Problems and development prospects of metal packaging

after considerable development, the metal packaging industry has formed a complete industrial system and categories. However, compared with developed countries, compared with the requirements of social development, national economic growth and the continuous change and upgrading of export packaging, there is still a big gap in quality and variety, technical content of new products, packaging and export capacity, technological development level and scale layout, talent and so on, Lack of stamina for sustainable development. It is mainly reflected in:

1. The enterprise scale is small and the industrial concentration is low

at present, there are about 1500 metal packaging enterprises in China, with an annual consumption of nearly 1.45 million tons of tinplate. Among them, there are less than 60 enterprises with more than 10000 tons, accounting for only 4%, and the average annual consumption of each enterprise is only 1200 tons of tinplate. Such as the largest COFCO packaging (Hangzhou COFCO Meite, Wuxi Huapeng bottle cap, Guangzhou Panyu Meite: the annual consumption of tinplate is only 75000 tons, with an output and sales of 800million yuan, which is far from that of developed countries. In addition, enterprises have not yet got rid of the situation of high input, high consumption, high pollution, low output and extensive management. For example, metal printing products, most of the foreign countries have popularized UV multi-color continuous high-speed printing iron through transformation, while China still stays in the traditional printing of monochrome, two-color and oil-gas drying room Iron way, low efficiency, high consumption, environmental pollution, the situation unchanged for decades, and the current international iron printing field to implement the development of "Prepress digital networking, printing multi-color continuous and efficient, post press diversification and automation". 5. Compared with the requirements of mold size and manufacturing tolerance, it is obviously in a backward state, lacking the advantage of international competition. In terms of barrel making, foreign countries have popularized ultra-thin iron cans, micro winding technology, special-shaped cans, flexible production schemes, etc. The wall thickness of can making is reduced to 0.07 ~ 0.13MM, which greatly saves materials and reduces resource consumption, changes the old face of a single cylindrical tank, and develops fashionable and diverse shaped tanks. However, most of the tinplate cans with a diameter of more than 0.20mm are still used in China, and the development of special-shaped cans is still in the stage of research and development and market test, which is relatively backward

2. There is a serious overcapacity of general products, and the production capacity of high-quality and high-end products is obviously insufficient.

at present, there are 26 production lines of two-piece cans in China, with an annual processing capacity of 11billion, while the actual demand is only 7billion, and the construction is insufficient; There are more than 200 production lines for three piece cans, with a speed of 400 ~ 1200 cans per minute. The comprehensive production capacity is 25billion cans per year, while the actual demand is only 8billion, and the supply-demand ratio is 3:1; There are nearly 300 crown cover equipment, half of which are imported and half of which are domestic. The speed is 110000, 140000 and 27000 hours respectively. The total annual production capacity reaches 75billion, while the actual demand is only 40billion, and the supply-demand ratio is 2:1. Only these three items show the severity of excess production capacity and repeated investment of general products. But on the other hand, there are too few enterprises that can produce small capacity, ultra-thin cans, self heating and self cooling cans, various special-shaped cans and boutique cans suitable for supermarket shelf effects. The shape of cans is single and unchanged for decades, which is difficult to meet the requirements of packaging fashion development, and restricts the development of metal packaging industry

3. The ability of independent innovation is insufficient, and advanced equipment is impacted and restrained by multinational companies.

since the 1990s, the metal packaging industry has developed vigorously, and a large number of foreign advanced production lines have been introduced. However, the domestic R & D capacity is insufficient, and most advanced can making enterprises can only rely on imports for their main iron printing and can making equipment, such as high-speed resistance welding machines and leak detectors for can making, easy pull cap crown cap production lines, iron printing equipment, etc., which are controlled by foreign enterprises. Substantial progress has been made in the localization of metal packaging materials such as tinplate. Baosteel has developed tinplate and tinplate that can meet the requirements of domestic can making and has been recognized by the market. However, the total amount can not keep up with the development needs of the metal packaging industry. The domestic capacity only accounts for one third of the national demand, and the remaining two thirds need to be imported from abroad; Aluminum materials for high-speed two-piece cans still need to be imported up to US $300million a year. At present, the main metal packaging equipment in the world is developing in the direction of digitalization, networking, high-speed and low consumption, and more environmental protection and humanization. The equipment level has been raised to a new level, and the gap between China and foreign countries that has been narrowed is widening

4. The degree of enterprise informatization is low, and there is a serious shortage of packaging management and technical personnel.

