Depth Filtration
The three-dimensional felt structure captures a broad range of suspended solids and can retain particles within the media thickness.
Polypropylene Liquid Filtration
Polypropylene (PP) Filter Bags
Reliable, economical and chemically resistant filtration for industrial liquids. Ince manufactures polypropylene filter bags in a wide range of micron ratings, sizes, ring styles and seam constructions for demanding process filtration.
Product Overview
What Are Polypropylene Filter Bags?
Polypropylene filter bags are widely used for cost-effective liquid filtration where chemical resistance, solids-holding capacity and dependable particle removal are required. The filter media is typically made from polypropylene felt, a depth filtration material that captures contaminants throughout the thickness of the fabric rather than only on the surface.
Ince PP filter bags are designed for use in standard bag filter housings and can be supplied in multiple micron ratings, bag dimensions, ring styles and seam constructions. They are suitable for water treatment, chemicals, coatings, food processing, metal finishing and many other industrial processes.

Why PP Filter Media?
Key Advantages of PP Liquid Filter Bags
Polypropylene combines practical filtration performance with an attractive total cost of ownership for many industrial applications.
Chemical Compatibility
PP media performs well with many commonly used industrial fluids, making it a versatile choice for process filtration.
Efficient Flow
Proper media selection provides a useful balance between contaminant retention, flow rate and operating pressure drop.
Low Fiber Migration
Glazed or singed surface treatments can help reduce fiber release in applications that require cleaner downstream fluid.
Multiple Construction Options
Choose sewn or welded seams, plastic or metal rings, and standard or customized dimensions.
Cost-Effective Supply
Factory-direct manufacturing supports volume orders, regular replacements and private-label procurement programs.

Frequently Asked Questions
PP Filter Bag FAQ
What is a polypropylene filter bag used for?
A polypropylene filter bag is used to remove suspended solids from industrial liquids. Typical applications include water treatment, chemical processing, paints and coatings, metal finishing, process fluids and general industrial filtration.
What micron ratings are available for PP filter bags?
Common options include 1, 5, 10, 25, 50, 75, 100, 150 and 200 micron. Custom ratings may also be available depending on media and order requirements.
What is the difference between PP felt and mesh filter bags?
PP felt is generally used for depth filtration and higher dirt-holding capacity, while mesh media primarily retains particles on the surface and is commonly selected for coarser filtration or applications where a more defined opening size is preferred.
Can Ince make custom PP filter bags?
Yes. Custom options can include dimensions, micron rating, ring or collar style, seam construction, labels, logo printing and packaging for OEM or private-label orders.
How do I choose the right PP filter bag?
Consider particle size, target cleanliness, fluid chemistry, operating temperature, viscosity, flow rate, pressure drop and filter housing dimensions. Providing these details helps us recommend a suitable configuration.
