There’s something incredibly comforting about a hot cup of tea.
For years, most of us have simply grabbed a tea bag, dropped it into a mug, poured over boiling water and never thought twice about what that little bag was actually made from.
But lately, I’ve become much more conscious about the everyday products I use — especially the things that come into contact with my food and drinks.
And tea bags were one of those things I had never really questioned.
That’s why I’ve started choosing organic loose-leaf tea brewed in a glass teapot with a reusable tea infuser whenever possible.
It tastes better, creates less waste and gives me much more control over exactly what is going into my cup.
What’s Actually in a Tea Bag?
You might assume a tea bag is simply made from paper.
Sometimes it is.
But modern tea bags come in many different forms, and some contain plastic or synthetic materials.
Certain heat-sealed paper tea bags have traditionally used small amounts of plastic polymers such as polypropylene to help seal the bag, while some of those beautiful silky or pyramid-style tea bags can be made partly or entirely from synthetic materials such as nylon or PET.
Not every tea bag contains plastic, and many companies are now moving toward plastic-free and compostable alternatives.
But unless you check the packaging or manufacturer’s website, it isn’t always obvious what you’re steeping in your cup.
And that matters to me.
What Happens When Plastic Tea Bags Meet Hot Water?
This is where things get particularly interesting.
Researchers have investigated whether plastic tea bags can release tiny plastic particles when they’re exposed to hot water.
One widely discussed 2019 study published in Environmental Science & Technology found that certain plastic tea bags released large numbers of micro- and nanosized plastic particles into water during steeping.
That doesn’t mean every tea bag does this.
It also doesn’t prove that drinking tea from these bags causes disease in humans. Research into the health effects of microplastics is still developing.
But personally, if I can easily reduce an unnecessary source of plastic coming into contact with my boiling water, I’d rather do that.
Especially when the alternative is so simple.
Why I Prefer Organic Loose-Leaf Tea
Going loose-leaf eliminates the tea bag altogether.
Instead of wondering what the bag, glue or heat-sealing material contains, you’re simply putting tea leaves into a stainless-steel or glass infuser and allowing them to steep directly in hot water.
I also love choosing certified organic tea.
Organic certification doesn’t magically make a food perfect, but certified organic farming restricts the use of many synthetic pesticides and fertilisers.
Tea is an interesting product because we don’t wash the leaves before making a cup. We literally steep those dried leaves in hot water and drink the infusion.
For me, that makes choosing good-quality tea worth the extra effort.
Loose-Leaf Tea Can Be Better Quality Too
There’s another reason I love loose-leaf tea that has nothing to do with plastic.
The tea itself can be beautiful.
Open a good loose-leaf tea and you can actually see the leaves, flowers, herbs and spices.
Many inexpensive tea bags contain very finely broken tea leaves, sometimes called fannings or dust. Smaller particles brew quickly, which is convenient, but they don’t always provide the same flavour and experience as larger whole or partially whole leaves.
With loose-leaf tea, the leaves have room to expand and circulate through the water.
The result can be a richer, fresher and more complex cup of tea.
And once you start making tea this way, it becomes its own little wellness ritual.
My Favourite Way to Make Tea
One of the easiest changes you can make is buying a glass teapot with a removable stainless-steel infuser.
Add your loose-leaf tea to the infuser, pour over the appropriate temperature water and allow it to steep.
Then simply remove the infuser.
No disposable bag.
No string.
No staple.
And, depending on your tea and infuser, no plastic touching your hot water.
You can also see the beautiful colour of the tea developing through the glass, which somehow makes the entire ritual feel a little more special.
My Favourite Loose-Leaf Teas for a Wellness Cupboard
If you’re starting your own little tea collection, you don’t need dozens of varieties.
A few beautiful organic teas can cover almost everything you need:
- Green tea for a fresh daytime cup and naturally occurring polyphenols.
- Peppermint tea for a refreshing caffeine-free option, especially after meals.
- Ginger tea for a warming, spicy brew.
- Chamomile tea for a calming evening ritual.
- Rooibos for a naturally caffeine-free, earthy-sweet alternative to black tea.
- Loose-leaf black tea when you want a stronger traditional morning cup.
Just remember that herbal teas aren’t automatically suitable for everyone. Some herbs can interact with medications or may not be appropriate during pregnancy or for certain health conditions. Buy tea infuser HERE
Is Every Grocery Store Tea Bag Bad?
No — and this is an important distinction.
I don’t believe we need to become frightened of every tea bag in the cupboard.
Some brands now make tea bags specifically without conventional plastic sealing materials, and materials vary enormously between manufacturers.
If you love tea bags because they’re convenient, look for brands that clearly state that their bags are plastic-free and check what the actual bag is made from rather than relying only on words like “natural” or “biodegradable.”
The goal isn’t perfection.
It’s simply becoming more aware of the everyday things we’re consuming.
Organic Doesn’t Automatically Mean Plastic-Free
This is another important point.
An organic tea can still potentially be packaged in a tea bag containing synthetic material.
“Organic” generally refers to how the agricultural ingredients were produced — it doesn’t automatically tell you what the tea bag or packaging is made from.
That’s one reason I find organic loose-leaf tea such a simple solution.
I can choose organic ingredients while avoiding the disposable tea bag completely.
The Added Bonus: Less Waste
Think about how many tea bags a regular tea drinker throws away.
One cup a day becomes 365 bags a year.
Two cups becomes more than 700.
A reusable stainless-steel tea infuser can be washed and reused again and again, while many spent loose tea leaves can go into your compost depending on what has been added to the blend.
It’s one tiny household swap that can reduce unnecessary packaging without making your life more complicated.
A Simple Heartcore Wellness Swap
I’m becoming increasingly interested in the small changes we can make at home rather than trying to overhaul our entire lives overnight.
And this is one of my favourites:
Instead of this:
Generic tea + disposable tea bag + unknown bag materials
Try this:
Organic loose-leaf tea + glass teapot + reusable stainless-steel infuser
It’s simple, beautiful and turns something you probably already do every day into a little wellness ritual.
The Bottom Line
Tea itself can be a wonderful addition to a healthy lifestyle.
The issue isn’t that every tea bag is “toxic” or that drinking an occasional supermarket tea is going to harm you.
It’s that some tea bags contain plastic or synthetic components, research has shown that certain plastic tea bags can release micro- and nanoplastic particles during brewing, and there are now incredibly easy ways to avoid them.
Choosing organic loose-leaf tea and brewing it in a glass teapot with a reusable stainless-steel infuser means you know much more about what’s going into your cup.
And honestly?
Once you’ve made a beautiful pot of loose-leaf tea and watched those leaves slowly unfold, going back to a dusty little tea bag just doesn’t feel quite the same.
