Tielka plastic-free pyramid tea bags

Did you know that brewing a plastic tea bag at 95°C releases around 11.6 billion microplastics into a single cup? (source)

"Table salt has been reported to contain approximately 0.005 micrograms plastic per gram. A cup of tea contains thousands of times greater mass of plastic, at 16 micrograms per cup." — Nathalie Tufenkji, McGill University

16μg

of plastic per cup from a conventional tea bag — thousands of times more than table salt. That's not something we were willing to serve.

When we started packaging our award-winning organic teas in pyramid tea bags in 2017, we made a decision: plant-based fabric only, from a sustainable bio-renewable source, sealed by ultrasound rather than harmful glue.
