Plastic in Tea Bags (and all the brands that don’t contain it)

You’d probably be surprised to learn that most tea bags contain up to 25% plastic. In fact, we didn’t know about plastic in tea bags until we watched a viral BBC video about tea production in 2017.

Canadian researchers published a study in the American Chemical Society’s Journal of Environmental Science and Technology which found that steeping a single plastic tea bag at brewing temperature releases about 11.6 billion minuscule particles known as “microplastics” and 3.1 billion “nanoplastics” into each cup (source).

Plastic in Tea Bags & How to Avoid It

“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. A cup of tea contains thousands of times greater mass of plastic, at 16 micrograms per cup.”

A spot of tea… and some plastic?

When you look at a tea bag, plastic usually isn’t the first thing that comes to mind. Yet about a quarter of each tea bag (from most brands) is comprised of this substance. You can watch how tea bags made (see it here) to see how plastic is incorporated.


It may be hard to believe, but most brands of bagged tea contain plastic. With millions upon millions of cups consumed daily, this adds up to a lot of plastic.

So why is plastic in tea bags to begin with?

In order for the tea bags to seal up and keep their shape in hot liquid, a plastic polymer, namely polypropylene, must be added. Even though the amounts of plastic found in tea bags is minimal — and vary between manufacturers — it adds up to quite a bit when you look at the big picture.

Due to the plastic content, conventional tea bags cannot completely decompose. This makes them a bad option for compost material and the environment… not to mention your body!

Like most plastics, polypropylene is known to adversely affect the body’s endocrine system (source). And as we’ve covered many times, endocrine disruptors can lead to a plethora of health issues and other maladies that can become chronic conditions (source).

One would think making the switch to plastic-free tea bags would be easy, but many tea manufacturers protest that non-plastic bags would be too costly to implement.


The rich antioxidants (also called polyphenols) in green tea are extremely beneficial to the heart and brain. Tea is known to alleviate acne, bad breath, colds, stress, and prevent eye diseases like glaucoma. Although too much caffeinated tea can lead to a lack of sleep, just the right amount before bedtime is one of the many therapies that are recommended to put an end to raucous snores, leading to better overall sleep as well.

The University of Maryland Medical Center reports that, “Polyphenols contained in teas are classified as catechins. Green tea contains six primary catechin compounds: catechin, gallaogatechin, epicatechin, epigallocatechin, epicatechin gallate, and apigallocatechin gallate (also known as EGCG). EGCG is the most studied polyphenol component in green tea and the most active.”

“Green tea also contains alkaloids including caffeine, theobromine, and theophylline. They provide green tea’s stimulant effects. L-theanine, an amino acid compound found in green tea, has been studied for its calming effects on the nervous system.”


Although the bigger tea bag manufacturers seem hesitant to make the switch to plastic-free bags, you don’t have to wait to start drinking tea the safer and eco-friendly way.

You can also choose brands that don’t use bisphenol-A (BPA), phthalates, or polypropylene. Other great options are tea bags made from organic cotton, hemp, or certain plant fibers.


If you’ve used bagged tea because you thought loose leaf was too much trouble, you’re in for a pleasant surprise. Organic loose leaf tea can be made just as conveniently and it’s typically more flavorful because the tea leaves haven’t been ground to dust to fit into a tiny plastic-riddled tea bag!

Many organic loose leaf tea brands come in easy to store tins or eco-friendly packaging.

Loose leaf tea is a more economical choice since they are priced by weight while tea bags are priced per bag. You can also reuse loose leaf tea to make a second cup to cut expenses and waste. You can buy loose leaf tea in bulk. This involves as little waste and plastic contamination as possible, but loose leaf tea can also be purchased in cans or boxes if bulk is not an option for you.


There are plenty of simple ways to avoid plastic tea bags. One way that probably doesn’t require any new kitchen purchases on your part is to boil water on the stove top and pour it into a mug of loose leaf tea. If you don’t want to drink tea leaves, strain it with a stainless steel strainer or a piece of cheese cloth you can wash and reuse.

A stainless steel tea infuser eliminates plastic contamination and the need for straining. Pour hot water into a tea mug and steep with loose leaf tea in the infuser for 3 to 5 minutes.

This electric kettle makes heating water extremely fast and easy.

This glass tea kettle comes with a stainless steel infuser. We add filtered water, turn on the gas stove, and add two teaspoons of loose leaf tea to the infuser as the water is heating. The process takes about 7 minutes from start to simmering in your favorite mug.

For Keurig users – Instead of buying single-use pods (10 billion of them end up in landfills each year) to brew tea in your Keurig, get a stainless steel refillable pod to use again and again. Simply scoop about two teaspoons of loose leaf tea (or coffee) into the pod and use your Keurig as usual. One of the Green Child team members used the same stainless cup for 8 years and it’s still in perfect condition.


If you just really love brewing bagged tea, look for brands that don’t use plastic in their teabags. It’s hard to find a published list anywhere, but from the outreach we’ve done, here are some brands that have confirmed they do not use plastic in their string-and-tag teabags:

Numi Organic Tea – “We’ve been concerned about the potential health risks of steeping chemicals in hot water since day one. We use biodegradable, unbleached Manila hemp fiber for our tea bags. They are Non-GMO verified and will degrade over time in a normal compost heap.” – Ahmed Rahim, CEO and co-founder of Numi Organic Tea.

Republic of Tea – “Teabags from The Republic of Tea come in our signature unbleached round paper teabags with no unnecessary strings, tags, or staples – the same way we have been making great tasting tea bags for over 27 years.  The Republic of Tea does not make nylon or silken tea bags.”

