A tea bag is a small, porous paper, silk or nylon bag containing tea leaves for brewing tea. The tea remains inside the bag as the tea is brewed, making it easier to dispose of the leaves – a function which is often made easier by attaching a string with a paper label to the top. Thus a tea bag serves the same function as a tea infuser.
In countries where the use of loose tea leaves is more prevalent the term tea 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.
History
The first tea bags were made from hand-sewn silk muslin bags and tea bag patents of this sort exist dating as early as 1903. First appearing commercially around 1904, tea bags were successfully marketed by tea and coffee shop merchant Thomas Sullivan from New York, who shipped his tea bags around the world. Modern tea bags are usually made of paper fiber.
Production
Tea bag paper is related to paper found in milk and coffee filters. It is made with a blend of wood and vegetable fibers. The vegetable fiber is bleached pulp abaca hemp, a small plantation tree grown for the fiber, mostly in the Philippines and Colombia. Heat-sealed tea bag paper usually has a heat-sealable thermoplastic such as PVC or polypropylene, as a component fiber on inner side of the teabag surface.
Tea bag shapes
Traditionally, tea bags have been square or rectangular in shape. More recently circular and pyramidal bags 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. Certainly preparations of tea with a teabag in a cup often results in poor infusion time.[citation needed]
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 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.
Criticism
A well-produced tea bag, with enough space for the tea to infuse properly, is a convenient alternative to loose leaves. On the other hand, cheap tea bags may contain poor quality tea — small, dusty leaves from many different sources ('floor sweepings') which tend to release tannin more quickly, making the tea taste harsh.[citation needed]
Some tea drinkers claim that loose leaves brew a superior cup of tea, and believe that the ritual of handling the leaves is part of the experience of your tea.
Coffee
The concept of pre-measured portions to be infused in disposable bags has also been applied to coffee, although this has not achieved such wide market penetration (similar to the market penetration of instant tea as compared to instant coffee).
Other uses for tea bags
Decorative teabags have become the basis for large collections, and also for the hobby of teabag folding. Begun in the Netherlands, and often credited to Tiny van der Plas, teabag folding is a form of origami in which identical squares of patterned paper (cut from the front of teabag sachets) are folded, and then arranged in rosettes. These rosettes are usually used to decorate gift cards and it has become a popular craft in both the US and UK since 2000.[1]
