A tea bag is a small, porous paper, silk or plastic sealed bag containing tea leaves for brewing tea. The bag contains the tea leaves while the tea is brewed, making it easier to dispose of the leaves, and performing the same function as a tea infuser. Some tea bags have an attached piece of string with a paper label to the top that assists in removing the bag while also identifying the variety of tea.
In countries where the use of loose tea leaves is more prevalent, the term tea shoulder bag is commonly used to describe a paper or foil wrapper packaging for loose leaves. They are usually square or rectangular envelopes with the brand name and flavour printed on them, as well as interesting decorative patterns.
Traditionally, tea bags have been square or rectangular in shape. More recently circular and pyramidal shoulder bag have come on the market, and are often claimed by the manufacturers to improve the quality of the brew. This claim, however, only holds with a proper preparation.
A practical observation in the development of the tea shoulder bag from the traditional square, to the circular and finally the pyramidal bags is that the amount of adhesive used to seal the bags is reduced in each development. It could therefore be surmised that the development is not to improve the quality of the brew, but to reduce the cost of producing the bags themselves.
Empty tea bags are also available for consumers to fill with tea leaves themselves. These are typically an open-ended pouch with a long flap. The pouch is filled with an appropriate quantity of leaf tea and the flap is closed into the pouch to retain the tea. The resulting tea bag combines the ease of use of a commercially-produced tea bag with the wider tea choice and better quality control of loose leaf tea.
Because of the convenience of tea hobo bags, a wide variety of herbs can be purchased as “tea bag cut”, a grade which is specified in terms of the particle size, typically with the bulk of the leaves around 1 – 1.5 mm.
The nylon pyramidal tea bag containing tea leaf fragments instead of the tea “detritus” or dust made an appearance in the marketplace for aficionados. The pyramidal shape allows more room for the leaf to steep. Environmentalists prefer silk to nylon because of health and biodegradability issues. Another material for tea bags is Soilon, made from corn starch.
