Your first reply was quite disrespectful. I will try to give an honest answer.

Most modern tea bags are made on automated packaging machines designed and manufactured in Europe. Some fold and staple the bag (Lipton) and some apply heat to thermoplastic fibers embedded in the nonwoven teabag paper to seal the bag (Tetley). There are, of course, a number other methods. However, the two I have cited are the most typical methods used today.

The teabag cloth can either be a nonwoven paper, silk cloth (predecessor to nonwoven paper) or spunbond. All of these types of materials have carefully controlled pore structures that allow the hot water to penetrate and infuse the tea leaves but, at the same time, prevent most of the tea leave materials inside the bag from leaking out. The trick is to do this while the bag is submerged and yet the bag does not dissolve and fill the cup with messy tea leaves.
