Analysis of the situation of China's plastic packaging materials industry (Part 1)

I. overview of the plastic packaging materials industry

after more than 20 years of development, China's plastic packaging materials have formed a certain scale, occupy an important position in the packaging market, and play a positive role in the construction of the national economy. In 1980, the output was only 191000 tons and the output value was 3 billion yuan; In 2002, the output reached 4.01 million tons and the output value reached 68billion yuan, accounting for 27% of the 250billion yuan output value of the packaging industry. The level of industrial equipment has been continuously improved, and some have reached the advanced level of developed countries. A number of new products, new technologies and new materials have emerged. The market demand has increased rapidly, widely used and developed rapidly. The average annual growth rate is 12%, and in 2002, it increased by 14.2% compared with 2001. The composite packaging base material has overcome the situation of long-term import of biaxial tensile film. Now the annual export of film is about 300000 tons, and the foreign exchange earnings are $3billion. There are more than 8000 enterprises above the township level in plastic packaging materials, including 2240 in film manufacturing, 4300 in wire and rope woven products, 500 in foamed plastics, and 679 in packaging boxes and containers

the road of rapid development in the past 23 years is the road of reform and opening up, the road of socialist market economy, the road of hard work and hard work of employees in the whole industry, especially the rise of private enterprises. Jiangyin Shenda group and Zhejiang dadongnan plastic group, which made their fortune from several thousand yuan to more than 1billion yuan, are leading enterprises that have grown up in the market economy through difficulties and twists, and have become well-known large-scale packaging private enterprises at home and abroad, A number of private entrepreneurs have emerged. The original small and medium-sized plastic packaging enterprises have also gained vitality through structural adjustment, asset restructuring and technological transformation. Foshan Oriental packaging materials company and Foshan DuPont Hongji packaging materials company play an important role in the industry with a new look. In addition, the entry of foreign-funded enterprises has increased industry competitors, making domestic enterprises further feel the role of the survival of the fittest competition mechanism. Therefore, only by increasing strength, improving quality and creating famous brands can we win the initiative in the competition

Second, the economic operation of the plastic packaging industry was good in 2003

last year, the plastic packaging industry got rid of the impact of SARS and continued to maintain a steady growth trend

according to relevant statistics, it is estimated that last year, plastic raw materials increased by 16%, plastic products increased by 15.8%, and the export delivery value increased by 2. Changxing Materials Industry Co., Ltd. is an enterprise headquartered in Kaohsiung. The output of plastic packaging materials is expected to reach 460 tons, an increase of 15% over 4.01 million tons in 2002, of which biaxial tensile film, soft plastic composite packaging materials and packaging containers (bottles, boxes, barrels) increased significantly. The actual monthly output and annual forecast of main products are as follows: January to August (10000 tons)

the actual output of main products in 2003 and the annual forecast

months (10000 tons) The annual growth rate is expected to be%

150.52018

flexible packaging, of which BOPP 406020

BOPET 81220

woven products 89.51314

packaging containers 50.57016.5

foam packaging materials 20.23016

packaging sheets 18.33016

total 32946016

from the above table, the growth of biaxially stretched films is the fastest, on the one hand, because of BOPP special materials.Six domestic enterprises have produced, Accounting for 50% of the total demand, (including Shanghai Petrochemical, Beijing Yanhua, Qilu Petrochemical, Maoming Petrochemical, Guangzhou petrochemical, Jiujiang Petrochemical) meet the requirements of film drawing speed m/min, reduce dependence on foreign countries, shorten transportation time, and strive for the initiative. On the other hand, the newly increased production capacity of the introduced production line is more than 100000 tons. For example, the 25000 ton five layer BOPP film production line built by Sichuan Zhongda company in Chengdu Development Zone was officially put into operation in October, the 36000 ton BOPET production line built by Jiangsu Shuangliang group in Dujiangyan was put into production, the five layer co extruded BOPP film of Changzhou Wujin Jinshi Group was put into operation in August, and the 20000 ton BOPP production line of Fushun Petrochemical Company was put into operation in May, Fujian modern plastics company and Anhui Tongfeng company have also introduced BOPP production lines with an annual output of 25000 tons and 30000 tons respectively, which are also under construction. Among them, the high-performance molecular assembled antibacterial film produced by Guangdong Shunde Deguan company and Guilin Jiqi packaging company will be put into the market, which makes the two enterprises take a gratifying step in innovation. In short, innovation has become the driving force for the development of plastic packaging. The laser anti-counterfeiting film of Shanghai Zijiang color printing company, the breathable cast film of Zihua company, and the anti electrostatic current cast polypropylene film of Wisteria company are all listed in the national torch project. Nanjing Zhongda coextrusion heat sealing biaxial tensile polypropylene film maintains the heat shrinkage of BOPP, solves the problems of heat sealing and cigarette film packaging, solves the problem of adhesion between medium film and small film, and solves the problem of heat sealing of BOPP by using opening positioning technology

the rapid development of plastic packaging is inseparable from the market development of related industries. The growth rate of food and soft drink packaging market is more than 20%. Therefore, the transparent polypropylene market has been rapidly expanded; The implementation of green food engineering in the processing of agricultural and sideline products provides new opportunities for the plastic packaging market. Taking the launch of Liaoning green food industry chain as an example, it involves 100 production bases in 100 counties in 9 provinces and cities, including Liaoning, Dalian, Jilin, Heilongjiang, Inner Mongolia, Shandong, Hebei, Hainan, etc., including the packaging of more than 3000 varieties of grain and oil, fresh vegetables, dried and fresh fruits, fresh milk and dairy products, condiments, raw and fresh meat, poultry eggs, etc. it is a challenge to packaging from all aspects of production, processing, packaging, transportation, storage, and sales, All these have promoted the expansion of plastic packaging materials market

