Tin box with hinge manufacturers tell you that tin boxes, and miscellaneous cans-(non-standard cans, non-welded cans) can be adjusted according to their own products due to the structure and size of such tin cans, so there is no relevant national standard.

Introduction of raw materials: The tin box with hinge manufacturer tells you that the raw material used in the tin box is tinplate. A tinplate is an iron sheet plated with a layer of tin on the surface, which is not easy to rust, also known as tin-plated iron.
Tin box with hinge manufacturers tell you that in order to reduce production costs, not all tinplate surfaces are tinned, and the sheets without tinning are called substrates. Some substrates are galvanized or chrome-plated, unlike tinned iron, which is a thin steel sheet that is not tinned. Since tin is a precious metal, both chromium and zinc are cheaper than tin. If the surface of the tinplate is not plated with tin foil, the most obvious thing is to reduce the production cost. 
Tin box with hinge manufacturers tell you that according to the different requirements of the packaging industry, the thickness of the tinplate material, the amount of tin plating, and the mechanical properties have different needs. Since its inception, tinplate has been developing in the direction of using less tin, or even not using tin, and reducing the thickness of the tinplate substrate. The purpose is to adapt to changes in canned products and reduce the cost of canning.
The above information is a tin box with hinge manufacturer's introduction and analysis of the characteristics of the tin box, hope it helps you.
