A review of 19 studies finds that plastic particles can enter tea via packaging and brewing, with teabags identified as a major source of microplastics in hot drinks; counts vary by bag type and lab method, with some bags releasing billions of particles, while the health implications remain unclear and more research is needed.
A review in Food Chemistry finds teabags—often made with plastic mesh or mixed materials—are a leading source of microplastics and nanoplastics in tea. When exposed to boiling water, some bags can release more than a billion particles into the brew, with studies reporting up to 14.7 billion particles per bag depending on methods and detection. Results vary due to testing techniques and contamination risks, and researchers also note possible leaching of plastic additives, though health implications for humans remain unproven. The takeaway is that familiar tea packaging can be a major source of plastic contamination in tea, though exact quantities are not uniform across brands or studies.
