Type A container bags are woven from polypropylene or other non-conductive materials. During the filling or unloading process, static electricity is generated due to the friction between the contents and the inner surface of the container bag. Type A container bags do not have electrostatic protection function and are strictly prohibited from being used for storing or transporting flammable materials or in flammable and explosive environments!


Type B container bags are similar to Type A and are also woven from polypropylene or other non-conductive materials. Like Type A container bags, there is no static dissipation mechanism. The difference is that its weaving material has a low breakdown voltage (≤ 6kV), which can prevent the occurrence of dangerous high-energy propagation brush discharge (PBD). Although Type B container bags can prevent the occurrence of spreading brush discharge, they cannot be considered anti-static container bags because they cannot dissipate electrostatic discharge. Ordinary brush discharge may still occur and can ignite flammable solvent vapors. Strictly prohibited for use in environments with flammable solvents or gases!
