Nonwoven Polypropylene bag filters
We manufacture polypropylene filter bags for solid/liquid filtration, which are perfect for a temperature no higher than 80°C. Also, in applications demanding the chemical resistance for acid and alkalis. Polypropylene filter bags are calendared and thermally stabilized to prevent migration of fibers into the filtrate. They are produced most often in four standard sizes and are finished with steel snap ring or plastic self-sealing collar. Also available are non-standard filter bags and customized sizes and finishes with various options e.g., with tape, string, reinforcing, double handles, cylindrical bottom, V-shape bottom and many more, which we can produce in some working days as a manufacturer.

Polypropylene nonwoven felt meets the EU/FDA regulations, it is treated with a glazed finishing surface to reduce fiber migration. Polypropylene material is perfect for removing both solid and gelatinous particles, it has high dirt loading capacity and is silicone free.
