Is there plastic in your tea bags

Is There Plastic In Your Tea?

Is there anything better than a nice cup of tea?  Even the very word itself is soothing and comforting – like a hug when you need one most.  A steaming hot mug of tea is the first thing I reach for in the morning, and quite often a herbal tea is one of the things I reach for last thing at night.  I measure my days based on my tea consumption – a good day if I’ve had plenty cups, and a bad day if tea has been in scarce supply.  In short, there are few things I love more than tea.

What is your beloved cup of tea is hiding a dark secret?  Well, I’m afraid to be the harbinger of doom, but much like the animal fat in £5 notes scandal, there is a bad side to your benign cup of tea, and that is plastic.  Not just the plastic wrapper on the box, or the plastic pouch some teas come in, but plastic actually in the teabag itself.

Let that sink in a moment – there is plastic in the teabag.

You might be wondering why there is a need for plastic to be found in teabags?  Well, plastic (polypropylene to be exact) is apparently added to the paper teabag to help heat seal them during manufacture so they don’t come open in the box, or in your cup.  It also means though that these tea bags aren’t 100% biodegradable, which is a bit of problem.

As a lot of the information stems from 2010, I wanted to get an up-to-date overview of the tea industry in 2017.   I donned my investigative cap and emailed a few tea makers to see if they could confirm whether they still use polypropylene in their teabags and to see which tea bags are plastic free.  Here’s what they said:

plastic in tea bags

Teapigs got back to me first (within minutes) to let me know that all of their teabags are made from a by-product of corn starch known as Soilon.  The box that they are sold in does appear to contain some plastic though, so if that is an issue then this may not be your solution.

Taylors of Harrogate (who also make Yorkshire Tea and Betty’s Tea) say that “we can confirm that we are working with our supplier of teabag paper to develop a paper that is 100% plant-based, but right now our tea bags do contain polypropylene as part of the fibres“.

Twinings have several different types of teabags available on the market.  They say that “our standard teabags, used for Earl Grey and English Breakfast, to name a couple, and many of our infusions and Green teas are produced from a natural plant based cellulose material and contain no plastic in the fibres. However, these teabags are “heat sealed” tea bags, and so the paper also has a very thin film of polypropylene, a plastic, which enables the two layers of the tea bags to be sealed together“.

Meanwhile their ‘string and tag with sachet’ tea bags, also contain a thin layer of plastic polyethylene to help seal up the sachets.  The only Twinings product that doesn’t contain any plastic is their pyramid teabag range – whereby the material is derived from maize starch and is fully biodegradable and compostable.  Rather annoyingly though, many of their pyramid tea bags seem to come in plastic bags rather than boxes.

Pukka Tea told me their teabags do not contain polypropylene or any other plastic – their teabag is sewn shut by machine with cotton thread.  They even went on to say their teabag paper is made of a blend of natural abaca (a type of banana) and plant cellulose fibres, and their supply of tea bag paper is also Totally Chlorine Free and unbleached.  They are staple-free and 100% biodegradable and/or recyclable. The tea bag strings are made from 100% organic, non-GMO, un-bleached cotton.  Each teabag is individually packaged though (possibly in plastic), so the one downside is that there is a bit of waste from one box of tea .

PG Tips say their “teabags are made with 80% paper fibre which is fully compostable along with the tea leaves contained in the bag.  The remaining packaging includes a small amount of plastic which is not fully biodegradable: this is needed to create a seal to keep the tea leaves inside the bag“.  However, they didn’t have the information to state whether or not this was polypropylene.

Tetley also say their round and square teabags are made with 80% paper fibre, and 20% thermoplastic.  Their string & tag teabags are plastic free- but are used mostly in their catering range for individually wrapped tea bags.  They have said that “Tata Global Beverages has ongoing continuous improvement and environmental awareness.  We are working towards more sustainable and biodegradable solutions for all our products”.  They also advised that ripping ripping the bag and dispersing the contents should help the composting process.

Typhoo, and Clipper have so far declined to comment.  I’ll update as and when they do.

So whilst Teapigs, Pukka Tea, Twinings Pyramid tea bags and Tetley’s catering range are plastic free, in pretty much all cases the packaging is not.  The teas are also on the more expensive side.  I find these types of tea are nice for a treat, but may be a little pricey to enjoy as your everyday cup of tea.  Especially if you have a prolific tea habit.

If you are keen to enjoy your tea without the added plastic the other option is to switch to loose leaf tea.  I’ve been hunting down some handy accessories that might come in handy if you choose to do so:

Plastic Free Tea Alternatives

Reusable Tea Bags (£7.98 for 5) (or make your own)

Tea Ball Infuser (£3.25)

A pretty fairtrade mug (£9.95)

A cheery teapot (£24.95) with infuser basket so no need for additional tools or tea leaves floating in your tea.

What’s your favourite loose leaf tea?  Is there a 100% plastic free loose leaf tea?  I’ve found some sold in a paper bag but it does have a sticky label on it which I suspect isn’t plastic free.  I’d be keen to hear your finds!



  1. Interesting… I use Pukka a lot, and always buy Clipper for normal tea (because they do organic) and rooibos. Will be checking back to see what they say!

    • They have replied to me on Twitter and said that “Currently, the filter paper in our pillow tea bags does contain polypropylene to provide the heat-seal function. Most standard square or round tea bags in the UK contain the same. We hope this helps!”.

  2. Great article. I’ve switched to loose tea and would be interested to hear any recommendations for places that sell in bulk (where you bring your own container) – particularly in East London!

  3. I drink Dorset tea and asked them the same question a couple of months ago and they sent me the following reply-
    “Thank you for your email and your interest in Dorset Tea. Below is a response prepared by our Quality department regarding the material used for our teabags:

    “The standard heat-sealable paper comprises of approximately 75% cellulose fibres, 25% synthetic fibres for the heat-sealing properties and 1% wet-strength resin. The cellulose fibres used in the manufacture of the teabag paper are a blend of unbleached non-wood fibre e.g. abaca (i.e. which is part of the banana family) and wood pulp. The wet-strength resin which, as the name implies, is in the composition to ensure the teabags retain their integrity in boiling water – the use of which is permitted in food contact regulations. If you include the tea inside the tea bag, 99% of the teabag is compostable.”

    Once composted, the remaining plastic/fibres can then be dispersed in the soil or can be picked out and disposed of.

    I hope this information has been helpful.

    Happy tea drinking”

    • Thanks for sharing that Debbie – that’s good of them to give you such a detailed response! I must admit I haven’t heard of Dorset tea before but I must look them up.

  4. Oh my goodness I had no idea! Thank you so much for this post and the information you have gathered. This is definitely the shove I need to go back to loose leaf tea :)
