The Republic of Tea Round Tea Bags
The clever round bag with no string, tag, or staple - unbleached paper, but a heat-crimped seam the brand hasn't confirmed is thermoplastic-free.
The verdict: Minimal plastic contact
The signature round bag is a genuinely minimalist design: unbleached "tea paper" with no glue, no staple, no string, and no tag, and the company confirms no chlorine is used. The unresolved point is the seam. Glue-free, staple-free round bags of this style are commonly fused with a thermoplastic (polypropylene or PLA) melt fiber blended into the paper, and The Republic of Tea hasn't confirmed on the record that its seal is free of it. That unconfirmed melt seal is why this lands at minimal-contact rather than plastic-free - it's clearly better than a nylon/PET mesh pyramid, but not confirmed clean. Independent PFAS screening of a round bag came back non-detect for fluorine, which doesn't rule out a (non-fluorinated) melt seal. If the brand confirms no polypropylene or PLA in the paper, this upgrades to plastic-free.

What it's made of
| Part | Material | Food contact |
|---|---|---|
| filter bag unbleached round single-chamber tea paper; no glue, staple, string, or tag | Paper | Yes primary 🔥 |
| seam seal heat-crimped seam likely relies on a thermoplastic melt fiber (polypropylene or PLA) blended into the paper - unconfirmed by the brand, and the reason for the minimal-contact rating | Plastic other / unspecified | Yes incidental |
The Republic of Tea's format is unusual: a small round, flat bag with no string, tag, or staple, packed loose in a reusable tin rather than individual envelopes. It's designed to steep quickly and to minimize packaging waste.
Pros
- No string, tag, or staple - the lowest-waste bag format here
- Unbleached paper, confirmed no chlorine
- Loose in a reusable tin, so no individual plastic-lined envelopes
- Independent lab (Mamavation) found non-detect fluorine on the chamomile round bag
Cons
- The glue- and staple-free round seal likely uses a thermoplastic melt fiber the brand hasn't confirmed absent - the reason it isn't rated plastic-free
- Materials transparency stops short of the one detail that would settle the rating
