Because of its good sealing, preservation, light-shielding, sturdiness and unique metal decorative charm, tinplate packaging has a wide coverage in the packaging container industry and is a universal packaging variety. With the continuous enrichment of various CC materials, DR materials, and chrome-plated tinplate, which has promoted the development of packaging products and technology, tinplate packaging is full of innovation everywhere.
Many advantages such as high strength, good formability, and strong product compatibility for tinplate packaging containers have established a good reputation in the international market. Therefore, all countries attach great importance to this kind of packaging container, which is the largest amount of metal packaging sheet in the world.
According to the different requirements of the packaging industry, the thickness, tin plating amount, and mechanical properties of tinplate materials have different needs. Since its inception, tinplate has been developing in the direction of thinning. One is to use less tin or even tin, and one is to reduce the thickness of the tinplate substrate. The purpose is to adapt to changes in canning products and reduce canning costs.
With the continuous improvement and improvement of tinplate printing technology and processing technology, the application of tinplate packaging is becoming more and more widespread. At present, China's tinplate production capacity continues to increase, and tinplate imports will gradually decrease. In addition to the need for a small amount of imports of some high-end products, self-sufficiency has been basically achieved. The demand of China's packaging industry has put forward higher requirements on the quantity and quality of metal packaging. In 2010, China's metal packaging container sales revenue exceeded 50 billion yuan, which also made metal packaging into a new growth.
