About the maintenance of tinplate boxes
A tin box is a sheet of iron wrapped in tin. Due to the stability of tin, tinplate can be used in a variety of packaging. More and more people are choosing canned packaging due to its metallic texture, fashion and convenience. Tin is chemically stable and not easy to corrode, so it can be tinned. Only in this way can it be ensured that some products in the package will not be affected and can be stored properly.

But tin is afraid of heat and cold, and its melting point is very low, and it will soon turn into a liquid in fire. Therefore, tinplate packaging usually cannot be burned at high temperature, because high temperature combustion will melt the outer tin coating, and the inner iron sheet has no protective effect, so the usually burning tin box will quickly rust and corrode. Tin is cold and starts to lose ductility around 13 degrees. When the temperature drops to about minus 30 degrees again, the tin will turn to powder. You heard that right, it turns into powder. Also, this property of tin is contagious, and when good tin meets tin that has been powdered, good tin becomes powder. In addition, the hardness of tin is small, and it is easy to break. If the knife cuts through the tinplate skin, the patch inside will be slowly eroded away. Therefore, protecting the tin can well protect the tinplate from corrosion. This is why tinplate needs to be tinned. The tin plating solution used in tinplate tinplate now, the quality of the tinplate determines the degree of protection of the tinplate.
