How long can paper tea packaging boxes be kept?

If the environment is suitable, it can be preserved for about one year. Paper is difficult to keep, because it is easy to get wet, and then it will penetrate into tea bags, destroying the quality of tea. However, as long as the tea leaves are stored in a dry and ventilated environment, away from water sources, and the paper tea bags are breathable, it is easy to make the fragrance of tea leaves disappear. Therefore, tea packaged in paper should be drunk as soon as possible.
