Clipper Teas Tea Bags
Unbleached paper bag with an organic cotton string - but the heat-seal is PLA, a bioplastic marketed (contentiously) as "plastic-free."
The verdict: Minimal plastic contact
The bag paper is a blend of abaca and plant cellulose - but the mainstream "pillow" bag is heat-sealable because PLA is blended in as the sealing fibre. In 2018 Clipper swapped the oil-based polypropylene seal for PLA and called it "the world's first plastic-free tea bag." PLA is a plant-derived thermoplastic - still a plastic - so this sits at minimal-contact: mostly paper, with a bioplastic in the steep path rather than a starch or a fold-seal. It's materially better than a solid PLA or nylon pyramid, but the "plastic-free" framing is why independent commentators pushed back and why UK guidance nudged the industry to say "plant-based / biodegradable" instead.
Verification: Manufacturer confirmed
What it's made of
| Part | Material | Food contact |
|---|---|---|
| filter bag abaca + plant cellulose paper - unbleached | Paper | Yes primary 🔥 |
| heat-seal fibre PLA (plant-derived bioplastic) blended in to make the bag heat-sealable - the plastic in an otherwise paper bag | PLA polylactic acid, "bioplastic" | Yes incidental |
| string organic certified cotton (string-and-tag lines) | Cotton | No |
| tag | Paper | No |
Clipper is a UK organic and Fairtrade tea brand. Its standard bag is an unbleached paper "pillow" style; a separate string-and-tag line exists. Clipper has built much of its marketing around a "plastic-free" tea bag.
Pros
- Unbleached paper with an organic cotton string on the string-and-tag lines
- PLA is at least plant-derived and industrially compostable, unlike the polypropylene it replaced
Cons
- The heat-seal is PLA - a bioplastic, so the bag is not actually plastic-free despite the marketing
- PLA is industrially compostable only (not home or environmental) and still sheds micro/nanoplastics when steeped
- No independent PFAS/fluorine testing of Clipper bags was found
Notes
- Clipper's separate string-and-tag line reportedly uses a wood-cellulose binder without PLA and could rate higher - but that needs per-SKU confirmation; the common heat-seal bags are the PLA ones
