Current situation and development trend of plastic packaging materials

I. overview of plastic packaging materials industry

after more than 20 years of development, plastic packaging materials in China 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

comparison with relevant data in 1980. In 1980, the output was only 191000 tons, with an output value of 3 billion yuan. In 2003, the output reached 4.65 million tons, with an output value of 70billion yuan, accounting for 26% of the 270billion yuan output value of the packaging industry; The equipment level of the industry has been continuously improved, and some have reached the advanced level of developed countries, and a number of new products, new technologies and new materials have emerged; The market demand is growing rapidly, widely used and developing rapidly, with an average annual growth rate of 12%, which was 16% higher in 2003 than in 2002; 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

the number of Enterprises above designated size has developed rapidly. There are more than 8000 plastic packaging material enterprises above Designated Size, including 2240 in film manufacturing, 4300 in wire and rope woven products, 500 in foamed plastics, and 679 in packaging boxes and containers. According to the figures of the recent industrial census, there are 546 plastic enterprises in Dongguang County, Hebei Province alone, with a production capacity of 100000 tons

a number of industry leading enterprises have emerged. Jiangyin Shenda group and Zhejiang dadongnan plastic group, which grew up from several thousand yuan to more than 1billion yuan, have become well-known large-scale packaging private enterprises at home and abroad after fighting in the market economy; 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

II. The economic operation of the plastic packaging industry was good in 2003

1 Large scale and technological innovation promote the development of soft plastic films

(1) soft plastic films show a large-scale development trend. Biaxially stretched film has the fastest growth. On the one hand, BOPP special materials have been produced by six domestic enterprises, accounting for 50% of the total demand (including Shanghai Petrochemical, Beijing Yanhua, Qilu Petrochemical, Maoming Petrochemical, Guangzhou Petrochemical and Jiujiang Petrochemical), reaching the requirements of film drawing speed of 350 ~ 400m/min, reducing dependence on foreign countries; On the other hand, the introduced production line was put into operation in 2003, with a new added capacity of more than 100000 tons

(2) combining capital with regional advantages. Mao Fang lead and Wu Changshuo, investors in Wenzhou, took a fancy to the northern market, established Deli company in Ling County, Shandong Province, and introduced a BOPP production line with an annual output of 15000 tons. It was introduced in 2001. In 2003, the output value reached 220 million yuan and the annual tax reached 60million yuan

(3) innovation has become the driving force for the development of plastic packaging. 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 has taken a gratifying step in innovation; 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. In short, innovation has become the driving force for the development of plastic packaging

2. Plastic knitting industry has overcome various difficulties and achieved gratifying results

(1) plastic knitting and blow molding, compounding, color printing, plate making and other supporting processes have developed synchronously, which has improved its competitiveness in the international market, increased its export volume, and effectively occupied the Asian American market

(2) the rapid development of plastic knitting machinery has promoted the development of woven products. Since 2003, the technical level of plastic wire drawing machines, circular looms and supporting equipment has improved to varying degrees, and a number of new products have emerged. A new type of film coated cylinder plastic woven bag combined unit has come out. The unit integrates six processes: compounding, automatic waste edge cutting, automatic punching, front and back multicolor printing, shifting and folding, and seven character cutting technology, saving labor and materials, reducing costs, and improving quality. On the other hand, more weaving machinery enterprises have increased their exports to the international market, from the past to the Philippines, Peru, Jordan and other developing countries, and then to South Korea, Brazil and European and American countries. The prospect is promising. Zhejiang Yanfeng Plastic Machinery General Factory exports small four shuttle circular looms in batches, which is expected to reach US $2million this year. The small six shuttle circular loom of Wenzhou Hengyi plastic machinery company has been adopted by American plastic knitting enterprises

(3) asset restructuring makes the enterprise grow and develop continuously. It is a farsighted practice for Mr. Ye Qile, a Wenzhou plastic knitting enterprise, to seek development in Sichuan and occupy the plastic bag packaging market required by the feed group. In 1995, he established Jinlu packaging company in Xinjin County; In 1998, Xinle plastic company was jointly established with Sichuan hope agricultural company; In 2000, Qile plastic knitting group was established; In 2002, with an investment of 100 million yuan, the enterprise has 600 plastic knitting machines, with an output value of 300 million yuan; This year, Zhejiang longxinglong Industrial Co., Ltd. and more than 40 local plastic knitting enterprises formed a plastic knitting enterprise group. It is expected that the output value will reach 800million yuan within two to three years after production, and will become the largest plastic knitting group in the industry

3. The output of plastic packaging containers (barrels, bottles, boxes) increased rapidly

the annual output of plastic packaging containers (barrels, bottles, boxes) reached 730000 tons, among more than 600 enterprises, 24 were more than 5000 tons, 4 were more than 10000 tons, Zijiang group 95800 tons, accounting for 15%, ranking first in the country, Hebei Xingtai Jin county 29400 tons, accounting for 3.2%, Zhongfu 13500, followed by Sanshui Jianlibao, Dongguan Yihuang, etc

III. current development trend and characteristics of plastic packaging

1 The production of domestic BOPET film was more than 140000 tons in 2003. Its consumption structure was that packaging materials (composite printing film, Tangjin film, vacuum aluminum plating film) accounted for 57%, insulation and electrical special films accounted for 15%, photosensitive materials accounted for 13%, audio and video accounted for 5%, card protection film accounted for 6%, graphics and decorative film accounted for 4%

