The development status of China's metal packaging market and foreign technological innovation

I. the market pattern of China's metal packaging

metal packaging is an important part of China's packaging industry, and its output value accounts for about 10% of China's packaging industry, mainly providing packaging services for food, cans, beverages, fats, chemicals, pharmaceuticals, cosmetics and other industries. Metal packaging container refers to the thin-walled packaging made of metal sheet, which is widely used in food packaging, pharmaceutical packaging, instrument packaging, industrial packaging, ammunition packaging and other aspects, of which the largest number is used for food packaging. The largest user of metal packaging in China is the food industry, followed by chemical products. In addition, cosmetics and drugs also account for a certain proportion

in metal packaging, tinplate packaging is the main. Due to the continuous improvement and perfection of sheet printing technology and processing technology, sheet packaging is more and more widely used. With the improvement of the production capacity of domestic tinplate, the import of tinplate will be gradually reduced, and it will soon be self-sufficient, but some high-end products still need to be imported in a small amount

the recovery of the international market: Plastic Extruders regain confidence. The reason why metal packaging containers are widely used in graphene flexible transparent keyboards displayed at the meeting is that they have many unique advantages: compared with other packaging containers, such as plastic, glass, paper containers, etc., metal containers have high strength, good rigidity, and are not easy to crack. Compared with any other material, metal sheet has excellent barrier, gas barrier, moisture resistance, shading, fragrance retention, and reliable sealing, which can better protect products. Metal materials have good printing performance, bright and beautiful patterns and trademarks, and the packaging containers made are eye-catching, which is an excellent sales packaging. Metal containers can be made into various shapes according to different needs, such as round, oval, square, horseshoe, trapezoid, etc., which not only meets the packaging needs of different products, but also makes the packaging containers more changeable and promotes sales

metal packaging products can be divided into iron printing products (cans, boxes), cans (including aluminum two-piece, steel two-piece, tinplate three piece cans), aerosol cans (tinplate made of exquisite pharmaceutical cans, pesticide cans, cosmetics cans, etc.), food cans (cans, liquid or solid food cans, etc.) and various bottle caps (crown caps, unscrew caps, aluminum anti-theft caps). In addition, there are chemical barrels made of L tinplate and steel barrels made of L cold rolled sheet and zinc sheet

the equipment of China's metal container manufacturing industry has strong strength. There are 26 pieces of cans with an annual production capacity of more than 11 billion (the current market demand is about 7 billion). Tinplate three piece can manufacturing equipment has more than 500 imported and domestic full-automatic or semi-automatic production lines of various models, and its products supply about 4billion to the beverage industry and about 3.8 billion to the food canning industry every year. The annual production capacity of aerosol cans reaches 600million. The annual processing capacity of steel barrels is about 40million-50million. Iron printing equipment has more than 500 production lines across the country, with half imported equipment and half domestic equipment, printing more than 16 billion times a year

at present, China's metal packaging market shows a trend of supply exceeding demand, but from the analysis of per capita consumption, there is still much room for development. China's annual consumption of beverage cans is 11billion cans (7billion two-piece cans and 4billion three-piece cans), and the per capita consumption is less than 8 cans, while Japan's annual consumption is 18billion cans and South Korea's is 3.2 billion cans. If China's annual per capita consumption increases to 10 cans, it will require a supply capacity of 13billion cans per year; In addition, the consumption level of canned food in China is low, with an average annual consumption of less than 1.5kg per capita. The average annual consumption level of canned food in Europe is 50kg, and that in Japan is 23kg

II. Technological innovation of foreign metal packaging

1. Coated steel plate

from the current development trend, coated steel plate has been used as packaging materials, and shows a rapid development trend. Coated steel plate, namely organic coated steel plate, refers to the coated metal material obtained by applying organic paint on the surface of steel plate. Such coated steel plates do not need to be painted after making various packaged products in the packaging industry, so they are often classified as pre coated steel plates. According to the estimation of relevant experts, coated steel plates will be widely used in the metal packaging industry to replace the backward production process of coating metal packaging products in the production process

coated steel plates are generally produced centrally by metallurgical enterprises, which greatly reduces the cost of packaging manufacturing due to the omission of the coating process in the production of products. It is estimated that the cost of packaging products with thin steel sheet as raw material can be reduced by 5%-10%, saving energy by 1//5, especially saving a lot of investment in the pretreatment of packaging products and coating equipment. Coated steel plate has the advantages of both organic polymer and steel plate. It has not only the good coloring, formability and corrosion resistance of organic polymer, but also the high strength and machinability of steel plate. It can be easily processed such as punching, bending, deep drawing and welding

at present, there are about 474 coated steel plate production lines in nearly 200 companies in 40 countries and regions around the world. There are about 200 production lines in the United States, more than 50 in Japan, 120 in European countries and 74 in Asia. At present, the annual production capacity of coated steel plates in the world is 14million tons, including about 4.5 million tons in the United States, about 4million tons in Europe, and about 270 tons in Japan (1). Industry: as the largest consumption field of vanadium utilization, million tons, and about 1.2 million tons in other countries in Asia. The total annual production capacity of the United States, Japan and Europe accounts for about 84% of the total production capacity of the people's office. According to incomplete statistics, as of May, 2004, China has built 24 coated steel plate production lines, forming an annual production capacity of 1.616 million tons. In addition, there are more than ten production lines under construction and preparation

