Custom Tinplate Long Round Iron Box

Because before the iron box is formed, the Tinplate iron box will be rust-proof. One is to add varnish to the printing, which not only beautifies the iron box, but also uses the ink used for printing and the varnish on the surface to carry out double-layer protection treatment on the iron material; The other is plain iron box, which is directly coated with varnish without printing. Both of these methods have effectively isolated the contact between iron and moisture in the air, and slowed down the oxidation rate of iron. However, if there is rusting, it means that your tin-box product is placed in a humid environment. In a humid environment, the air contains a large amount of water molecules, and the iron and it oxidize and rust. Another reason is that your iron box product is damaged. The scratch or friction causes the surface to lose the protection of the ink, and the iron material is exposed to the air, which then causes the oxidation and rust of the Tin Box.
