The last thing you want to think about while you're savoring your favorite tea is that you're ingesting microplastics. Unfortunately, plastic teabags are one of the biggest sources of microplastics. A study from 2019 found that steeping at brewing temperatures may do just that.
You might be wondering why there is a need for plastic to be found in teabags? Well, plastic (polypropylene to be exact) is added to the paper teabag at times to help heat seal them during manufacture. Most teabags are made from paper, with a small amount of plastic used to seal them shut. Some premium brands have switched to using greater amounts of plastic mesh for their products.
“We think that it is a lot when compared to other foods that contain microplastics,” Nathalie Tufenkji of McGill University in Quebec, told The New Scientist. “Table salt, which has a relatively high microplastic content, has been reported to contain approximately 0.005 micrograms plastic per gram salt." - Snippet from an article from Green Child Magazine
There are currently no proven health risks associated with drinking microplastics, but they take hundreds of years to break down. One way to avert this is choosing plastic-free tea bags is one solution, or better still, buying loose leaf tea and the use a strainer. We ensure that are brand aims to use 100% eco friendly bags but let us know your thoughts, would you like us to transition fully into loose leaf teas?
