Tea bags, as the name suggests is paper or cloth wrapped in tea, you can store for a long time.
In June 1908, New York tea merchants Thomas Sullivan often sent samples of tea to potential customers. In order to reduce costs, he thought of a way, that is, a little loose tea in a few small bags of silk inside. At that time some of the customers did not bubble tea after receiving those silk bags,Because the procedure for brewing tea is unclear, Put the silk bag clonk to throw in boiling water. Gradually, people found that the tea bag so easy to use, they gradually formed a small bag of tea with the habit. The original tea bag uses a silk bag. Later, Boston businessman William Hermanson invented the heat-resistant paper fiber tea bag, in the material closer to the modern tea bag. At first these American tea bags are single-bag shape, because the form is simple, the use of packaging machinery is relatively simple, these tea bags into the water, tea will be concentrated in the tea bag, brewing speed is very slow. Later, some people will be folded into the middle of the tea into the W-type double-bag tea bag which found to speed up the hot tea in the rate of brewing. In 1949, Teepack of Germany produced the world's first fully automated double-bagged tea bag machine with this concept. Since then this package began to be popular in Europe, some old tea merchants such as twinning and Whittard more use of such packaging.
The original tea bag is a simple box single capsule shape, this kind of tea bag into the water, tea will be concentrated in the tea bag, brewing speed is very slow. But because the form is simple, the use of packaging machinery is relatively simple, so still used for most businesses.
With the popular fruit and tea, ordinary tea bags because of the small space, can not accommodate the expansion of fruit and petals, the market began to appear diamond tea bags. Diamond tea bag as the name suggests is like a diamond, was tetrahedron structure, the use of food grade nylon for packaging. This kind of tea bag exquisitely carved, and the bag space is large, conducive to the distribution of fragrance, but also can watch the morphological changes in tea is the mainstream of the future trend of tea bags. But the diamond tea bag processing costs are high, very few factories can produce. So most of the more high-end products. Domestic 7talks all use diamond tea bags.
In addition, there are some alien tea bags. In the diamond tea bag on the basis of some exaggerated adjustments. This kind of tea bag although the shape of novel and interesting, but the processing is extremely complex, very few brands used.
The emergence of tea bags is not to reduce or enhance the quality of tea, but to facilitate the carrying and brewing, more is to take advantage of convenience. Naturally inevitable to damage the shape of the tea. But for the outdoors outside the tea lovers, tea bags also have its superiority.
