Tinplate boxes and tin cans need to be printed on the tinplate before they are made, and then cut and stamped. Tinplate printing is commonly known as iron printing. It uses the physical properties of water and ink to repel each other, and with the help of printing pressure, the printing plate is transferred through the blanket.

The market is very popular to sell tinplate can packaging products, such as milk powder, drinks, gifts, snacks, tea, coffee, candles, candy and so on. Why are these products keen on tin packaging?

 The tea can should have good sealing performance, good moisture, light, odor and oxidation resistance. Such tea cans are good utensils for storing tea.

   The surface or internal coating of the tinplate box packaging can play a role in preventing oxidation, protecting the tinplate box from rusting, preventing damaging chemical components when packaging special contents, and enhancing the beauty of the tinplate box packaging to a certain extent, giving consumers a sense of security and more assured when purchasing products.

What kind of material is tinplate? It is actually a kind of steel. Under normal circumstances, the surface of iron exposed to the air will have active chemical properties, oxygen in a humid environment will continue to oxidize with water in the air, that is to say, iron in contact with the air will react chemically with oxygen in the air, when the oxygen in the air is dissolved in water, the molecules on the surface of iron will be transformed into iron oxide, which is what we often say is rust. That's why iron rusts.
