First of all, the material of the tinplate can is tin-plated sheet steel. Due to the different metal properties of iron and tin, the two metals are prone to oxidation reactions under natural conditions, causing the iron sheet to corrode and rust. Unlike the finished iron box packaging, the two metals are prone to oxidation reactions under natural conditions, causing the iron sheet to corrode and rust. And for the finished printing on tin cans packaging, there is basically no need to worry about this problem, because before the tinplate can is formed, the tinplate will be treated with rust. One is printing and varnishing, which not only beautifies the tinplate can, but also uses the printing ink and the varnish on the surface have been double-layered to protect the iron material; the other is a plain tinplate can, and the varnish is directly applied without printing. Both of these methods effectively isolate the iron material from contact with moisture in the air, and slow down the oxidation rate of the iron material.
In addition, when using or storing, you should be careful not to put it in a humid environment. At the same time, handle the printing on tin cans gently to avoid damaging the paint printing on the surface of the metal plate printing box. Secondly, you can use furniture wax, shoe polish, and floor wax at home to wipe the metal plate printing can , repeating it every interval. Applying anti-rust paint or metal curing agent once on the surface of the metal plate printing box can effectively avoid direct contact between the tinplate and the air.
