Polypropylene bags are compatible with a broad range of corrosive fluids including organic solvents oils acids alkalis and microorganisms. The bags are manufactured from felt because of its high solids loading capabilities in comparison to similar mesh fabrics. The media is created by needle-punching two layers of synthetic fibers together in a supporting scrim. A glazed finish created by melting the outermost surface fibers is used to produce a bond that reduces the possibility of migration.