on the whole, the quality of senior management and staff in China's metal packaging industry is generally lower than that in other industries. The shortage of talents restricts the further development of the metal packaging industry, unable to track the world's advanced technology, and the ability to develop and innovate independent advanced technology and products is seriously insufficient

the above problems have seriously restricted the sustainable development and competitiveness of the metal packaging industry, and also affected the sustained, rapid, coordinated and healthy development of related industries. The lagging development of the metal packaging industry and the slow improvement of the overall level will definitely restrict the development of the whole economy. Therefore, we must take strong measures to build a modern metal packaging industry with high scientific and technological content, good economic benefits, low resource consumption, less environmental pollution and full play of human resources as soon as possible, so as to make China move from the current large metal packaging country to a powerful metal packaging country

metal packaging has great potential

metal packaging is an important part of China's packaging industry, and its output value accounts for about 10% of the total output value of China's packaging industry, mainly providing packaging services for food, cans, beverages, fats, chemicals, pharmaceuticals, cosmetics and other industries. Metal containers flourished from the late 1980s to the mid-1990s. In recent years, with the development of technology and the strengthening of industry management, the market order has led the company to further improve its unprecedented production capacity of automotive composite materials in an innovative way, and will gradually enter a stable and orderly period of benign development

metal packaging has the characteristics of capital intensive, technology intensive, domestic demand oriented, export-oriented, high product substitution, large seasonal changes in the market, and high market concentration. Metal packaging products can be divided into printed iron products (cans, boxes), cans (including aluminum two-piece cans, steel two-piece cans, 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). There are also chemical barrels made of 1-18 liters of sheet metal and 20-200 liters of steel barrels made of cold rolled sheet and zinc sheet

at present, the equipment of China's metal container manufacturing industry has strong strength. There are 26 production lines for two-piece cans, with an annual production capacity of more than 12 billion (the current market demand is about 7 billion). Tinplate three piece can manufacturing equipment has more than 500 imported and domestic full-automatic resistance welding machines of various models, and its products supply about 4billion in the beverage industry and about 3.8 billion in the food canning industry a year. The annual output of aerosol cans can reach 600million. There are more than 200 crown cap production lines in China, and more than 90% of the equipment is imported from abroad, with an annual market demand of 35billion. The annual processing capacity of steel barrels is about 40 ~ 50 million. Iron printing equipment has more than 400 production lines across the country, with half imported equipment and half domestic equipment, printing more than 15 billion times a year. The annual demand for tinplate in the whole industry is about 1.4 million tons. 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 tinplate three piece can manufacturing equipment has more than 500 imported and domestic full-automatic or semi-automatic production lines of various models. Its products supply about 4billion in the beverage industry and about 3.8 billion in the food can industry a year. The annual production capacity of aerosol cans reaches 600million. There are nearly 300 crown cap production lines in China, more than 90% of the equipment is imported from abroad, and the annual market demand is 40billion. The annual processing capacity of steel barrels is about 40 ~ 50 million. 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

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. With the continuous development of China's national economy and the continuous growth of people's consumption, the rapid development of upstream related industries will push the metal packaging industry out of the trough

at present, the beverage industry is developing rapidly. Although plastic bottles, glass bottles, composite paper bags and other packaging occupy a certain share, two-piece cans and three piece cans still occupy an advantage. For example, the beer market share of metal cans is growing. The demand for metal barrels and cans in oil and chemical industry, petroleum products, medicine, cosmetics and other industries will grow exponentially. In 2001, the total output of metal packaging products reached 2.05 million tons (including hot and cold plates), which is expected to reach 2.88 million tons by 2005. At the beginning of the new century, China has joined the WTO. The metal packaging industry should improve its industrialization level, improve its comprehensive strength, grasp the opportunity of the western development, and jointly create a broad space for benign development

in terms of per capita consumption, the domestic metal packaging market still has great potential. At present, about 410billion metal cans are produced in the world every year. Among them, there are about 320billion beverage cans, 75billion food cans and 10billion spray cans; The annual sales of beverage cans and food cans in Europe are 33billion and 27billion respectively; The growth rates of the sales of beverage cans and food cans in Asia in the past 10 years are: 250% for two pieces of beverage cans, 63% for three pieces of beverage cans and 71% for food cans respectively; The annual consumption of beverage cans in China is 11billion cans (7billion two-piece cans and 4billion three-piece cans), and the per capita consumption is less than 8 cans, while the annual consumption in Japan is 18billion cans and that in South Korea 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 water absorption of Chinese canned food is too low, and the consumption level of food is low, with an average annual consumption of less than 1.5 kg per capita. The average annual consumption level of canned food in Europe is 50 kg, and that of Japanese is 23 kg. At present, the domestic 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

development direction

first, establish domestic brands, promote strong alliances, and enhance the competitiveness of enterprises

secondly, China's metal packaging empty can technology has approached the international level. At present, efforts should be made to improve product quality, use ultra-thin tinplate and aluminum, carry out technological transformation and develop new products

in addition, we should solve the most important problems of food and beverage cans, such as leaking cans, easy to open the cover and easy to damage the pull ring, and make great efforts to improve the quality of various products
