Due to its good sealing, preservation, light protection, solidity and unique metal decoration charm, tinplate packaging has a wide coverage in the packaging container industry and is an internationally accepted packaging variety. With the continuous enrichment of various CC materials, DR materials and chrome plated iron tinplate, which has promoted the development of packaging products and technology, tinplate packaging is full of innovation everywhere.

Because of its strong oxidation resistance, diverse styles and exquisite printing, tinplate packaging containers are deeply loved by customers, and are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, industrial packaging and other aspects.

Many advantages such as high strength, good formability, and strong compatibility with products of tinplate packaging containers have established a good "reputation" in the international market. Therefore, all countries generally attach importance to this kind of packaging container, which is the world's largest metal packaging plate.

According to the different requirements of the packaging industry, the thickness, tin plating amount, mechanical properties, etc. of tinplate materials have different needs. Since its inception, tinplate has been moving in the direction of thinning. One is to use less tin, or even no tin, and the other is to reduce the thickness of the substrate of tinplate. Its purpose is to adapt to changes in can making products and reduce the cost of can making.

With the continuous improvement and perfection of tinplate printing technology and processing technology, the application of tinplate packaging is becoming more and more extensive. At present, the production capacity of domestic tinplate continues to improve, and the import of tinplate will gradually decrease, except for some high-end products, a small amount of imports are still required, and self-sufficiency has been basically achieved. The demand of China's packaging industry has put forward higher requirements for metal packaging in terms of quantity and quality. In 2010, China's metal packaging container sales revenue exceeded 50 billion yuan, but also made metal packaging into a new growth opportunity period, the sustained and rapid development of the food industry for the tinplate packaging container industry to bring a broad market development space.
