How long can tea leaves packaged in vacuum bags last?

Tea is not only popular in our country, but also very popular in other countries. However, due to the characteristics of tea, the aroma is easy to volatilize, and the tea has a strong adsorption force for moisture and odor. If it is improperly stored, it is easy to absorb moisture and damp, resulting in qualitative change and loss of its proper commercial value. Therefore, most of the tea is preserved in vacuum packaging bags, So, how long can the tea leaves in vacuum-packed bags be stored? I believe that everyone is very curious about this question, and then let me reveal the secret to you.

Most of the tea is fermented, so the shelf life is generally about three months. If it is vacuum packed, placed in a cool place, and protected from light, the shelf life can be as long as two years. Twenty years, it can even be put into old tea.

Of course, the use of vacuum bags to package tea, to effectively extend the shelf life of tea, is directly related to the material of the vacuum bag.
