Metal packaging container products mainly provide supporting services for related industries such as canned food, various beverages, wine, medicine, oleochemicals, petroleum products and cosmetics. After 30 years of reform and opening up, my country’s metal packaging industry has formed a complete metal packaging industrial system that includes printed iron cans, two-piece cans, steel drums, bottle caps, and aerosol cans. It has become an important category of China’s packaging industry. One. The metal packaging industry has annual sales of more than 5 million yuan, and there are a total of 555 enterprises of a certain scale, showing a three-pronged pattern of state-owned, foreign-funded and private. In recent years, private enterprises have developed rapidly, and some have formed enterprise groups of a certain scale. However, from the perspective of the entire industry, small and medium-sized enterprises account for more than 90%. The situation of small and scattered, small and complete has not been fundamentally resolved. The task of intensive industrial integration remains arduous. Regional distribution of metal packaging companies: more than 70% of the companies are located in the Pearl River Delta (Guangzhou, Zhuhai, Shenzhen, Hainan), the Yangtze River Delta (Jiangsu, Zhejiang, Shanghai) and the Jingjintang Bohai Bay Economic Zone. In addition, Sichuan, Fujian, and Shandong rely on the advantages of deep processing of agricultural and sideline products to drive the development of metal packaging.

　　Tinplate packaging container has many advantages such as high strength, good formability, and strong compatibility with products. Therefore, in the first two centuries, countries have generally paid attention to this kind of packaging container. It is the most used metal packaging board. Due to the continuous improvement and perfection of tinplate printing technology and processing technology, tinplate packaging is more and more widely used. With the improvement of domestic tinplate production capacity, tinplate imports will gradually decrease, and soon it will be self-sufficient, but some high-end products still need a small amount of imports. Since its inception, tinplate has been developing in the direction of thinning. One is to use less tin, or even not to use tin, and the other is to reduce the thickness of the tinplate substrate. The purpose is to adapt to changes in canning products and reduce the cost of canning. The tinplate for packaging can no longer use ordinary tinplate, because it is not only wasteful, but also difficult to make profits. According to the different requirements of the packaging industry, the thickness of tinplate materials, the amount of tin plating, and mechanical properties have different needs. Manufacturing tinplate for packaging containers will be a direction for the development of the steel industry.

　　The demand for metal packaging has a very broad future, and the demand is large, and the tinplate packaging container will become larger and larger. In 2008, the sustained and rapid development of the food industry brought a broad market development space for the tinplate packaging container industry. The demand of my country's packaging industry puts forward higher requirements for metal packaging not only in terms of quantity and quality. During the "Eleventh Five-Year Plan" period, my country’s packaging industry will continue to grow rapidly. By 2010, my country’s packaging industry market will exceed 500 billion yuan, and metal packaging is expected to reach about 50 billion yuan. During the growth opportunity period, metal packaging products are abundant, application fields are very broad, and there is huge room for development.
