1. The market structure of my country's metal packaging
Among the metal packaging, tinplate packaging is the main one. Due to the continuous improvement and perfection of tinplate printing technology and processing technology, tinplate packaging is more and more widely used. As the production capacity of domestic tinplate increases, tinplate imports will gradually decrease, and it will soon be self-sufficient, but some high-end products still need a small amount of imports.
metal packaging products can be subdivided into printed iron products (tins, boxes), cans (including aluminum two-piece, steel two-piece, and tinplate three-piece cans), aerosol cans (tinplate made of exquisite medicinal cans, pesticides Cans, cosmetic cans, etc.), food cans (canned food, liquid or solid food cans, etc.) and various bottle caps (horse crown caps, screw-open caps, aluminum anti-theft caps). There are also chemical barrels made of 1-18L tinplate and 20-200L steel drums made of cold-rolled sheets and zinc sheets.
At present, China's metal packaging market is showing a trend of oversupply, but from the analysis of per capita consumption, there is still a lot of room for development. The annual consumption of beverage cans in China is 11 billion cans (7 billion two-piece cans and 4 billion three-piece cans), and the per capita consumption is less than 8 cans, while Japan’s annual consumption is 18 billion cans and South Korea’s is 3.2 billion cans. If China's annual per capita consumption is increased to 10 cans, it will require a supply capacity of 13 billion cans per year; in addition, the consumption level of canned food in China is low, with per capita annual consumption less than 1.5 kg, and the per capita annual consumption level of canned food in Europe is 50 kg. The average annual consumption level is 23kg.
1. Lack of high-end products
2. Low industrial concentration
3. Excessive dependence on imports
4. Serious waste of resources
2. Pre-coated steel plate technology for foreign metal packaging
Coated steel plates are generally produced intensively by metallurgical公司。涂装工艺的the production of products is omitted, the cost of packaging manufacturing is greatly reduced. It is estimated that the cost of packaging products using thin steel plates as raw materials can be reduced by 5-10%, saving energy by about 1/6-1/5, especially saving a large amount of investment in pretreatment of packaging products and coating equipment. Coated steel plate has the advantages of both organic polymer and steel plate. It not only has the good coloring, formability, and corrosion resistance of organic polymer, but also the high strength and easy processing of steel plate, which can be easily punched. , Bending, deep drawing, welding and other processing.
3. The appearance of pre-coated tinplate is smooth, smooth, decorative, and feel good, and the cost of pre-coated tinplate is lower
1. Because it is continuous production, under normal circumstances, it is not necessary to use tinplate as the base material for production. The cost advantage of cold-rolled coil coating is obvious.
2. The production of pre-coated tinplate is a continuous and high-speed production line for coiling. Compared with the traditional printing process, the production speed is faster.
3. The production process of pre-coated tinplate can be completed at one time due to the printing and pre-coating process. Compared with the traditional printing process, it has the characteristics of low energy consumption, high speed and less materials.
