Sewn / Welded Filter Bags -Non-Woven Polypropylene and Polyester

Sewn/Welded Filter Bags

Sewn/Welded Filter Bags

We offer Welded Flange Top and Welded Seams (Sewn) Filter Bags for Liquid Filtration. Impenetrable welded seams improve filtration and in conjunction with a glazed finish on the filter bag, greatly reduce or eliminate fiber migration. For certain applications, Welded seams offer an advantage over sewn seams.

The bottom, side, and Flange top of the Welded Seam Filter Bags for Liquid Filtration is completely welded.  No thread is used, and no sewing holes exist.

Although our standard Welded Seam filter bags are made with glazed media, plain media in many of the above micron ratings can often be provided.

With a wide range of micron sizes we can support and partner with many industries like chemical, food, paper, petroleum, adhesives, paints, water treatment, beverages, pharmaceutical and more !
