tea bag is a small, porous, enclosed pouch or package containing dry plant material, soaked in boiling water to make tea or infusion. Classically this is the tea leaf (Camellia sinensis ), but this term is also used for herbal teas (tisanes) made of herbs or spices. Tea bags are generally made of filter paper or food grade plastics, or sometimes from silk. The bag contains tea leaves while the tea is soaked, making it easier to remove the leaves, and perform the same function as the infusion tea. Some tea bags have a string section attached with a paper label at the top that helps remove the bag while also displaying a brand or tea variation.
In countries where the use of loose tea leaves is more common, the term "tea bag" is usually used to describe paper or foil packaging for loose leaves. They are usually square or rectangular envelopes with brand names, flavors and decorative patterns imprinted on them.

Histori
Packaging tea on paper back to the 8th century 8th century China, during the Tang Dynasty when the paper folded and sewn into square bags to preserve the aroma and aroma of tea. Then the paper tea bags are stitched from all sides to create a protective casing for tea leaves.
The first modern tea bag in the Western World is a hand-stitched handbag; date of patent tea patent as early as 1903. First appeared commercially around 1904, tea bags successfully marketed around 1908 by tea and coffee importer Thomas Sullivan from New York, who sent his silk tea bags all over the world. The loose tea is meant to be taken out of the pocket by the customer, but they find it easier to brew tea with tea still covered in porous pockets. The first tea bag packing machine was invented in 1929 by Adolf Rambold for the German company Teekanne.
Modern tea bags are usually made of paper fibers. The hot sealed paper fiber paper bag was patented in 1930 by William Hermanson, one of the founders of the Technical Papers Corporation of Boston, who sold his patent to the Salada Tea Company.
A rectangular tea bag was not discovered until 1944. Before this, the tea bag resembled a small sack.

Production
Tea
Various types of tea and other infusion drinks such as herbal teas, available in tea bags. Typically, tea bags use fannings, left-overs after larger pieces of leaves are collected for sale as loose tea, but some companies sell tea bags containing intact leaf tea.
Paper
Paper bags are related to paper found in milk and coffee filters and are a mixture of wood and vegetable fibers. The latter is a bleached abaca pulp pulp, planted banana plantations grown for fiber, mostly in the Philippines and Colombia. Some bags have heat-sealable thermoplastics such as PVC or polypropylene as the component fibers on the inside surface of the tea bag. Tea paper bags are usually sealed using polypropylene.
Plastic removal
In 2017, Mike Armitage, a gardener in Wrexham, England, found that tea bags leave plastic residue after being composted. He started a petition to urge Unilever to dispose of plastic from bag production. In January 2018, Co-op Food announced that they were removing plastic from their own brand of tea bag 99 along with their supplier, Typhoo. In February 2018, PG Tips announced that their pyramid bag is now using corn starch adhesive instead of polypropylene.
Tea bag maker
Some of the leading tea bag production machines are MAI from Mar del Plata, Argentina; Teepack from Meerbusch, Germany; and IMA, from Bologna, Italy. A standard machine manufactured by a MAI company can fill 120 rectangular pockets per minute containing up to 3.3 grams per bag, allowing herbal tea packaging. Another company, Tecnomeccanica Italia, has a faster design that is capable of filling 250 tetrahedral bags per minute.
Shape and use
Traditionally, tea bags are square or rectangular. Recently round and tetrahedral bags have been present in the market and are often claimed by their manufacturers to improve the quality of beverages. Environmentalists prefer silk to nylon because of health problems and biodegradability. Another ingredient for tea bags is Soilon, made from corn starch. Empty empty teas are also available for the consumer to be filled with the tea leaves themselves. This is usually an open bag with a long flap. The bag is filled with the exact amount of tea leaves and the lid is sealed into a bag to keep the tea. Such tea bags combine the ease of use of commercially produced tea bags with a wider selection of teas and better quality loose tea controls.
Coffee bag
The concept of measurable parts for inclusion in disposable bags has also been applied to coffee in the form of coffee bags, although this has not yet achieved such a wide acceptance of tea bags.
Decorative tea bag labels have become the basis for large collections and collectors collect tea bags from around the world.
The folding of teabag begins in the Netherlands and is often credited to Tiny van der Plas. It is an origami form in which identical patterned paper boxes (cut from the front of the tea bag wrapper) are folded, and then arranged in the form of roses. These roses are usually used to decorate gift cards and have been a popular craft in the US and UK since 2000.
