At BOS, we believe every cup of tea should be a celebration of nature: pure, refreshing, and free from unwanted additives. Yet, in today’s world, even this simple pleasure can come with hidden surprises.

More and more people are looking for ways to reduce microplastics in everyday life. That includes asking an important question: what exactly are tea bags made from?

That’s why BOS tea bags are made using BioWeb heat-seal filter paper, a plant-based material that is 100% natural and industrially compostable, designed to keep your brew clean while reducing environmental impact.

Let’s unpack why this matters.

Microplastics: The Tiny Invaders

Microplastics are minuscule plastic particles, less than five millimetres in size, that have infiltrated our environment, from the deepest oceans to the highest mountains.

They can be found in the air we breathe, the water we drink, and even in some of the foods and beverages we consume. Recent research has detected microplastics in human organs, including the brain, raising questions about their potential long-term health impact.

While tea itself is widely celebrated for its health benefits, the materials used to package it can sometimes undermine that intention.

Tea Bags: A Hidden Source of Microplastics

Not all tea bags are created equal.

Many conventional tea bags use synthetic sealing agents such as polypropylene, a petroleum-based plastic polymer that helps hold the bag together. When exposed to hot water, these materials can release tiny plastic particles into the drink.

Some studies have even suggested that certain tea bags can shed billions of microplastic particles into a single cup.

For consumers who are trying to live more consciously, this raises an obvious question: what alternatives exist?

What Makes BOS Tea Bags Natural and Compostable

At BOS, we’ve chosen a different approach.

Our tea bags are made from BioWeb heat-seal filter paper, which uses PLA (polylactic acid), a plant-based biopolymer derived from renewable materials such as corn starch.

This material allows the tea bag to seal effectively without relying on conventional plastics.

The result is a tea bag that is:

• Made from 100% natural materials
• Plant-based and derived from renewable resources
• Industrially compostable
• Designed to keep your tea experience clean and uncompromised

In industrial composting environments, these tea bags break down responsibly, helping reduce long-term environmental impact while maintaining the performance needed for a great brew.

Why This Matters for Your Cup

For many people searching for plastic free tea bags, the goal is simple: avoiding unnecessary plastics in their daily routine.

While some tea bags rely on synthetic sealing agents, BOS uses plant-based materials that support a more natural brewing experience. It’s part of our ongoing commitment to keeping rooibos as close to nature as possible.
