While the double-chamber tea bag has been a luxury product for many years, in recent years it has increasingly become the standard in very many countries around the world and dominates many markets. And even in developing countries, the preference for this high-quality type of bag is constantly increasing.

The filter paper of a good double-chamber tea bag is organic, and the tea bag is closed only by mechanical squeezing and folding. Therefore, it does not contain the chemical additives or adhesives that a simple sealed tea bag requires to seal the filter paper. Comparing the shape of a flat single-chamber bag with the "three-dimensional" double-chamber bag, it becomes immediately clear that the tea in the double-chamber bag can release its aroma to the water much better. In practice, a double-chamber bag yields up to 30% more flavor in the same brewing period. For this reason, a cup with the same amount of tea is more flavorful or, conversely, develops the same flavor with less tea.

The 2 chambers of the double-chamber bag make it possible to pack twice as much filling volume into one bag and are indispensable for suppliers of many fruit or herbal teas, because only with this method can the necessary volume be filled.
All materials (filter paper, cotton thread, and aluminum staples, if applicable) of which the double-chamber bag consists are completely harmless from an environmental point of view. Even after the tea bag has served its purpose and ends up on the compost heap or in the organic waste bin, it will not pollute the environment, but will decompose back into its original organic substances or clay.
