[ppzhan Abstract] With the development of the economy and the improvement of people's living standards,
Packaging has become a common part of daily life. However, because packaging often leads to food safety problems, people put forward higher requirements for packaging, and
Metal Packaging as a safe packaging has become a good idea for many consumers.
China's packaging industry includes seven sub-sectors: paper packaging, plastic packaging, metal packaging, glass packaging, packaging and printing, packaging machinery manufacturing and other packaging products. Among them, metal packaging is considered to be a safe packaging in the world because of its own attributes. Today, as food safety issues are increasingly valued, metal packaging will usher in the peak of development.
The development status of the metal packaging industry in China After 30 years of reform and opening up, China's economic and consumption growth has driven the growth of the packaging industry and the improvement of the quality of packaging products. Metal packaging is widely used in the food, beverage, daily chemical and household products industries due to its good sealing and bright patterns. The food and beverage industry has become a major market for metal packaging, and the chemical, cosmetics and pharmaceutical industries are important markets for metal packaging.
China's metal packaging industry has now formed a complete metal packaging industry system including printing and coating iron, cans, caps, barrels and other products. Its main products can be divided into: printed iron, beverage cans (including two aluminum beverage cans, two-piece beverage cans for steel, three-piece beverage cans for
Tinplate), food cans (general food cans and milk powder cans), aerosol cans (medical cans made of tinplate, insecticide cans, cosmetic cans, industrial and household care cans, etc.), chemical tanks, steel drums and metal lid products of 200 liters or more (crown cans, unscrewed cans, cans, etc.), The metal packaging product line is rich and the application field is very broad.
In recent years, China's metal packaging industry has entered a period of rapid development. In the past 10 years, the annual growth rate of China's beverage industry has been maintained at more than 20%. In 2011, the total output of China's beverages was 118 million tons. China's total canned food is 9.72 million tons, with sales of 120.2 billion yuan, including metal packaging, soft and hard packaging and other packaging products. With the improvement of national consumption power and the upgrading of consumption habits, and the rapid growth of beverage products, a large number of metal packaging materials have been used. However, from an international comparison, despite the rapid growth for 10 consecutive years, the per capita annual consumption of cans in China is only 17 cans, which is only equivalent to 1/22 of the US (380 cans). According to statistics, the annual consumption of canned Americans is about 90 kg, about 50 kg in Western Europe, 23 kg in Japan, and only 1 kg in China. As the domestic market has not been effectively activated, and the safety and convenience of metal packaging relative to glass packaging needs to be improved, the metal packaging market for canned food is incalculable, and there is a strong growth momentum.
According to experts' prediction, China's metal packaging industry has huge room for development in the next 3-5 years, and it is a foregone conclusion that it has exceeded 100 billion in output value. This is due to the continuous growth of food and fast-moving consumer goods, especially the rapid growth of beverages as consumer goods, the increasing rate of beer canning, the strong demand for two-piece cans in the rural market, the metal packaging machinery, management and capacity scale. Gradually improve, therefore, China's metal packaging industry will have a lot to do.
According to industry experts, the rapid growth of fast food consumption is the driving force for the rapid development of this industry. According to the information provided by the Beer Professional Committee of China Food Industry Association, in 2011, China's beer output reached 48.789 million tons, an increase of 10.7%; profit level, Tax growth is above 10%. In 2011, cans accounted for about 5% of the total beer, with nearly 5 billion cans a year. The beer canning rate in the United States, the United Kingdom, and Brazil has reached 52%, 49%, and 38%, and the market for beer cans is huge.
In the future, metal packaging will pay more attention to food safety, pay more attention to thinning and reduction, and pay more attention to recycling. The upgrade trend of packaging products directly increases the share of metal packaging products in various types of packaging products; about two-thirds of steel cans in the UK are made from recycled materials. In some European countries, the recycling rate of metal cans exceeds 90%. Therefore, new requirements are imposed on the steel for manufacturing metal packaging cans, such as metal packaging containers such as containers and ordinary steel drums, which have greater strength and rigidity, and have the advantages of low cost, good processing performance, and the like, and therefore require high steel plates. Strength and stiffness.
