Nylon mesh bag is a woven mesh bag made of food grade 100% monofilament nylon mesh through the process of seaming and welding.The nylon mesh bag has loose fibrous structure and superior gas permeability. It directly retains and adsorbs small particles, which can effectively capture fine solid and colloidal particles, and is not easy to block. The high-strength fiber filaments are criss-crossed to avoid breakage due to increased fluid pressure during filtration. It has the advantage features of high efficiency, low cost, large volume of dirt, and can be repeatedly cleaned.

Woven nylon mesh is made of nylon fibers and weaved them into a mesh screen. Nylon is made from synthetic polymer materials from polyamides, and is considered a thermoplastic material. It is one of the more frequently used polymer materials for a variety of products, in addition to being used for mesh screen. Nylon screen mesh is more wear resistance, chemical resistance, water resistance than polyester mesh screen.

There is a story about the invention of the tea bag. In 1900s, a New York tea merchant named Thomas Sullivan often sent samples of tea to potential customers. In order to reduce the cost, he thought of a way, that is to pack a little loose tea leaves in several small silk bags. At that time, some customers who had never made tea before received those silk bags, due to they were not very clear about the procedure of making tea, so they often threw these silk bags into the boiling water. But gradually, people found that the tea packaged in this way is convenient and easy to use, and gradually formed the habit of packaging tea in small bags. Later, someone suggested to him that the silk bag was too fine, so he switched to cotton gauze and officially sold it commercially.

During the filtration process of soybean milk production, bean dregs should be filtered. When coffee is ground, also it needs to filter the residue. Filtration is also required during juice production. These will all can be achieved with nylon mesh filter. With the nylon mesh filter, the residue can be filtered out, so that the taste of soy milk, coffee and fruit juice will be much better. Everyone can drink them more deliciously.
