The difference between hot melt filter bag and thread seam filter bag

The difference between seam bag body and hot melt bag body

Thread seam filter bag: The use of sewing technology to sew the ring, sewing material polyester or polypropylene line, the main features of affordable, high production efficiency, low cost, in the non-target filter bag production has a great advantage. The main application areas are food and beverage, water treatment, pharmaceutical solvents, textile industry and so on.

Hot melt filter bag: made of hot fusion production process, the main feature of hot melt filter bag is that the surface is treated by special singeing, which effectively prevents the fiber from falling off and extends the service life. The main application areas are ink coating, metal plating solution, water treatment, automotive coating and so on.

The difference between thread top and hot melt top

Thread stitching on the loop: is a more traditional pattern of the loop. Because the sewing machine needle needs to penetrate the mouth of the plastic rubber ring, if the penetration is too compact, the ring is easy to fall off in the work, and the penetration is too sparse, which will cause filtrate leakage. Filter bag ring ring is generally selected stainless steel ring, galvanized ring, PP or PE plastic ring.

Hot melt upper ring: The use of hot melt technology, the non-woven fabric and plastic rubber ring perfect fit, this welding process, sealing is particularly good, to solve the phenomenon of liquid leakage filter, is to solve the filter bag ring mouth treatment of a new breakthrough. The ring mouth ring is made of stainless steel ring, galvanized ring and plastic ring like the thread sewn filter bag.
