These days there is no "paper tea bag". Even the paper ones have a nontrivial amount of PLA plastic embedded in them, enough to cause acid reflux and allergic reactions. It is added to diminish the risk of tearing. Just do yourself a favor, throw them away, and use loose leaf.

for tea I use metallic container, but for that you can't use powder tea, you need dried leafs... which I think are also better
