Tin boxes can also be corroded

Tin box corrosion refers to the corrosion of the tin box surface by oxygen, water or chemical substances.Tin box is a ferritic stainless steel with good corrosion resistance.However, under certain circumstances, tin boxes may also suffer from corrosion.
                                                                                                                 
1. Frequent contact with water or long-term exposure to humid air.
2. The surface protective layer is damaged or scratched.
3. Contact with corrosive items.
In a humid environment, the air contains a large amount of water molecules, and the tin box oxidizes and rusts.Tin boxes can also easily rust due to improper use, storage or other reasons, thus affecting their appearance and overall performance.However, tin box made of tinplate are a special case. Some finished tin boxes will be tin-plated and coated with anti-rust varnish before printing. Coupled with the protection of ink, the tinplate has been separated from the air and can be used normally. In this case, rust will not easily occur.
