Why is tea packaged in iron boxes and cans?

The main reason why tea leaves spoil is because they are not tightly sealed, allowing the tea leaves to absorb moisture and odors from the air, or because light shining on the tea leaves causes them to lose their original flavor. The more precious the tea, the easier it is to lose its flavor. Storing in iron cans can effectively solve this problem. The iron jar packaging is tightly sealed, which can effectively block the contact between tea leaves and air, and has good effects on moisture resistance, oxidation resistance, light resistance, and odor prevention. At the same time, the iron jar itself has no odor and will not affect the original fragrance of the tea leaves.

To ensure that tea does not spoil, place the tea leaves in an iron can, tightly cover the lid, and place the iron can in a cool place. This not only prevents the iron box from rusting, but also slows down the rate of tea aging and deterioration. The tea leaves stored in this way, no matter how long they are stored, will still be fragrant and refreshing when they are taken out and steeped again. Do you know why tea is packaged in iron boxes.
