What’s the Tea? … The Problem is in the Packaging

The Hidden Chemicals in Tea Bags and How to Avoid Them: A Guide to Healthier Brews

When you sit down to enjoy a soothing cup of tea, the last thing you want to think about is whether harmful chemicals might be steeping alongside your drink. However, many tea bags sold in stores contain plastics and chemicals that can leach into your tea when exposed to hot water. These chemicals can pose long-term health risks, and understanding what's in your tea bag is the first step toward making healthier choices. In this post, we'll explore the plastics and chemicals commonly found in tea bags, their potential risks, and how you can avoid them by choosing safer store-bought options.

The Problem: Plastics and Chemicals in Tea Bags

Many commercial tea bags, especially the pyramid-shaped ones or those with a silky texture, contain plastic. Polypropylene, a type of plastic, is often used to seal the edges of tea bags and maintain their shape. When these plastic tea bags are steeped in hot water, microplastics can be released into your cup. While the exact health effects of ingesting microplastics are still being studied, it's a growing concern as these particles can accumulate in the body over time.

In addition to plastics, some tea bags are treated with chemical agents such as chlorine or epichlorohydrin (a chemical used in the production of epoxy resins). When exposed to water, epichlorohydrin can break down into a substance called 3-MCPD, which has been linked to cancer in animal studies. Although the levels of these chemicals in a single tea bag might be low, repeated exposure could have cumulative effects on your health.

How to Avoid Plastics and Chemicals in Your Tea

While it may be disheartening to learn that your favorite tea might be harboring hidden chemicals, the good news is that there are plenty of ways to avoid them. Here are some tips for selecting safer, store-bought teas:

1. Opt for Loose Leaf Tea

One of the best ways to avoid plastics and chemicals is to skip tea bags altogether and opt for loose-leaf tea. Loose leaf tea is typically free of the packaging that contains harmful substances, and it allows you to control the quality of the tea you're consuming. You can use a stainless steel or glass tea infuser to steep your loose tea leaves, ensuring a pure and clean brew.

2. Look for Unbleached, Organic Tea Bags

If you prefer the convenience of tea bags, look for brands that use unbleached, organic tea bags. Unbleached bags are free from the chlorine treatment that can leave behind harmful byproducts. Organic brands are also more likely to use natural fibers like hemp, cotton, or paper, which are biodegradable and free of plastic.

Brands like Traditional Medicinals, Numi, and Clipper Tea offer organic tea bags that are plastic-free and unbleached. These companies are transparent about their materials and prioritize sustainable, chemical-free production. You can also mix your own loose leafs and steep in a bag, or transfer your favorite brand to a safer bag.

3. Choose Plastic-Free Tea Bags

Some brands have recognized the demand for plastic-free options and have started producing tea bags made from plant-based materials like cornstarch or abaca fibers. These bags are completely biodegradable and free from synthetic plastics. Look for packaging that specifies “plastic-free” or “biodegradable” tea bags. Polypropylene, mentioned above, is often also used to seal the bag. Sealed tea bags require this “glue” which can be detrimental and disruptive to the human body in addition to the environment. Instead, opt for tie bags, or bags that are certified by the Soil Association such as Abel & Cole.

Pukka Herbs, Yogi Tea, Republic of Tea, and Tea Pigs are other examples of brands that have switched to plastic-free, plant-based tea bags. These bags are safe to steep without the risk of microplastic contamination.

4. Check for Certifications

Certifications can be a helpful guide when selecting teas that are free from harmful chemicals. Look for teas that are USDA Organic, Non-GMO Project Verified, Fair Trade certified or certified by the Soil Association. These certifications often indicate higher standards in terms of how the tea is grown, processed, and packaged.

5. Avoid “Silky” or Pyramid-Shaped Tea Bags

Pyramid-shaped or “silky” tea bags are often made from nylon or polyethylene terephthalate (PET), both of which are forms of plastic. These types of tea bags may be marketed as luxurious or premium, but they come with the risk of leaching microplastics into your tea. Stick to more traditional tea bags made from paper or opt for loose leaf tea to avoid this issue.

My favorite resources for quality sourced loose leaf herbs and blends shipped to home are Rebecca’s Apothecary in Boulder, CO, and Mountain Rose Herbs in Eugene OR.

Final Thoughts: Making the Switch to Healthier Tea

Avoiding plastics and chemicals in tea bags is an easy switch once you know what to look for. Whether you prefer the convenience of tea bags or enjoy the ritual of steeping loose leaf tea, there are plenty of store-bought options that prioritize health and sustainability. By choosing teas that are organic, plastic-free, and chemical-free, you can enjoy your cup of tea with peace of mind, knowing that you're not exposing yourself to harmful substances.

Remember to always read labels carefully, seek out certifications, and opt for brands that are transparent about their materials. Your daily tea ritual should be a time of comfort and relaxation, not a source of unnecessary health risks. By making informed choices, you can enjoy your tea in its purest and intended form—free from unwanted chemicals and plastics.
