Generally speaking, the shelf life of canned food ranges from 1 to 5 years, and the role of tinplate cans is to protect the food from the influence of the external environment during this shelf life and maintain the flavor and safety of the food.

In the field of food and beverage packaging, tinplate sheet is usually used to make cans, beverage cans, etc. The service life of such products is generally 2 to 5 years. This is mainly because food and beverages have a short shelf life, and the environment inside the can is usually oxygen-free, which helps to extend the service life of tinplate sheet.
