History of TIN CAN in China? Global form of tin can in 2020

     The production of metal packaging materials in China is relatively backward, but it has developed rapidly in recent years. With the expansion of production capacity of modern iron and steel enterprises such as Wuhan Iron and Steel and Shanghai Iron and Steel, the output and quality of tinplate have been greatly improved; two-piece can aluminum alloy sheets and flexible packaging composite aluminum foil have been developed. Although China's canning industry started late and the tinplate canning industry was established in the 1940s, it has developed rapidly in the past decade.In the 1970s, China introduced the British three-piece can production line and iron printing equipment. Several canning production lines were established. At present, the process of seam welding cans has gradually replaced the soldering process, and the quality of metal cans has improved accordingly, and the production of two-piece cans is being steadily developed according to needs and possibly.

The degree of mechanization of China's barrel making industry is not high, and some homemade or imitation steel barrel equipment needs to be technically modified to appropriately introduce steel barrel production lines or partly introduce crimping, welding and sealing equipment, and cap making equipment.

   Aluminum containers and composite aluminum foil bags are being further developed.

   In short, with the rapid development of the packaging industry and the increasing demand for metal packaging materials, the output and quality of metal packaging materials and containers in our country will be greatly improved.

In recent years, countries around the world are increasingly strict on the quality of metal packaging materials based on concerns about consumer interests and environmental protection. For example, the number of heavy metal testing projects is increasing. Therefore, efforts are being made to develop new metal packaging materials, develop new types of containers, change traditional canning processes and equipment, reduce environmental pollution and improve the hygienic level of packaged foods. The current development trend is: metal packaging materials are developing in the direction of light weight, thin plating, little or no surface treatment and compounding with polymer materials; metal packaging containers are developing in the direction of thin-walled lightweight and diversified types.

   In short, the output and quality of the metal packaging industry will be greatly improved in 2020. The world will usher in a new peak period of production, sales and consumption!
