  Treatment method of tin can surface blackening:

 

  Tin cans refer to metal crafts made from tin as raw material. Chinese tin cans began in the Yongle period of the Ming Dynasty and were mainly produced in Yunnan, Guangdong, Shandong, Fujian and other places. Among them, the one produced in Gejiu, Yunnan is the most famous. In the 1950s, a specialized tin can factory was established in Gejiu City. Tin cans have developed a lot, and some products are sold abroad.

 

  For a long time, high-end tea has been packaged in tin cans. Tin cans for storing tea have been recognized as the best container for long-term preservation of tea since ancient times. Usually, paper tea cans and iron tea cans are used to store tea. Because of the poor sealing effect, the freshness of the tea is very short-lived. Especially in high humidity, high temperature or dry climates, tea leaves deteriorate faster. Tests have proved that tea leaves will absorb enough moisture when exposed to moist air for one hour and become soft and deteriorate.

 

  The production process of tin cans mainly includes melting, casting, modeling, cutting, scraping, welding, polishing, decoration, engraving and other processes, most of which are manual operations. Tin cans can be widely used and loved by people precisely because of the excellent characteristics of tin itself. For example, tin tinplate is widely used in food packaging, and high-end chocolate is wrapped in tin foil.