In addition, the packaging of weakly acidic foods requires certain corrosion resistance of the steel plates. Such foods are used in large quantities in the international market, such as meat, fish, poultry, dairy products, vegetables, carrots, peas, beets, potatoes, and Kinds of drinks, soups, etc. At present, chrome-plated steel sheets are mainly used in the production of beer caps, beverages and neutral food cans, and there are few food cans. This requires the steel sheet to have greater corrosion resistance.
Foreign countries attach great importance to the research and development of steel for metal packaging. For example, some steel companies in the UK put a new decorative steel plate on the market several years ago. This material consists of chrome plated steel plate and several layers of polymer coating film on its surface. It has been applied in Europe. This polymer spray material has several layers of composite film that can be metallized and can be printed with a holographic trademark. It has a protective layer that is good for printing. Since the entire process is carried out on a flat surface, this series of decorative steel sheets is ideal for decorative containers, easy-opening covers, twisted covers, crown caps, composite can end caps and three-piece cans. Due to the smooth and beautiful surface of this steel plate, the tinplate container market was opened as soon as it was published. There is a type of polymer coated steel used to make good barrier properties, corrosion resistance and eye-catching packaging. There is also a new coating process that directly extrudes the resin onto the steel sheet and is currently used in the production of food cans. Origen's three-piece beverage cans have been thinned and have successfully developed 0.12mm cans from a thickness of 0.20mm, which is at the forefront of the international metal packaging industry.
The development prospect of metal packaging industry in China In the future, China's metal packaging industry has broad prospects for development. The potential market for steel for metal packaging is huge. In China's 1,400 metal packaging enterprises, the annual consumption of tinplate is nearly 1.4 million tons. Future metal packaging focuses on reducing emissions, saving energy and reducing consumption, strengthening clean production, and creating green companies and green products. The consumption of metal packaging materials is high, and the proportion of cost is high. The development and research of “reduction” and “thinning” are emphasized. The focus is on the reduction rate of consumption of metal packaging materials, the reduction rate of consumption of auxiliary materials, and the reduction of energy consumption. Rate, reduction rate of consumption of public resources, utilization of waste materials, and material recycling during processing. Thinning and light weight, metal packaging materials development trend, more prominent metal packaging materials are safe, easy to process, green three significant features.
In addition, with the development of the economy, the packaging market's requirements for metal packaging are also becoming clearer and stricter. Experts suggest that in order to meet the needs of the development of the food fast-moving consumer goods industry, metal packaging enterprises should start from the following aspects to achieve the transformation and upgrading of the entire industry as soon as possible:
,safety. The concept of safety is not only for the safety of the container itself, but also for technical safety, environmental protection and safety. From an international perspective, metal packaging is safe, but there is still room for improvement. As consumers pay more attention to safety, and with the improvement of inspection methods, the concept of food safety in society is also expanding. It is necessary for the metal packaging industry to attach great importance to technology research and development, and continuously develop and improve new products that are conducive to food safety. Products, new technologies, new processes.
Second, economic. Advanced technology should be used to further enhance the competitiveness of metal packaging. The packaging industry is now entering an era of packaging diversification. Metal packaging, glass packaging, and flexible packaging have developed rapidly in recent years, and technology has also improved. In order to show their own characteristics, metal packaging should further adapt to the need to reduce the cost of end products in terms of cost increase. For example, in terms of new material selection and material reduction, there is still a large space for cost reduction.
Third, convenience. The so-called convenience is the convenience of the supermarket display in addition to the convenience of product packaging. In recent years, metal packaging has done a lot of work in this area, such as the development and application of packaging forms such as easy-to-open caps and magic cans. It should be said that convenience is the general trend of the future development of the metal packaging industry, and metal packaging companies have great potential in this regard.
