Is it tinplate or sun bottom?

Tinplate is good. The bottom of the sun is pirated, mostly plastic skin and iron inner shell, while the official Japanese products are basically tin, so tinplate is good. Tinplate is an iron sheet with a layer of tin on its surface, which is not easy to rust. It is also called tinned iron. The word "Baji" comes from the homonym of "badge" in Japanese. Refers to the badge around the animation.
