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.
