Plastic Free Tea Bags: 5 Solutions Tea Providers Are Using

How do you like your tea? With cream? Sugar? Or the classic, plastic. That’s right, environmentally detrimental glue and plastic. Allow me to spill the tea.

Tea lovers sing many a praise of those green leaves which are rich in antioxidants and lowers heart failure risk. But little do they know that the tea bags we all use shed tiny pieces of plastic (microplastic) in our hot seemingly comforting cups of tea.

Most teabags contain up to 25% plastic. A study conducted by Canadian researchers revealed that a plastic tea bag at brewing temperature (95°C) releases around 11.6 billion microplastics in one cup. That is a lot of plastic!

Microplastics are shockingly also found in our food and water. A study suggests that we ingest a credit card’s worth of plastic each month. While that is worrisome, what’s more frightening is that the above-mentioned teacup contains more microplastic than our apparent usual intake.

What can we do about it? 

Well, we as tea drinkers can avoid tea bags for starters and buy loose tea with tea infusers (which you can easily find online).

But if you’re a tea bag person like me, you don’t have much to worry about. There are a few alternatives to plastic tea bags, which we have listed below along with the companies that use them and the properties their products retain.

Solutions Companies are using for Plastic Free Tea Bags


Cornstarch was discovered in 1840 by Thomas Kingsford who was a superintendent of a wheat starch factory in New Jersey.

It is a starch that is obtained from the corn grain.

Initially, it was used for starching laundry and other industrial uses but now it’s widely being used as a thickening agent, for medical purposes, manufacturing bioplastics, and for packaging applications, especially in food packaging.

Not only is it available in abundance but is also very affordable, contrary to Synthetic polymer materials which are produced from petroleum. This means hiked prices of petroleum result in hiked prices of the polymer. Not to mention that petroleum is an exhaustible resource.

Biodegradability: There’s some debate about the biodegradability of cornstarch. Some claim that it is a biodegradable material as if disposed correctly, under certain circumstances cornstarch will break into carbon dioxide and water eventually. The circumstances being the presence of enzymes like Proteinase K, which can catalyze the hydrolytic decomposition of cornstarch. But, if not disposed correctly, cornstarch may take years to decompose especially if no light or oxygen is available. However for this very reason, many believe that cornstarch is degradable and not biodegradable since Proteinase K is rarely available in nature.

Companies that are using Cornstarch  

1. Teapigs  

teapigs plastic free tea bags

Teapigs is one of the companies that have been using cornstarch for manufacturing their pyramid shaped tea bags which they refer to as “tea temples”. Their biodegradability isn’t limited to the cornstarch-based temples. The string that attaches temples to tag is also made of cornstarch. The tag is made of paper and the ink used on the label is vegetable-based, making the product fully biodegradable.

They finally seal the deal, and everything else with heat, which means no glue.

And the inner plastic-like bag is not plastic but is a wonderful material called NatureFlex made by Futamura by converting renewable air pulp into airtight packaging.

In May 2018, Teapigs became the FIRST tea brand to be awarded the Plastic Free Trust Mark – for plastic-free packaging. 


2. Abel and Cole 

Able & Cole plastic free tea bags

Abel and Cole produce tea bags among other organic products. They boast completely plastic-free tea bags and packaging. Their tea bags are made from Soilon a bioplastic made from lactic fermentation of glucose derived from cornstarch.

It is completely biodegradable and only takes a month to degrade. The packing in which the tea bags come in is made from paper which is biodegradable. To add to the list, they are glue-free as they use heat for sealing their products.

The material is also certified by The Soil Association through EU organic regulation.


3. Ahlstrom-Munksjö  

In July 2018, the Finland-based company announced an investment of EUR 28 million for biodegradable and compostable solutions to attract tea and coffee markets.

Ahlstrom-Munksjö has developed a technology called Fiber+ using polylactic acid (PLA), a renewable biopolymer, for their teabags. They used the same material in BioWeb® which they called the tea industry’s first spun-bond web.

BioWeb® filter’s unique non-woven web is visually different to wet-laid products. They also claim that the filter gets the most natural taste out of the tea bags.

It’s based on 100% renewable raw materials and is certified by DIN CERTCO.



Abaca which is also known as Manila hemp is extracted from Banana Leaves and is native to the Philippines and humid tropical areas. Because of its exceptional tensile strength, it is used by the paper industry for tea bags, banknotes, and decorative papers. It can also be used to make handcrafts like bags, carpets, and clothing.

As per the 2014 report, the Philippines is the world’s largest provider of Abaca fiber with a share of 87.4%. The rest of the shares were provided by Ecuador and Costa Rica with 12.5% and 0.1% respectively.

