Standard for Painting and Printing of Coatings inside Tin Boxes

A tin box usually needs to be coated with a certain coating on its surface, with the aim of preventing the chemical interaction between the substances inside the box and the wall of the box, as well as the pollution of trace harmful substances on the substances inside the box, and protecting the freshness and original flavor of the substances inside the box.
The coating principle of the inner surface of the iron box is to use a roller coating machine to print and apply the appropriate coating onto the smooth surface of the tin plate before cutting it into the can body blank, in a uniform and controllable thickness coating.
Tin box packaging has a long history of becoming the leader in food packaging, and its effectiveness is largely attributed to the important protective effect of internal coatings. The performance of the coating should not only have corrosion resistance, but also have good adhesion, softness and toughness, non-toxic and odorless.
