Tinplate printing ink has good adhesion and mechanical properties. The surface of the substrate printed by tinplate is very smooth and does not have absorption ability, so tinplate printing ink should have good adhesion. At the same time, tinplate prints are generally not final products. Tinplate printing must be made into various food cans, toys, metal boxes, and barrels and cans of chemical products. Printed tinplate need to undergo cutting, bending, stretching, forming and other processes. So the tinplate printing ink has strong mechanical properties.
