Frequently asked questions about custom tin boxes

   Answer: Tinplate is a tin sheet wrapped in tin. Because of the stability of tin, tinplate can be used in a variety of packaging, and because of the metal texture, fashion, safety and convenience, more and more people choose tinplate packaging. The chemical nature of tin is stable and not easily rusted, so tinplate will be tinned. This will ensure that some of the packaged products will not be affected and can be well preserved.

But tin is afraid of cold and heat, the melting point of tin is very low, and it quickly turns into a liquid in the fire. Therefore, tinplate packaging generally cannot be burned at high temperature, because high temperature burning will melt the tin coat on the outside, and the iron sheet inside will not have a protective effect, so the tinplate box that is generally burned will quickly rust and corrode. Tin is afraid of cold and begins to lose ductility at a temperature of about 13 degrees. When the temperature is lowered again, it will reach minus 30 degrees, tin will turn into powder. If you hear it correctly, it will turn into powder. Moreover, this property of tin is easy to infect, and good tin will also become powder when it touches into powder. This phenomenon is called "tin plague". Also, tin has a low hardness and can easily break. If the knife cuts the tinplate skin, the patch inside will slowly be eroded away. Therefore, protecting tin can protect tinplate from corrosion. This is why tinplate needs to be tinned.

The tin plating solution used in tinplate tin plating now depends on whether the tin plating solution is good or bad.
