Signs of a Good Teabag: AVANTCHA Silk Teabags

While convenience is often the reason people choose teabags over loose leaf tea, quality and sustainability should never be compromised. The best tea bags, whether green or herbal or other, offer a clean, full-flavoured cup without microplastics, synthetic materials, or tea dust.

If you’re curious about tea bag safety, or wondering which tea is best, here are five signs of a premium tea bag that’s truly worth steeping.

1. Plastic-Free

Most supermarket teabags contain hidden plastics in the mesh or sealed edges. A high-quality, plastic-free tea bag avoids petroleum-based materials, protecting your health and the planet. If you’re looking for eco-friendly tea bags, AVANTCHA is where to look.

2. Glue-Free and Staple-Free

Glue and staples are often used in mass-market tea bags, making them non-compostable and less safe for steeping. A compostable tea bag should be heat-sealed or hand-tied, no glue or metal, ensuring a clean brew.

3. Non-GMO Sugarcane Mesh

Top-tier disposable tea bags use biodegradable, non-GMO sugarcane mesh. This plant-based material allows for optimal water flow, unlocking full flavour and aroma, especially important when brewing green tea bags or herbal tea bags, where clarity of taste matters.

4. Natural Cotton Thread

A detail often overlooked, the thread used to attach the tag can also impact sustainability. High-quality teabags will use natural cotton threads rather than nylon or polyester, offering a completely plastic-free experience from top to bottom.

5. Paper Tag

A simple paper tag, uncoated and free of gloss, makes a teabag easier to compost. It also reflects a commitment to minimal, thoughtful design. By avoiding foil or plastic coatings, it ensures that every element of the teabag breaks down naturally.

Why AVANTCHA Teabags Taste Better

Flavour in tea should be an art not an afterthought. Unlike most mass-produced teabags that rely on synthetic granules or artificial flavour powders to mimic natural aromas, AVANTCHA uses only pure, natural ingredients (herbs, flowers, fruits, roots, seeds and spices) and real flavour extracts and essential oils to gently scent and enhance our teas.

This delicate, artisanal approach preserves the integrity of the tea leaves themselves, allowing you to experience the true character of each origin, with layered aromas that smell as authentic as they taste.

Where industrial flavouring can coat leaves in artificial granules that lose potency over time, our natural oils bond lightly to the tea, releasing their full complexity upon infusion. The result? A cup that truly smells and tastes alive, with no harsh edges or artificial sweetness. Just pure harmony between leaf and flavour.

Sustainability Without Compromise

We believe that sustainability should never come at the cost of freshness, hygiene, or shelf life. Every element of our AVANTCHA Silk Teabags is designed to balance eco-responsibility with the protection and longevity of the tea inside.

Our teabags are made from biosilk derived from non-GMO sugarcane, a fully biodegradable material that allows optimal infusion while being kind to the planet. The tag and thread are paper and natural cotton, ensuring a plastic-free tea bag experience from top to bottom.

For freshness, the outer envelope currently includes a thin layer of plant-based PLA, which acts as a moisture and oxygen barrier: essential for preserving the delicate natural aromas of our teas.

But our innovation continues: we’re developing an entirely degradable tea envelope, launching in 2026, that will use a micron-thin degradable aluminium layer and PBAT* for full compostability without compromising on quality or hygiene.

Because great tea must be both pure and responsible, crafted with respect for nature at every stage, from how we flavour it to how it’s sealed.

*PBAT (polybutylene adipate terephthalate) is a biodegradable, compostable polymer made from renewable and fossil-based sources, designed to break down naturally without leaving microplastics, while offering the flexibility and durability needed to protect food-grade products like tea.
