Products Description
Our liquid PP filter bags deliver exceptional particle retention for chemical processing, water treatment, and food-grade applications. Manufactured using thermally bonded polypropylene fibers, these filter bags provide consistent 99.8% filtration efficiency down to 1 micron.
Key Technical Advantages:
- Chemical Resistance - Withstands acids, alkalis, and solvents (pH 0-14).
- Temperature Resilience - Stable performance from 32°F to 275°F (0°C-135°C).
- High Dirt-Holding Capacity - 25% greater particle retention vs standard needle felt bags.

Industrial Applications
Liquid PP Filter Bag tailored for industrial buyers
- Chemical Processing: Acid filtration, solvent clarification
- Food & Beverage: Edible oil polishing, syrup filtration
- Water Treatment: RO pre-filtration, desalination plants
- Pharmaceuticals: Process water purification
- Metalworking: Coolant filtration, parts wash systems
Can your PP filter bags handle high-viscosity fluids like polymer solutions or adhesives?
Yes - our gradient-density melt-blown construction maintains stable flow rates up to 500 cP viscosity. For optimal performance:
- Use 100-200 micron rating bags for fluids >300 cP
- Maintain operating temperature ≥104°F (40°C) for viscous media
- Specify reinforced polypropylene support mesh when ΔP exceeds 10 psi
Are these bags compatible with CIP (Clean-in-Place) systems in food processing plants?
Absolutely. Our FDA-compliant bags withstand:
- 30-minute CIP cycles at 185°F (85°C)
- 2% caustic soda or 1% nitric acid solutions
- Steam flushing at 15 psi maximum
Note: Always perform air blowdown (15-30 sec) before chemical cleaning
