Picture this: it’s a chilly morning, and you’re curled up with your favorite mug of steaming hot tea. Ah, bliss, right? Well, maybe not entirely. You see, that comforting cup might be hiding a not-so-pleasant surprise: microplastics. Yep, you heard that right. Those tiny bits of plastic that are polluting our oceans and harming marine life could be lurking in your tea bag.
I know, it’s a bit of a bummer. We think of tea as this pure, natural drink, but the truth is, many tea bags contain plastic. And when you brew those tea bags, those microplastics can end up in your drink – and ultimately, in your body. Not exactly the kind of “flavor” you want in your morning routine, huh?
But don’t toss your tea kettle just yet! Let’s break down what microplastics are, how they’re sneaking into our tea, and what you can do about it.
Microplastics 101: Tiny Plastics, Big Problem
So, what exactly are microplastics? We have already discussed in very detail so please click here to find all about microplastics. Now the next question is :
How are they getting into our tea bags? Well, many tea bags are made with plastic. Some contain polypropylene, a type of plastic used to seal the tea bag and keep its shape. Others are made entirely of nylon or PET (polyethylene terephthalate), both types of plastic. When you brew these tea bags, these plastics can break down and release microplastics into your tea.
Microplastics in Tea Bags: Key Takeaways from the Research
Now, you might be thinking, “Okay, so there are some tiny bits of plastic in my tea. Is that really a big deal?” Well, the truth is, scientists are still learning about the long-term health effects of microplastics [sources]. But some studies suggest they could be linked to inflammation, hormone disruption, and even some types of cancer.
- Tea bags are a significant source of microplastics.
The study highlights that many tea bags, including those seemingly made of paper, contain plastic components like polypropylene (used for sealing) and nylon (used in pyramid-shaped bags).
- Hot water releases microplastics and nano-plastics.
When these tea bags are steeped in hot water, they release billions of microplastics and even smaller nano-plastics into your tea. One study found that a single plastic tea bag released approximately 11.6 billion microplastics and 3.1 billion nano-plastics into a single cup.
- The health consequences are still uncertain.
While the exact health effects of ingesting these microplastics are not fully understood, the research indicates potential risks like inflammation, hormone disruption, and even links to certain cancers. More research is needed to determine the long-term impacts.
- There are environmental concerns.
The plastic from tea bags contributes to plastic pollution, ending up in landfills and oceans, harming marine life and ecosystems.
- Loose leaf tea is a safer alternative.
The paper encourages switching to loose leaf tea to avoid microplastic consumption from tea bags.
Not All Tea Bags Are Created Equal: A Guide to Tea Bag Materials
You might think all tea bags are made of, well, paper. But it turns out, there’s a whole world of materials out there, and some are definitely better than others. Let’s break it down:
- Paper: Good old-fashioned paper tea bags seem like the safest bet, right? Not always. Many paper tea bags contain a hidden plastic: polypropylene. This plastic is often used to seal the tea bag and help it keep its shape. So, even if the bag looks like paper, it might still be leaching microplastics into your brew. Sneaky, huh?
- Nylon: Nylon tea bags are made from – you guessed it – nylon, a type of plastic. These are pretty common, especially for pyramid-shaped tea bags. Unfortunately, nylon tea bags are a major source of microplastics.
- PLA (Polylactic Acid): PLA is a plant-based plastic, often made from corn starch. It’s marketed as a more eco-friendly option, and it is compostable. However, PLA still breaks down into microplastics, so it’s not a perfect solution.
- Silk: Silk tea bags are a great plastic-free option. They’re made from natural fibers and are biodegradable. However, they can be a bit pricier.
So, which tea bags are truly plastic-free? Silk tea bags are your best bet. If you’re opting for paper, look for brands that specifically state their tea bags are plastic-free and made with unbleached paper.

Become a Tea Bag Detective: How to Spot the Plastic
Okay, so now you know the different types of tea bags. But how can you tell if a tea bag contains plastic when you’re standing in the grocery aisle? Here are a few detective tips:
- Shiny or Heat-Sealed?: If the tea bag has a shiny appearance or feels heat-sealed, it likely contains plastic.
- Check the Label: Look for phrases like “plastic-free,” “biodegradable,” or “compostable.” If the packaging doesn’t specify, it’s best to assume it contains plastic.
- When in Doubt, Ask: Don’t be afraid to reach out to tea companies directly and ask about their tea bag materials. Most companies are happy to provide this information.
By being a savvy shopper, you can avoid those pesky microplastics and enjoy a cleaner cup of tea.
Ditch the Plastic, Keep the Flavor: Alternatives to Traditional Tea Bags
Okay, so we know plastic tea bags are a no-go. But don’t worry, you don’t have to give up your tea ritual! There are plenty of ways to enjoy a delicious, plastic-free cup. Here are a few of my favorites:
- Loose Leaf Tea: This is the OG way to enjoy tea, and it’s making a major comeback. Loose leaf tea gives you the purest flavor and aroma, and it’s completely plastic-free. Plus, you can often find it in bulk, which reduces packaging waste. Win-win!
