Tinplate boxes are used as packaging that is not currently a commodity. In addition, they have been reused as metal cans for storing items, such as tea, wolfberry, dried fruit, etc. However, we must pay attention to the tightness of the tin can when we use to store these edible items. Below we look at three methods of sealing tinplate boxes.

Either way to improve the airtightness of the tinplate box is to isolate the air from contact with food. We only need to make good use of this principle to use iron cans to store items.
High-temperature heating exhaust, when packaging meat-based foods, generally use high temperature of 80-90 degrees Celsius to quickly evacuate the air and seal it in a short time. The products of vegetables and fruits must be exhausted at a temperature of 60-75 degrees Celsius for a long time until the proper vacuum is reached in the tank.
Vacuum compressed air is placed in a special vacuum sealing machine when the food is to be sealed. The pressure in the vacuum is used to compress the air in the tank. Vacuum treatment can also avoid the residue of bacteria and microorganisms. This method will not be limited by the heating of food. It is one of the most used methods now.
Steam expels the air. This method sprays steam into the package to expel the air in the tank. After the air is exhausted, the steam in the tube is condensed to achieve the vacuum effect. This method is more economical and convenient, but it is subject to restrictions on the application of the goods.