2. Automatic cooling and heating beverage cans

the self cooling cans developed by American self cooling cans Co., Ltd. (ccnv) are very convenient to use. As long as you press the plastic button at the bottom of the beverage cans, the temperature of the beverage cans can be reduced within minutes. Self cooling cans mainly use a patented technology of heat exchange system (HEU) to achieve the function of automatic cooling of beverage cans. HEU includes many components, such as beverage cans, built-in HEU containers, activated carbon, CO2 gas, etc. The working principle of HEU is very complex. HEU should keep the activated carbon adsorbing CO2 stable, and when the internal pressure of HEU drops, CO2 can be effectively released and achieve the function of heat absorption

a self heating sake can appeared in Japan. There is an interlayer at the bottom 1/5 of the tank, which contains quicklime and a small packet of water in the sealed plastic film. Before drinking, just use an attached plastic stick to insert it into the hole at the bottom, and the water will immediately mix with quicklime, generating a lot of heat. It only takes 3 minutes to heat a can of sake to 58 ℃

Nestle UK recently launched a 330ml new concept of automatic heating milk coffee cans. The principle is to place water and quicklime in the interlayer of the tank respectively and generate heat through chemical reaction. Therefore, the volume of the tank is reduced, which can hold 210ml of liquid beverage. For the convenience of consumers, a round pull ring is designed on the top of the jar. The heating process is controlled by the button at the bottom. About 3min, the beverage can reach 60 ℃. In order to prevent consumers from being scalded by hot drinks, the outer layer of the can has a corrugated isolation layer and a specially designed shrink sleeve

III. problems existing in China's metal packaging industry

1 Lack of high-end products

at present, in the market, the production capacity of two-piece cans, three piece beverage cans, crown caps, and chemical barrels below 18L is excessive, and the capacity of high-quality and high-end products is obviously insufficient. There are too few enterprises that can produce small capacity, ultra-thin cans, special-shaped cans suitable for supermarket shelf effects, and high-quality cans. The variety of cans is single, which is difficult to meet the requirements of further development of packaging, and restricts the development of metal packaging

2. The industrial concentration is low

the metal packaging industry is also an industry dominated by small and medium-sized enterprises and private enterprises. Common phenomena exist, such as small scale, low degree of intensification, low-level repeated construction, assimilation of quality structure, price competition, etc. There are about 60 domestic enterprises with an annual consumption of more than 10000 tons of tinplate, and COFCO Meite (including Wuxi Huapeng bottle cap and Guangzhou Panyu Meite), a domestic leading enterprise, consumes 7. 5% of tinplate annually 50000 tons, production and sales of 800million yuan. In addition to COFCO Meite, there are also large-scale enterprises such as Beijing org Xinmei group, Fujian Shengxing group, Fujian Jiamei group, Sanshui Jianlibao can making company, Haikou coconut can making company, Shanghai Meilin can making group, which still lags far behind the large-scale enterprises in developed countries

3. Excessive dependence on imports

most of the equipment in the metal container industry is imported. At present, the international mainstream equipment has developed in the direction of digitalization, networking, high-speed and low consumption, more environmental protection and humanization, while China's dependence on imports of major metal packaging equipment and materials has not been fundamentally changed. It is suggested that the competent machinery manufacturing department should pay attention to improving the performance of packaging machinery and equipment and strive for less imports, which is conducive to saving foreign exchange. Except for iron printing equipment and aerosol tank equipment, the introduction of other equipment should be cautious to avoid repeated introduction

according to a survey of the metal Commission, the annual demand of the aluminum can market has hovered around 7billion in recent years, and the annual demand of the cold rolled steel barrel Market is about 60million. Metal cans are made of tinplate cold pressed plates and aluminum plates, which belong to high-tech packaging materials. In 2004, the metal container industry purchased 1.5 million tons of tinplate, a considerable part of which came from imported plates; In addition, importing raw boards from abroad and processing tin plating at home have made the country pay a lot of foreign exchange. Due to the great dependence on plates, when China's steel industry raised the flag of anti-dumping in 2003 and 2004, the sales price of tinplate rose all the way, and the industry encountered unprecedented difficulties (the price has been increased by more than 80% since June 2002, while the increased cost of the metal can industry was transferred to the downstream industry by less than 20%)

4. Serious waste of resources

as the current economic growth mode of China's packaging industry is still extensive, the consumption of resources is large, which is twice the world average level and 4. 5% of the United States 3 times, Japan's 11 5 times. China's energy consumption per unit of GDP is four times that of the United States and seven times that of Japan. For metal packaging, the power consumption of iron aluminum packaging materials (containers of the same volume) iron is 0 7kw/h, 3kw/h for aluminum, and the energy consumption ratio is much greater than that of other packaging materials

at present, the country has not formed a complete set of effective mechanisms and relevant policies for recycling packaging waste, so the recycling rate of waste is low and the waste of resources is serious

IV. promote the development of China's metal packaging industry

1 At present, the key to the development of metal packaging enterprises is how to get out of the shadow of low-level, homogeneous and price competition and transition to the competition of difference, scale, internationalization and high value-added products. Many large domestic enterprises have made successful explorations. COFCO Hangzhou Meiwu, org can making, Fujian Shengxing, Shanghai Meilin can making, etc. follow the group and large-scale development mode: Taking COFCO Hangzhou as an example, from a single regional brand company in Hangzhou, it rapidly expanded to three points in South China, East China and North China within one year, radiating the pattern of the national ball screw as the E5 market, and becoming the development and production base of iron printing packaging containers of China Packaging Federation. With Beijing as the leader, org can manufacturing Co., Ltd. now has a number of joint ventures or joint ventures in Hainan, Beijing, Shandong, Xinjiang and other branches, which is also a model of integration. And Dongguan Tianbao hardware products factory
