Tinplate high value-added steel products, mainly for the packaging industry, due to its good sealing and preservation, avoid light, strong and unique metal decorative charm, determines its packaging container industry has extensive coverage, is the international general packaging varieties, application in packaging industry in our country is developing rapidly. Metal packaging container products mainly for canned food, beverage, wine, medicine, oil chemical industry, petroleum products and cosmetics related supporting services. Metal packaging industry in our country after reform and opening up 30 years of development, has been formed, including printing can, two piece cans, steel barrel, bottle caps, aerosol cans, as one of the complete system of metal packaging industry, as one of the important categories of China’s packaging industry. Annual sales of 5 million yuan of above, metal packaging industry has a certain scale, a total of 555 enterprises, state-owned, joint venture, private landscape of the three pillars of. In recent years, the rapid development of private enterprises, some enterprise group has formed a certain scale, but from the point of the whole industry, small and medium-sized enterprises accounted for more than 90%, small and scattered, the situation has not been fundamentally solved conveniently small, industrial intensive integration task is still arduous. The regional distribution of metal packaging enterprise: more than 70% of the enterprises in the pearl river delta (guangzhou, zhuhai, shenzhen, hainan), Yangtze river delta (jiangsu, zhejiang and Shanghai) and the beijing-tianjin-hebei bohai bay economic zone. In addition, sichuan, fujian, shandong rely on agricultural and sideline products deep processing advantages, promote the development of the metal packaging.
Tinplate packaging container has high strength and good formability, strong compatibility of products and many other advantages. So, two centuries ago, paid attention to by all countries in this kind of packing container. Is one of the most consumable metal packaging. Because of tinplate printing technology and processing technology of continuous improvement and improvement of tinplate packaging application is more and more widely. With the improvement of domestic tinplate production capacity, tinplate imports will reduce gradually, soon to be self-sufficient, but still needs a small amount of imports of high-grade products. Tin since its advent, has been developed to the direction of thinning. One is to use less tin tin or none at all, a is the substrate thickness thinning tinplate. The objective is to adapt to changes in the can product and reduce the cost of guangdong province. Packaging tin can no longer use common tinplate, because not only wasteful, and difficult to obtain profits. According to the different requirements of packaging industry, the thickness of tin, tin plating, mechanical properties and so on all have different needs, make special tinplate packaging container will be a direction of the development of the iron and steel industry. Metal packaging has a very wide range of future demand, demand is bigger, tinplate packaging container will be bigger. From 2011 to 2015, the sustained and rapid development of food industry for tinplate packaging container industry with broad market space for development. Packaging industry in our country, the demands of the metal packaging not only on the quantity and quality are put forward higher requirements.
