A news report about plastic particles leaching from tea sachets and into teacups has been spreading online and through news publications across Canada, England, and the United States since the end of September when a research study from Montreal’s McGill University was published. The small scale study showed plastic teabags released as much as 60 millionths of a gram of plastic into a cup of tea.

Be sure that your tea sachets are made with biodegradable fabric.

News outlets seized upon the headline “You may be swallowing billions of tiny plastic particles while sipping a cup of freshly brewed gourmet tea.”

One news blog went on to say “The bags, which have been around since at least 2006, are sometimes called “silken” sachets. They can be made from hemp, corn-based plastics, nylon or polyethylene terephthalate. But most often it’s one of the latter two: plastics.”

That final sentence is not true.


The trend is entirely in the opposite direction. Industry-wide, the priority has been to move to fully biodegradable tea bags – even though this material is five times more costly than nylon or plastic. 

The only companies still using the outdated nylon fabric are a few supermarket brands who would lose their minuscule profit margins if they had to switch to more expensive biodegradable materials.


This tempest in a teacup is irrelevant for Elmwood Inn Fine Teas customers because we have never used plastic or nylon fabric for our tea sachets.

We avoided the first nylon machines – which appeared in the US twenty years ago – and moved directly from paper tea bags to pyramid sachets using plant-based (non-GMO cornstarch) material in 2011.
