Why print the inside of such a tin box and what is the effect?

In fact, the special material applied in the tin box packaging is used to prevent the contents of the packaging from corroding the tin box, prevent the wall from being contaminated, and better extend the storage time of the goods.It can be clearly seen on the curling edge of the food tin box that the application of decorative coating is not only to prevent corrosion, but also to protect the tin box from external scratches and rust.In addition, this kind of paint can add some beauty to the tinplate box.

The applied coating is non-toxic, harmless, odorless, has good adhesion, good absorption, good flexibility, and good corrosion resistance. It will not produce harmful materials when heated at low temperatures and will not lose the original luster.What exactly is this paint on the outside? In fact, such coatings include phenolic resin coatings, epoxy-phenolic resin coatings, acrylic resin coatings, aluminum powder coatings and so on.Finally, the surface or internal coating of the iron box packaging prevents oxidation of the intermediate layer and protects the iron box from rust.When we studied the ingredients of the packaging, we discovered this kind of chemical ingredients that prevent destructiveness.At the same time, to a certain extent, improve the beauty of the iron box packaging, which will provide consumers with protection and feel more assured of the quality of the product when purchasing the product.
