Tea bags are often thought of as being made of paper. However, most tea bags contain plastic, with a recent study showing that one plastic tea bag can shed up to one billion microplastic particles into a single drink. Plastic tea bags pose a health risk, as well as contributing to plastic pollution. Due to the health and environmental dangers of plastic tea bags, many tea companies are moving towards plastic-free tea bags.

Plastic tea bags can shed billions of microplastic particles into your drink
The use of plastic in tea bags is concerning due to the potential health risks associated with consuming microplastics. These tiny plastic particles can accumulate in human fatty tissues and have been linked to various health conditions, including endocrine disruption, reproductive toxicity, cancer risk, problems with metabolism and nutrition, and interference with neurodevelopment. The European Union has classified more than 20% of plastic compounds as being of concern due to these potential negative consequences.
The problem is exacerbated by the fact that tea bags are subjected to high temperatures during the brewing process, which can cause chemical alterations in the plastic. Even 'food-grade' plastics can break down or release harmful materials when heated above 40°C. As a result, people who drink tea frequently made with plastic tea bags are continuously dosing themselves with billions of plastic particles, which may have unknown impacts on their health.
To avoid consuming microplastics from tea bags, individuals can switch to loose-leaf tea and use a stainless steel tea infuser or look for biodegradable tea brands. Some popular tea brands in the UK, such as PG Tips and Yorkshire, are also working on eliminating plastic from their tea bags. By making these simple changes, consumers can reduce their exposure to microplastics and potential health risks associated with them.
Additionally, disposing of tea bags containing plastic contributes to the plastic pollution problem. While tea bags may seem compostable, those containing plastic should be put in the trash to prevent introducing plastic chemicals back into the food chain. The best solution is to buy tea in bulk and use a metal strainer, or to cut open tea bags and compost only the tea leaves.

Paper tea bags often contain plastic fibres used in the sealant
Plastic in tea bags is a major issue due to its potential health risks and negative impacts on the environment. Paper tea bags often contain plastic fibres used in the sealant. These plastic fibres are added to the paper tea bags to prevent the paper fibres from coming apart when dipped in liquid.
One source states that even paper tea bags have an unsettling substance called epichlorohydrin added to them to keep them from bursting. Another source mentions that the plastic used to seal the tea bags is often invisible to the naked eye, making it impossible to discern whether a tea bag is truly plastic-free by sight alone. This is concerning because, despite being considered safer than some other plastics, plastic should never be heated. When plastic is heated, it can mess with how the body regulates hormones, and the plastic particles can enter the human body, with unknown long-term consequences.
Some tea bags that are not made of paper are also made of plastic. For example, silky pyramid-shaped tea bags are often made of nylon, a form of plastic. Similarly, Twinings square tea bags have a layer of plastic mesh embedded in the paper.
To avoid plastic in tea bags, one can switch to loose-leaf tea and use a strainer or a tea ball infuser. Some tea brands, such as Yogi Tea and Bigelow Tea, do not contain microplastics. Republic of Tea and Numi Tea also offer plastic-free and compostable tea bags.

Plastic tea bags should not be composted as they will introduce chemicals back into the food chain
Composting plastic tea bags can have negative consequences. While it may seem like a good idea to compost tea bags, if they contain plastic, they should not be composted. By putting tea bags that contain plastic in the compost, small amounts of plastic are introduced into the soil. This means that plants will absorb these chemicals as they grow, introducing them back into the food chain. Instead of composting, these bags should be put in the trash. Alternatively, the tea leaves can be removed from the bag and composted separately, with the empty bag then being thrown away.
It is important to be aware of the potential health risks associated with microplastics in tea bags. The consumption of microplastics has been linked to various health conditions, including endocrine disruption, reproductive toxicity, cancer risk, problems with metabolism and nutrition, and interference with neurodevelopment. The use of microplastics in tea bags poses a significant health concern, and the potential impacts on future generations are unknown. Therefore, it is crucial to avoid consuming microplastics and to dispose of plastic tea bags properly to reduce their impact on the environment and human health.
Some popular tea brands in the UK, such as PG Tips and Yorkshire, are working to eliminate plastic from their tea bags. There are also some truly plastic-free tea bag options available, such as Higher Living's compostable, plastic-free tea bags made from unbleached paper and organic cotton. Loose leaf tea is another alternative, which can be brewed using a strainer or a tea ball infuser. By making conscious choices, individuals can reduce their consumption of microplastics and minimize the environmental and health impacts of plastic tea bags.

Plastic tea bags are of concern due to their persistence, accumulation in human fatty tissues, and/or toxicity
A study found that tea bags made with polypropylene released about 1.2 billion small pieces of plastic per milliliter of tea, while nylon-6 tea bags released 135 million pieces, and cellulose tea bags released 8.2 million nano-range plastic particles. These plastic particles can be ingested and may accumulate in the body over time.
The European Union has classified more than 20% of plastic compounds as being of concern due to their persistence and potential toxicity. The health consequences of ingesting microplastics are not yet fully understood, but studies on animals have shown potential links to intestinal oxidative and inflammatory imbalance, gut biome disruption, lower sperm quality, impaired learning and memory, and interference with reproductive hormones.
Additionally, the disposal of plastic tea bags contributes to plastic pollution. When composted, plastic tea bags can introduce chemicals back into the food chain as plants absorb them from the soil. The persistence of plastic in the environment further highlights the concerns associated with plastic tea bags.
To reduce exposure to microplastics from tea bags, individuals can opt for loose-leaf tea, use reusable tea infusers or strainers, or choose tea brands that offer plastic-free packaging. It is worth noting that even paper tea bags may contain plastic fibers or sealants, so consumers should carefully research the materials used by tea companies to make informed choices.

Some popular brands are working on eliminating plastic from their tea bags
Plastic tea bags release billions of microplastics and nanoplastics into a single cup. This has led to growing concerns about the health risks posed by ingesting microplastics from tea bags. In response, some popular tea brands are working towards eliminating plastic from their tea bags.
Lyons tea bags, for example, are now made from a blend of natural fibres, including abaca, cellulose fibres, and a small amount of plastic fibres. While the brand acknowledges that the amount of plastic used is minimal, constituting less than 5% of the tea bag paper, they are committed to sustainability and are constantly seeking ways to minimise their environmental impact.
Similarly, Tetley, a well-known tea brand, has expressed its goal of eliminating plastic content from its tea bags. Tetley's All-Rounder tagless tea bags are primarily made from cellulose fibres (plant matter) but still contain a small proportion of food-safe plastic for heat-sealing. The company has been actively working with global tissue suppliers to find a workable solution and is confident that a reliable alternative can be achieved.
Other brands that offer plastic-free tea bags include Pukka Herbs, which uses organic cotton stitching instead of staples or polypropylene, and Clipper, which has phased out polypropylene in favour of a more sustainable heat-sealing method. Good and Proper Tea provides tea bags made from Soilon, a plant-based material derived from corn starch, while Madama Flavour offers eco-friendly pyramid tea bags made from soil and Soilon, a biodegradable PLA corn-starch material.
While some brands are making efforts to reduce or eliminate plastic, it is important to note that truly plastic-free tea bags remain rare. Many companies are transitioning to polylactic acid (PLA)-based materials, which are derived from plant starch and are biodegradable. However, there are concerns that plant-based microplastics may still pose similar environmental and health risks as conventional plastics.
