evidence: Would you like plastic with your tea? That sounds like a pretty straight forward question, but it’s also a bit of a trick question. Not all tea bags are created equal and for those people who are trying to go plastic-free, it may be time to re-evaluate what’s in your cup of tea. [...] Heat sealed bags, such as the round and square tag-less varieties, contain a small amount of plastic. The tea bag itself is often made with a natural fiber, however, natural fibers don’t melt and fuse together which is why the synthetic materials are added. These tea bags have a small amount of plastic thread that goes around the edge and then the heat seal melts the two sides of the tea bag together. These tea bags are not compostable. [...] The first question is which tea bags are plastic-free. When doing research for this post, I found a lot of information on British tea companies. Of course. What is more British than a cup of tea? But American tea manufacturers weren’t so upfront with posting what’s in their tea bags on their company website or answering my questions when I called them directly.
