Often in the tea bag or package there is a small bag of moisture-proof agent.  What do you do with it after you open the tea bag?

First of all, it absorbs moisture and to keep tea leafs dried when they packed the tea in bag.

Once the bag is opened, tea leafs are once again engage with air.

  • If you have a vacuum packaging machine, then it’s OK to keep it in the bag.
  • If you don’t have the vacuum packaging machine, then it is better to take it out.

Because I don’t think you want your tea absorbs moisture just because this bag absorbs moisture in the air.
