Metal materials such as tin-plated steel sheets and aluminum are suitable for high-end candy tin boxes, with good protection and aesthetics; plastic materials such as polyethylene and polypropylene are suitable for economical candy tin boxes, with the advantages of low cost and good processability.

Authoritative organizations such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have strictly regulated and certified the food contact materials of tin boxes to ensure that they meet food safety standards.

Some special-purpose tin boxes, such as packaging boxes for cosmetics, medicines and electronic products, usually require special sealing properties and anti-corrosion treatment. The production process of this type of tin box is more stringent, and the price is generally between $10 and $50 each.

In fact, the vast majority of so-called "tin cans" are not made of pure tin, but of tinplate. Tinplate is a composite material with a layer of tin on the surface of an iron plate. Pure tin is not common in real-world applications for the following reasons:

The sealing performance of tin cans is one of its main advantages. Through reasonable design, the tin can lid is tightly combined with the can body, which can effectively block air, moisture and microorganisms from entering the can, preventing food from getting damp, oxidized and deteriorating.