Clipper Tea – They announced on their website in 2018, “We are so proud to have launched the world’s first plastic-free, unbleached and non-GM pillow tea bags.”

Pukka Herb teas – Their website states: “We use a simple stitch of organic cotton and a unique folding process. This means we don’t need to use polypropylene to hold our teabags together and our teabags are free from plastic. We were the first company to ever use organic strings to hold our teabags together without the need of a metal staple or polypropylene.”

Yorkshire Tea – This is a new addition! As of September 2021 Yorkshire has transitioned away from plastic. There still could be some of the old plastic bags on shelves, so here’s how to tell which packaging contains the new bags.

Tielka – In 2017, Tielka started packaging their Fair Trade teas in a plant-based tea bag fabric that comes from a sustainable, bio-renewable source. Tielka tea bags are also industrially compostable.

  1. Paper tea bags are useful at work, because my office doesn’t have a compost bucket., Do you know if paper tea bags meant for loose-leaf tea also have micro-plastics? I have seen T-Sac paper tea bags at shops near me. They say that their product is compostable. But I don’t know if there are regulations about what “compostable” means on product information.

  2. good. but must be mindful of your kettle type as well as the bags. electric kettles have microplastics too.

  3. I had no idea plastic was used to make tea bags! I drink teas from Yogi and Traditional Medicinals and checked to see if they use plastic in their teabags and I’m happy to report they do not. Both websites contain a lot of information regarding their packaging. While mostly a coffee drinker and only occasionally a tea drinker I will consider loose tea in the future. Thank you for this article!

    Hi Amity,

    I am the founder of PilKi and we offer Labrador Tea infusions. We offer loose tea leaves and won multiples awards in Canada. We’d love to be included in this list. Our website is and you can find information on our ecoresponsible efforts –

    Thank you so much! ?

  5. K McGregor says:

    What a rude awakening article and not in the bad sense! I had no idea polypropolene was used in tea bags! Had I known this years ago, I would have changed to loose leaf teas. I’ve since switched to Ohn Market’s loose teas and biodegradable tea bags.

  6. Lisa Song says:

    Hi Amity,

    I am Lisa the founder of Golden Wattle Australian tea . I have been in tea business for over 10 years and I am sincerely worried about the damage of tea bag to the environment as well as to our health. Thats why I started my tea brand with only loose leave tea and tried my best to resist the temptation of using tea bag as I believe we shouldn’t compromise our planet and our health just for some convenience. I would love to invite you to try our tea if possible.

    1. Amity Hook-Sopko says:

      Thanks for putting Golden Wattle Tea on our radar, Lisa!

  7. I believe Yorkshire Tea now manufacture their teabags with zero plastic. I had reason to write to them because I had bought a batch, some of which were splitting. They replied and apologised, explained that they were in the process of making the switch to ‘non-plastic’ and sent me two large boxes of the new bags to compensate.

    1. Amity Hook-Sopko says:

      Thanks so much for commenting, Stuart. We’ve just updated the article with their statement. This is really helpful!

      1. Rebecca Domorev says:

        Thankyou so much! 🙂

        1. Amity Hook-Sopko says:

          Thanks for letting us know, Rebecca. Your packaging is beautiful, by the way! We’ve just made the update. Keep up the great work 🙂

  8. My question to the editor of this article:
    Can you still use the bagged tea by removing the leaves to transfer them to a steel or alternate infuser to make tea?
    Suggestions please for those who want to transfer from polytherene teabags.

    1. Amity Hook-Sopko says:

      Yes, I’ve done this with tea we’ve been gifted or after helping my mom transition out of her old brands. It’s a great way to keep from wasting tea. A slight downside is that the tea leaves have usually been ground up really small, so you may end up with a little more residue in the bottom of your mug.

  9. Lynn Carmichael (Ms.) says:

    No, there is no transparency, no pun intended, and no full disclosure, even at this late date, regarding the materials and compounds used in teabags, on the packaging. I give Red Rose credit for disclosing to you, but what a shock! If it’s too toxic for a compost heap, those teabags shouldn’t be infused in very hot water and the contents consumed!
    Tea consumption is finally coming under way overdue scrutiny; after all, it’s the second-most consumed beverage in the world!

  10. I’ve used plenty of tea bags and I’ve never had any trouble with them. I want to start making my own tea and tea bags but I thought about sealing them off my sewing the sides shut with needle and thread. Would using store bout tea bags really be harmful to the body? wouldnt it take years for the effects to finally start presenting themselves?

  11. Hi Nan, This is months after your post but I found out years ago Red Rose Tea bags are made with polypropylene. I had contacted them to see if they made tea bags without staples (they staple string to tea bag for dipping) so I could drop them in my compost pile w/o having to remove the staples. Customer service responded to me that I shouldn’t use their tea bags for compost because they contained polypropylene. I’ve since switched to fresh tea and a metal tea infuser. I’m sure you’ve talked to Red Rose by now but wanted to add my comment just in case. Unfortunately, the bag’s materials weren’t published on the box at the time, maybe they are now.

    1. It’s years later, but I wanted to give an update. I just emailed Red Rose and received this response, “Thank you for taking the time to contact us here at Red Rose. Please be advised that the tea bags are made from a natural abaca fiber which is a natural alternative to using plastic material. Red Rose teabags do not contain plastics in the teabag material.”

      1. Ty so much for clearing this up ty indeed

    2. Thank you for the useful update on which brands to use. When the issue first came to light, I decided to move back into loose or home grown teas as much as possible but it’s not always easy to find this during the weekly shop. I don’t think the suppliers or retailers have really taken on board the public health issues either as the same few companies are now busy launching coffee bags with non biodegradable plastics in many cases. Another one to watch out for.
