has increased significantly. The world's paper and paperboard output in 2003 increased by 11million tons compared with that in 2002. Chinese manufacturers continue to increase investment, which will drive the world economic growth

from the perspective of countries, in recent years, with the rapid development of packaging and printing technology, the packaging paper industry in the United States has shown a good trend of continuous growth. Advanced technology has been more widely used, productivity has further improved, and turnover has also continued to increase, especially the growth rate of folding cartons, flexible packaging and label printing has significantly exceeded that of other processing departments

an American enterprise developed paper that can convert solar energy into heat energy, which acts as a solar collector. This paper is used to package food and put it in the place where the sun shines. In addition, it is the AD converter. If the number of bits of the AD converter is low, that is, the resolution, the food in the package will be heated. Only when the package is opened, the heat will dissipate

the packaging paper industry in South Korea has developed rapidly in recent years, and the production of paper industry has been growing. According to the data of the Korea Paper Industry Association, the domestic consumption of packaging paper in South Korea in 2002 was 7.348 million tons, an increase of 4.2% over 2001; The export volume was 2.378 million tons, accounting for 25% of the total production; In 2003, the output of packaging paper in South Korea exceeded 10million tons, setting a record

in Russia, packaging paper with lighter weight and better strength is widely used. In 2002, the consumption of kraft wrapping paper in Russia was 316000 tons. It is expected that by 2007, its consumption will reach 390000 tons, an increase of nearly 30% over 2002. On the one hand, the growth of kraft packaging paper is due to the increased demand for a large number of high-quality building materials, which drives the consumption of high-quality Kraft packaging paper; On the other hand, the continuous improvement of product quality has promoted the export volume of Russian Kraft packaging paper

in October 2003, Vietnam drew up an investment plan to strengthen the production of packaging paper products, with a budget investment of US $4.339 billion. The plan clearly planned the output of various paper materials. To prove this, 1.26 million tons of paper products can be produced every year by 2010, including 126000 tons of newspaper printing paper, 632000 tons of packaging paper, 324000 tons of printing paper and writing paper, and 179000 tons of other paper products, an increase of 9.2 times compared with 2000. At present, the annual pulp output of Vietnam's paper industry is only 455000 tons. 98% of domestic enterprises are small and medium-sized enterprises, with outdated equipment, backward technology and high costs. Vietnam's paper industry is taking a series of measures to change this situation

from the perspective of paper products, the world market demand for packaging paperboard will increase at a rate of 2.8% per year. It is expected that by 2010, the market demand will reach 125 million tons, and the production will be relatively concentrated. Eastern Europe, the Middle East, Asia and Latin America are the regions with the fastest growing demand for packaging cardboard in the world

at present, Oceania is the most concentrated area of packaging board production, followed by Africa and Japan. In the next few years, the concentration of packaging board production will continue to develop. In the global packaging board production, North America accounts for 39%, Western Europe 21%, Asia 28%, Latin America 6%, Eastern Europe 3%, and the rest is Africa and Oceania. In terms of production facilities, Nordic and Oceanian countries have the most modern large paperboard machines, while eastern European, Latin American and African countries retain small old-fashioned equipment

it is expected that North America and Western Europe will maintain the leading position in the production of packaging paperboard in the future. The output before 2010 will still account for 45% of the global total output, and continue to become a molding processing region with good industrial exports of packaging paperboard in the world

in recent years, the demand for paper packaging has declined due to the squeeze of plastic packaging in the European and American packaging market. According to statistics, the demand for carton base paper and folding carton in the United States in 2002 decreased by 6.3% and 2.6% respectively compared with 2001, while the current growth rate of the packaging industry is only 1.5% - 2%, and the slowdown in the growth rate is precisely due to the reduction in the use of paper packaging materials

in the past four years, the American corrugated packaging Federation has spent $2.3 million annually on the promotion and standardization of cartons and cartons, but this situation has not been improved. In Europe, the prospect of paper packaging is not optimistic. At present, retailers are increasingly enthusiastic about using reusable plastic boxes

according to a survey of the food retail industry in the European market, the use of plastic boxes in Britain, France and Germany is about 30million tons, 16million tons and 40million tons respectively

it is estimated that 21million tons of corrugated packaging market share will be replaced by plastic boxes in 2005, with a replacement rate of five times that of 2002. German enterprises have put forward three new requirements for the corrugated boxes used in China's food exports. These requirements are: there should be no wax paper or oil separator in the boxes; Try to seal the box with glue instead of plastic tape; There should be no metal nails outside the carton, but glue all sides

fruit and vegetable paper Takasaki paper company of Japan produces fruit pulp paper from apple pomace discarded in the food industry. The method is very simple. Remove the particles in the fruit pomace, pound it into pulp, and add an appropriate amount of wood fiber. This kind of fruit residue paper is easy to decompose after use, can be burned or composted, and can also be recycled for papermaking, which is not easy to pollute the environment

a Japanese Research Institute used new technology to make a kind of edible wrapping paper with certain nutritional value that melts in the presence of heat, using soybean dregs as raw materials. It is especially suitable for the packaging of fast-food noodles seasoning, and can be eaten together with the packaging

the carrot paper developed in the UK is based on carrots, added with appropriate thickeners, plasticizers and water repellents, and made of the natural color of carrots to make edible colored vegetable paper with good quality and low price. This product can be used in the individual packaging of boxed food or directly used as convenient food, which can not only reduce environmental pollution, but also enhance the beauty of food and increase consumers' interest and appetite. Carrot paper is a kind of edible colored paper, which has strong flexibility and certain water resistance, and has packaging and edible functions. If we can further improve the strength and plasticity, improve the surface texture, and make products of various shapes, we can further expand its use, better protect the environment, and provide a new way to test its breaking strength for the deep processing of vegetables

foam paper a German company has developed a new process for the production of foam paper. The packaging materials produced by it can replace foamed plastics. This kind of foam paper uses old book scrap paper and flour as raw materials. First, the recycled old books and newspapers are cut into pieces, and then ground into fibrous pulp. It is mixed with flour in the ratio of 2:1. The mixed paper pulp is injected into the extruder and pressed into cylindrical particles. In the extrusion process, the raw material becomes foam shape under the action of water vapor. With this kind of foam paper particles, various shapes of packages can be produced according to different needs. Foam paper can be formed at one time without chemical additives, and can be recycled and processed after use
