The role of tinplate surface ink
The ink on the surface of the tinplate is different depending on the contents of the iron box. The ink used in the Food Tin Box must reach the food grade, while the medicine tin box has stricter requirements on the ink.
The reason why there is a layer of ink on the surface of the tinplate is as follows:
1. Insulate the contact between the material of the tinplate itself and the air to prevent oxidation and rust of the iron box.
2. Increase the water resistance of the tinplate to prevent moisture in the air from penetrating into the iron box.
3. Increase the metallic luster and smoothness of the tinplate.
