Tea bags, as the name implies, are tea leaves wrapped in paper or cloth, which can be preserved for a long time or washed with water. Many tea bags are mostly filled with tea powder, but some brands will launch more high-grade tea bags.
origin
Thomas Sullivan, a tea merchant in new york, often sends tea samples to potential customers. In order to reduce the cost, he thought of a way, that is, put a little loose tea in several Suu bags. At that time, after receiving those silk bags, some customers who had never made tea often slammed them into boiling water because they were not sure about the procedure of making tea. But gradually, people found that the tea packaged in this way was convenient and easy to use, and gradually formed the habit of packaging tea in small bags. It was suggested to him that the silk package was too thin, so he changed it into cotton gauze and sold it officially. 1903, Sullivan applied for a patent for tea bags, and by 1920, tea bags were widely used in American catering industry.
The original tea bag used silk bags, which were expensive. Later, William Hermanson, a Boston businessman, invented a heat-resistant paper fiber tea bag, which was closer to modern tea bags in material. At first, these American tea bags were all single-bag-shaped. Because of their simple form and simple packaging machinery, when these tea bags are put into water, the tea leaves will be concentrated in the tea bags, and the brewing speed is very slow. Later, someone put the tea into a double tea bag folded into a W shape in the middle, and found that it could speed up the speed of making tea with hot water. 1949, the german Teepack company produced the world's first fully automatic double-bag tea packaging machine based on this concept. Since then, this kind of packaging has become popular in Europe, and some old tea merchants such as twinning and Whittard have also adopted this kind of packaging.
Before Joseph Tetley 1953 introduced teabags to Britain, teabags had been popular in the American market for decades.
