Plastic-free and sustainable
Organic blends in plastic-free pyramid bags, so no microplastics steep into your cup
Most tea bags contain plastic, which can shed microplastics into your cup when steeped in hot water. The best plastic-free tea uses plant-based bags instead. Sippo's pyramid bags are Soilon, a cornstarch-based mesh, holding real, organic, visible ingredients, with no added sugar or flavouring. A cleaner cup for you, and less plastic waste, plainly explained.
It surprises most people that the standard tea bag often contains plastic, and that steeping it in boiling water can release microplastics into the cup. The fix is simple: a plant-based, plastic-free bag. Sippo's pyramid bags are plastic-free, and this is an honest account of what that means and why it matters.

What's inside, and why
Found in: All Sippo teasTraditionalPlant-based mesh
Our pyramid bags are Soilon, a plant-based mesh made from cornstarch rather than nylon or PET, so no microplastics steep into your cup and there is no hidden plastic to throw away. Roomy enough for real ingredients to open.
Found in: All Sippo teasTraditionalWhole cut botanicals
Whole, visible cut ingredients rather than dust, all certified organic. What you see in the bag is what brews in the cup.
Found in: All Sippo teasTraditionalNothing artificial
The flavour comes from the fruit, herbs and spices themselves, so there are no synthetic additives going down the drain either.

Outside-in routine pairings
Our tea bags are plastic-free, and so is our exfoliant.

Many do. Standard tea bags are often sealed with polypropylene, and some premium mesh bags are made of nylon or PET, all plastics. Research has shown plastic tea bags can release microplastics into the brew when steeped in hot water. Sippo's pyramid bags are plastic-free to avoid this.
Soilon, a plant-based pyramid mesh made from cornstarch rather than nylon or PET plastic. It is roomy enough for the real, organic, cut ingredients to open and brew properly, with no plastic to steep into your cup and none to throw away.
We aim for it across the board: plastic-free bags, certified-organic real ingredients, no added sugar or synthetic flavouring, and small-batch blending in Sydney rather than mass production offshore. No product is perfect, and we keep working at it, but it is genuinely lower-impact from leaf to bag.
Yes. Mint Condition exfoliates with sugar and salt rather than the plastic microbeads many scrubs still use, so nothing plastic washes down your drain either. We cover that in its own guide.
Plastic-free tea, in depth
It catches most people off guard: a large share of tea bags contain plastic. Many paper bags are heat-sealed with polypropylene, and some of the silky premium pyramid bags are made from nylon or PET. Studies have found that steeping plastic tea bags in hot water can release significant numbers of microplastic particles into the brew. For something you drink daily, that is worth avoiding.
Sippo uses Soilon pyramid bags, a plant-based mesh made from cornstarch rather than the nylon or PET that most silky pyramid bags are made of. They are roomy enough for the real, whole, cut ingredients we use to open and brew properly, and because there is no plastic, there is nothing to shed into your cup and no plastic to throw away afterwards. It is a simple swap that removes a daily, invisible source of plastic.
A genuinely sustainable tea has to follow through past the bag. Our blends are certified organic with real, visible ingredients rather than dust, there is no added sugar or synthetic flavouring, and everything is hand-blended in small batches in Sydney rather than mass-produced and shipped from offshore. None of it is perfect, and we keep working at it, but from the bag to the blending it is built to tread more lightly.
It runs through the body care too. Mint Condition exfoliates with unrefined sugar and pink salt, never the plastic microbeads still used in many scrubs, so no plastic washes down your drain. Plastic-free in the cup and plastic-free in the shower, from the same small local team, with real organic ingredients throughout.