The development of CPP is also very rapid. At present, more than 60 sets of CPP production lines have been introduced in the whole industry, with a total production capacity of more than 150000 tons

at present, CPP film is mainly used for composite packaging in the domestic market. Take 2002 as an example, accounting for 64% of the total output (about 64000 tons); Aluminum coating accounts for 21% (about 21000 tons); Cooking film accounts for 15% (about 15000 tons), and a batch of cutting-edge new materials are distributed in advance; That is, by configuring appropriate accumulators in the hydraulic system, the high resistance diaphragm and cooking bag membrane have some imports. The advanced five layer coextrusion cast film can produce high-grade CPP. The product market is positioned as high barrier film and high-temperature cooking film. It has a promising prospect in the domestic market, but it also faces the fierce competition of multi-layer coextrusion blown film. The multi-layer coextrusion high barrier film (PET or PA) has been used in the packaging of liquid food, milk, ham sausage, fresh meat packaging, oil resistant food, large infusion and other aspects, and its consumption has increased. The competition with CPP five layer coextrusion cast film deserves attention. This is also the main reason why some CPP production enterprises have reduced sales in recent two years, failed to give full play to their production capacity, and reduced prices

2. High barrier and multifunctional film is developing to a new technical level

high barrier and multifunctional soft plastic packaging materials have become a hot spot in recent years. The original composite film is developing to a deeper level, and the bag making and printing technology has reached a new level, entering the era of "Color Revolution". There are offset, gravure and flexographic color systems in the whole industry, which promotes the in-depth development of flexible plastic packaging materials. Anti counterfeiting packaging film is developing with each passing day, which is called the flower of soft plastic packaging. In particular, the successful development of anti-static packaging film is of great significance

3. The development of multi-layer coextrusion technology has changed the product structure of functional films and containers, and adapted to the market demand

coextrusion packaging film process equipment has the advantages of low investment, low cost, strong adaptability and convenient operation. Relevant data show that coextrusion packaging film accounts for 40% of the whole flexible plastic packaging materials in developed countries, while we only account for 6%, and dry composite film is still the main method. At present, our co extrusion technology has also made new progress. The stacking head technology of Dalian Liaonan Dongfang Machinery Co., Ltd. has been popularized and applied, and the domestic coextrusion blow molding technology and equipment have passed the product identification and began mass production. The five layer co extrusion high barrier film blowing unit developed by Guangdong Jinming plastic equipment company has passed the new product appraisal. The development of CO extrusion packaging film will change the product structure of multifunctional film, which is suitable for the packaging of liquid food, milk, fresh meat and other food

The development of coextrusion technology also meets the needs of industrial packaging. Qinchuan machinery company has successfully developed a six layer coextruded plastic hollow container for the production of automotive fuel tanks, with a maximum volume of 200 liters. The production of this machine has changed the single-layer situation of automobile fuel tank. With the development of automobile industry, the market of multi-layer fuel tank will have greater development space

4. The market prospect of fresh-keeping packaging film for vegetables and fruits is broad.

the total output of fruits and vegetables in China reached 71 million tons in 2000, and the output of vegetables was 300 million tons. China is the world's largest fruit and vegetable production and sales country. However, about 30% of the fruits are lost in the process of storage, transportation and sales. Among them, improper packaging is one of the causes of fruit decay and loss. How to inhibit the metabolic process of fresh fruits and vegetables after picking, reduce the consumption of nutrients, and maintain their flavor quality is an important topic of fresh-keeping packaging. At present, polyethylene film and polypropylene film are the most widely used packaging materials for fresh fruits and vegetables

5. Attractive business opportunities lurk in the plastic beverage bottle Market

the introduction of a large number of injection, drawing and blowing technology and equipment has promoted the development of PET bottles. In just a few years, PET bottles have become the mainstream packaging materials for edible oil and beverage bottles. At the same time, the demand for PET bottles in cosmetics, medicine and other industries is also increasing. In 1996, the output of PET bottles was 3billion, increased to 5billion in 1998, reached 8billion in 2000, 9billion in 2001 and 10billion in 2002. With an annual growth rate of 18%, it has become the largest variety of plastic packaging materials

according to the survey, China's beverage output is about 22million tons, increasing at a rate of more than 20% every year. The application proportion of PET bottles in carbonated beverage packaging accounts for 57.4%, and the market prospect is promising. At present, the enterprises with large PET bottle output in the industry include Zhuhai Zhongfu and Shanghai Zijiang group, which respectively occupy 30% and 20% of the domestic PET bottle market share; The domestic tea beverage market has sprung up, with an output of 3million tons. Therefore, hot filled 85 ~ 90 ℃ PET bottles have become the fastest-growing variety of polyester bottles, with an annual growth rate of more than 50%

The development of transparent polypropylene packaging bottles is a hot spot in plastic packaging at home and abroad in recent years. High transparent PP can be widely used in injection, blow extrusion, blow drawing, extrusion, hot containers, food, medicine bottles, etc. its price is appropriate. It is a competitor of PS, ABS, pet, PE bottles, and has a broad market prospect

6. The application of beer plastic packaging bottles has been spring in the branches

(1) the development of heat-resistant polyester bottles (PET) used internationally in the beer packaging industry in recent years is rapid, especially the application of PET bottle coating technology (plasma technology), which is coated with 0.21mm carbon layer inside. Its permeability is almost the same as that of glass, and it can withstand high-temperature sterilization
