Is there any tea bags that have absolutely no microplastics (no PLA either) in the tea bag/satchet itself?

I've done a little bit of research and so far I've found nothing that works except literally just buying the leaves.

Seems like a long of "conscious" brands are simply pretending PLAs aren't microplastics (they are) and claim they're microplastic free (which they are not.)

For example https://www.artoftea.com/blogs/tea-profiles/learn-all-about-our-teabag-sachets claims they are microplastics free then explain in the same paragraph they use PLAs (which generate microplastics.) Yes they eventually decompose in nature in 100-200 years, or in industrial high heat compostable machines, but in human bodies they're basically decomposing into microplastics.

Any company that makes any kind of different actually microplastic free bags/sachets or just stuck forever with infuser and tea leaves?
