Polyweld filter bags hold a distinct advantage over all types of needle-sewn bags. The welded seams completely eliminate the possibility of unfiltered liquid bypass occurring due to needle holes. The result is a tighter seam, high bag efficiency and improved finish product yields. In addition, the fused edges of the Polyweld bag provide a fiber-free finish and virtually eliminate unwanted fiber migration. Since the Polyweld bag is not constructed with thread, the possibility of silicone contamination from this source is also removed. FSI’s Polyweld filter bags are available in several different media: standard polypropylene felt, extended life polypropylene felt, and standard polyester felt.
