Canned food is processed and sealed in sealed containers(Mason cans, steel cans and tin cans) for long-term preservation. The average shelf life of cans is 1 to 5 years, but may be longer in some cases.
Freeze drying can reduce the growth risk of bacteria and extend the shelf life. Therefore, canned dried soybean products(such as dried soybeans) can be used for 30 years under edible conditions.

Aluminum and tin are highly flexible metals. They are not only anti-corrosion, but also easy to process.