Biodegradability: In an experiment, water was poured on a sample of abaca fabric to test its biodegradability in which it started degrading after 2 months. The reason behind hemp’s high tensile strength is that it largely consists of silica (sand). This results in a tough yet biodegradable material.

Companies that are using Abaca

1. Clipper

Clipper takes pride in producing unbleached and plastic-free tea bags. Their tea bags are made of abaca with some plant cellulose fibers generated using unbleached and non-genetically modified papers which the company claims to be the world’s first.

For sealing they opt for heat instead of glue. Their outer packaging also consists of plant-based materials. You can throw the tea bags along with the packaging with food waste or compost.

In 2018, after many trials, the company was able to shift all the production over to the new paper.


2. Pukka

Pukka Herbs uses a simple yet efficient way of packing their tea bags. They use abaca for their tea bags which they simply stitch with threads of organic cotton (non-bleached) instead of staple pin and the company considered the world’s first to do so. In an effort to make sustainable packaging they print their products with vegetable ink. 


Wood Pulp

Wood Pulp — also known as cellulose fiber — as the name suggests is made from wood or bark of trees to be precise. Wood pulp paper is popularly used as filter paper for tea bags as they share similar properties with engineered fibers, which is why they are also used as chemical filter paper.

Cellulose is also widely used in the textile industry as fiber-reinforcement composites.

Being fully organic, cellulose completely degrades in soil and hence falls under the bio-plastic category.

Cellulose has the upper hand compared to other engineered fibers as it is low in cost and low in density which makes it affordable and easy to transport and carry.

Two Leaves endorses a special Paisley collection in which the tea bags are made from wood pulp. It can be made from multiple types of wood like spruce, pine, fir, aspen, birch, etc. They also claim that their bags are chlorine-free and that they avoid the use of staples for sealing their tea bags. 

Half of their teas are wrapped in envelopes that are certified compostable, the other half use a material designed to decompose.

Apart from helping the environment, the wood pulp adds to the taste as the fiber possesses excellent infusion. 


Cotton Tea Bag

A very popular alternative for sustainable and biodegradable is cotton tea bags. Cotton itself is a very popular material having innumerous advantages. It’s the perfect mix of softness, strength, and flexibility with biodegradability being cherry on top.

Cotton also gives race to its competitors in the field of renewability. Being around for centuries guarantees honed farming practices, perfected over the years.

Other Solutions to Plastic Tea Bags

US7905985B2 – Glatfelter

Problem stated– When filter bags dispose of a compost heap or a biowaste bin, depending on some parameters such as temperature, moisture, microorganisms, etc., the natural fiber component of the filter bag will get disintegrated and become biodegraded, whereas the thermoplastic polymeric fibrous network remains intact. Further, it’s impractical to separate the natural fiber component from the thermoplastic polymeric component.

Solution – The patent discusses that by adding specific lubricants, an amount of 0.5% to 5% weight of the ready filter, the aforementioned problem can be overcome. Specifically, they are aliphatic or partly aromatic polyesters.

EP3067455A1 – Nonwoven Network LLC

Problem stated– With the significantly improved fabrics, there still exists a need to increase the elongation of non-woven fabrics to enhance moldability. Also, there is a need to reduce overall costs by avoiding the process of making low melt fibers.

Solution – The patent discloses a non-woven web for producing pouches and bags with Polylactic Acid (PLA) fibers for creating a non-woven web through dry thermo-bonding. The PLA fibers have a crystalline portion and an amorphous PLA powder is added to PLA fibers to act as an adhesive for binding the PLA fibers together. Thus cost is saved by not needing the PLA amorphous to be extruded into a fiber but act as an adhesive.

KR101233310 – Daesang

Problem stated – The process of making tea bag ash is too long and if there is a faster solution, it makes the tea taste bitter or less convenient to drink. So, the patent solves the problem of making tea bags and to make it capable of rapid extraction and eco-friendly as well.

Solution – In the patent, it discusses the ingredient and the amount of the ingredients to make tea bags compositions which would be extracted rapidly and have the properties of eco-friendly at the same time.


As sustainability is the key goal of many industries, companies are opting for more eco-friendly solutions than endangering the environment.

Many tea trading companies have also shifted their production to plastic-free solutions but there are many companies around the globe who are trying to shift or thinking to shift their production. But as there are many alternates of plastic, they might face a dilemma to choose the best solution which would work for them?

To solve the problem to some extent we have provided the SWOT analysis of one of the major alternatives which can help a company to choose whether an alternate plastic solution works best for them or not.