III. current development trend and characteristics of plastic packaging

(I) development prospect of plastic packaging materials in the world

internationally, although plastic packaging materials have been facing serious challenges from environmental problems, according to the data published in recent years, plastic packaging is still one of the materials with the fastest demand growth in the packaging industry. According to the statistical analysis and prediction of American Freedonia group, the average growth rate of paper and plastic in the packaging field in the United States from 1996 to 2001 was 2.4%, including 1.6% for paperboard and 3.4% for plastic. According to the statistical data of Japan's "packaging technology", the sales volume of plastic packaging materials in Japan accounts for 15.4% of the total sales volume of all kinds of packaging, still ranking second after paper and paperboard (57.5%), the rest are metal 12%, glass 9.2%, wood 5.2%, and others 0.7%

according to the above development and prediction of the United States, Japan and China, it is obvious that plastic packaging materials will continue to grow steadily in the 21st century, remain vibrant in the field of packaging materials, and continue to play an active role in protecting commodities and improving the value of commodities

The 21st century is a century of environmental protection. Environmental problems are becoming more and more important, and resources and energy are becoming more and more tense. Plastic packaging materials will usher in new opportunities and face severe challenges. In order to meet the requirements of the new era, plastic packaging materials are not only required to meet the increasing requirements of market packaging quality and efficiency, but also further required to save energy and resources, The starting point of technology development is that it is easy to be recycled or degraded by the environment after use. Therefore, plastic packaging materials are developing in the direction of high function, multi-function, environmental adaptability, the use of new raw materials, new processes, new equipment and the expansion of application fields

high functional and multifunctional plastic packaging materials have become the hot development packaging materials in many countries, and some products have been put into industrial production. Such materials include plastic packaging materials with high impermeability, multi-functional freshness, selective permeability, heat resistance, sterility (anti-bacterial), rust prevention, deodorization, shape memory, resealability, easy unsealing, etc. among them, high impermeability, multi-functional freshness preservation, sterile packaging materials, etc. are developing more rapidly, and will become the focus of development at the beginning of the 21st century. In addition, nanocomposite packaging materials under research and development in recent years will receive greater attention

at the beginning of the 21st century, with the increasing growth of the world economy and the continuous development of high technology, products are changing with each passing day, and people's lives are more convenient and leisure. Both daily necessities packaging, food packaging and industrial packaging have higher requirements. On the other hand, with the growing call for environmental protection, on the premise of meeting the packaging function, we should try to reduce the amount of garbage, so as to show that packaging films, containers and sheets are becoming lightweight The key technology of thin-walled development trend is to actively adopt new raw materials with super toughness, which can process thinner and easier to process, such as bimodal polymer HDPE, metallocene catalyzed polyethylene, polypropylene and polystyrene plastic alloys, which provide more raw material choices for plastic packaging. In particular, the development of polyethylene and polypropylene has further improved many properties of the flexible packaging structure, such as toughness, transparency, impermeability, heat resistance and puncture resistance, and can reduce the heat sealing temperature, improve processability, and improve the speed of the packaging production line. One of the characteristics of polyethylene food packaging film is that it can control the permeability of oxygen, carbon dioxide ratio and water vapor, and can be used for controlled atmosphere packaging. It can greatly extend the shelf life of food, mainly used for semi-finished product packaging such as supermarket salad, carrot slices, cauliflower and meat, as well as fresh-keeping bags of agricultural products, impermeable shrink packaging bags, etc. it is expected that by 2000 in the United States, the shelf capacity of such semi-finished products will increase from 3% in the mid-1990s to 25%, The sale of agricultural products in the form of fresh picking will reach 25%, and the demand for MPE controllable modified atmosphere packaging film will increase greatly

on the basis of the development of the 20th century, plastic blends, plastic alloys and inorganic materials filled and reinforced composites (ABC), which are known as the stars of tomorrow's plastics, will further improve and perfect the production and processing technology, and make greater progress in product performance improvement, serialization and functionalization through the joint efforts of basic research, which will improve the quality of plastic packaging, Under the specified conditions, the added value and environmental protection will have a greater impact on the network control of the extrusion molding production line and the development of new products.

the data shows that with the improvement of the quality of plastic packaging products, the increase of functionality and the continuous development of new varieties, their uses have also been further expanded, especially the high resistance plastic packaging materials, which are mainly food packaging, have gradually expanded the field of non food packaging, including industrial packaging Pharmaceutical packaging, agricultural and sideline products packaging, building materials packaging, marine supplies packaging, etc. will be further developed

entering the 21st century, the deepening of the major adjustment of the world economy and the transformation of sustainable development strategy are the general background of the world's industrial reform, as well as the background of the environmental change of the plastic industry. Compared with traditional packaging materials, plastic packaging materials can save energy, save resources, reduce waste production and reduce environmental load from the analysis of the whole product life cycle evaluation, Therefore, development still occupies an important position and plays an important role in the early 21st century, but a considerable part of plastic packaging materials are disposable consumer goods, which are difficult to degrade in the natural environment after use, and can not be ignored
