The tinplate layer on the surface of tinplate sheet has good chemical stability and usually does not react chemically with food or beverages. This is because tin has extremely low reactivity at room temperature and is not easy to react with acids and alkalis, so it is widely used in food packaging.

According to industry statistics, in the global canning industry, more than 60% of packaging cans use tinplate materials. This ratio is even higher in certain areas such as food cans and beverage packaging.

The common manufacturing material for cookie tin packaging is tinplate, which not only has good mechanical strength and corrosion resistance, but also can provide excellent decorative effects for the can body.

if the food in the can is highly acidic or the food is stored for too long, in some extreme cases, tin may dissolve in trace amounts. Even so, the amount of tin dissolved is usually very small and not enough to pose a threat to human health.
