Tazo's standard rectangular filterbags are paper heat-sealed with polypropylene. Hernandez et al. 2019 (Environ. Sci. Technol., McGill) measured ~11.6 billion microplastic and ~3.1 billion nanoplastic particles released per cup from plastic-containing tea bags brewed at 95 °C. Banaei et al. 2024 (Chemosphere, UAB Barcelona) confirmed polypropylene bags shed ~1.2 billion particles per mL and demonstrated particle uptake by human intestinal cells in vitro. There is no established safe exposure threshold for chronic ingestion of polypropylene nanoplastics from food contact materials.
