BPONG filter bags are among the most frequently used solutions on the market for liquid filtration, made from high-quality polypropylene felt. This product features advanced manufacturing technology and excellent chemical resistance, distinguishing it from polyester bags.

Construction and Manufacturing Technology
A key feature of BPONG bags is their fully welded construction.

• No Seams: The production process joins the material without the use of needles or staples, completely eliminating "bypasses" (uncontrolled flow of contaminants through needle holes).

• Leak-proof: Welded seams ensure high tightness, which directly translates to increased filtration efficiency and improved quality of the filtered liquid.

• Surface Finish: The bags have a smooth surface (WE finish – singed, calendared, heat-treated), which effectively prevents fiber migration into the filtrate.

Chemical and Thermal Resistance
The polypropylene material (BPONG) stands out with superior chemical resistance to acids and bases, as well as cost-effectiveness compared to polyester.
