Are Microplastics in Tea Bags Putting Your Health at Risk?
As a virtual assistant who runs on multiple cups of tea a day, I’ve always been mindful of what goes into my brew. Years ago, I learned that traditional bleached tea bags can release harmful chemicals into your tea.
That’s when I made the switch to Clipper Tea, drawn by their promise of unbleached and eco-friendly bags. However, even Clipper uses PLA—a plant-based plastic—to seal their tea bags, and recent studies have shown that PLA can still release microplastics under high heat.
This discovery has sent me searching for even better options. If you, like me, want to enjoy your tea without worrying about microplastics, read on for some healthier, eco-friendly alternatives.
What Are Microplastics and Why Should We Care?
Microplastics are tiny particles that result from the breakdown of larger plastics or are intentionally added to products. Research has revealed that steeping tea bags in hot water can release these particles into your cup.
A recent study published in Environmental Science & Technology found that premium plastic tea bags release billions of microplastic particles into tea when brewed at typical steeping temperatures. Over time, these particles may pose health risks, although their full effects are still being studied (source).
Similarly, a study from the Autonomous University of Barcelona highlights the broader issue of microplastics in food and beverages. It emphasises the potential for microplastics to be absorbed by human cells and the need for regulation to mitigate exposure (source).
The Problem With Tea Bags
Many tea bags, even those marketed as organic and "eco-friendly," use materials like polypropylene or PLA to seal the bag. While PLA is plant-based and biodegradable, it can still release microplastics when exposed to high temperatures, as shown in these studies.
This means that even if you’ve opted for sustainable brands, you might still be unknowingly consuming microplastics. But don’t worry—there are simple solutions.
How to Enjoy Tea Without Microplastics
Here are some ways to enjoy your tea while avoiding the risks:
1. Choose Plastic-Free Tea Bags
Some brands have taken steps to eliminate plastics entirely:
Pukka Teas: Their tea bags are stitched with organic cotton and contain no glue or plastic.
Hampstead Tea: Uses unbleached, biodegradable paper tea bags with no plastics or PLA.
Numi Organic Tea: Their tea bags are made from biodegradable, unbleached Manila hemp fiber and are completely compostable.
2. Switch to Loose-Leaf Tea
Loose-leaf tea eliminates the need for tea bags altogether and offers a fresher flavour. Here are some ways to brew it:
A teapot with a built-in strainer for larger batches.
An in-cup stainless steel tea infuser for single servings.

4. Experiment With Accessories

Disposable fillable tea bags: Made from biodegradable materials, these are perfect for enjoying loose-leaf tea with the convenience of a traditional tea bag.
Glass or ceramic tea or stainless steel infusers: Stylish, plastic-free options for brewing your tea.
Cast Iron Teapots: A fantastic option for brewing loose-leaf tea, cast iron teapots not only enhance the flavour of your tea but are also incredibly durable. For example, Japanese cast iron tea pots are not only beautifully crafted but also induction hob friendly, making them a versatile choice for any kitchen.
