Filter bag models are: 1 bag: 180*420 mm 2 bag: 180*810 3 bag: 105*230 4 bag: 105*380 5 bag: 150*520 Y series 202*330 other non-standard sizes.

Hot melt

The filter bag (PP PE liquid filter bag) produced by our company adopts advanced hot melt bonding technology to ensure that the filter bag has the best bonding strength and prevent leakage.


Our company’s agent filter bag sewing is very rigorous, firm and durable, the sealing effect of car seam joint play to the extreme. The pure sewing thread does not contain any lubricant components such as silicone oil, which avoids the problem of secondary pollution existing in ordinary sewing filter bags.

1, the use of non-silicone oil cooling high speed industrial sewing machine production, will not produce silicone oil pollution.

2. Lateral leakage caused by no high protrusion at the improved suture of the pouch opening is caused by no needle eye, resulting in lateral leakage. (Shanghai SFFILTECH PP PE liquid filter bag manufacturer)

3. The labels labeled with product specifications and models on the filter bag are all selected in a way that is easy to remove, so as to prevent the pollution of the filtrate by labels and ink in the use of the filter bag.

4, filtration accuracy range from 0.5 micron to 300 micron, the material is divided into polyester, polypropylene filter bag.

5. Argon arc welding technology of stainless steel and galvanized steel ring. The diameter error is less than 0.5mm, and the horizontal error is less than 0.2mm. The filter bag made of this kind of steel ring can be installed in the equipment to improve the sealing degree and reduce the probability of side leakage.
