Development of Tinplate in packing industry
According to the different requirements of the packaging industry, the thickness of tinplate material, the amount of tin plating, and the mechanical properties have different needs. 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. Its purpose is to adapt to changes in canning products and reduce the cost of canning.
With the continuous improvement and perfection of tinplate printing technology and processing technology, tinplate packaging has become more and more widely used. At present, the production capacity of domestically produced tinplate continues to increase, and the import of tinplate will gradually decrease. Except for some high-end products, a small amount of imports has been basically self-sufficient. The demand of my country’s packaging industry puts forward higher requirements on the quantity and quality of metal packaging. In 2010, my country’s metal packaging container sales revenue exceeded 50 billion yuan, which also brought metal packaging into a new growth opportunity period. The continuous and rapid development of the food industry has brought a broad market development space for the tinplate packaging container industry.
