In June 1908, New York tea merchant Thomas Sullivan often sent tea samples to potential customers. In order to reduce costs, he thought of a method that is to put a little loose tea leaves in several small silk bags.
At that time, after receiving the silk bags, some customers who had not brewed tea at that time often threw these silk bags into the boiling water because they did not know the procedure of making tea. But gradually, people found that the packed tea was convenient and easy to use, and gradually formed the habit of wrapping tea in small bags.
The original tea bags used silk bags, and the cost was quite high. Later, Boston businessman William Hermanson invented the heat-resistant paper fiber tea bag, which is closer to the modern tea bag in material.
At first, these American tea bags were single-bag styles. Due to the simple form, the packaging machinery is relatively simple. Put this type of tea bags in water, the tea leaves will be concentrated in the tea bags, and the brewing speed is very slow. Later, someone packed the tea into a double-bag tea bag folded into a W shape, and found that it can speed up the brewing rate of tea in hot water.
