All raw materials are natural white without any special bleaching and dyeing treatment, which fully meets environmental protection standards and effectively prevents fibers from falling off. Contaminated filtrate, high-strength long fibers make the filtration efficiency of the filter bag stable and have a longer service life.

    The ring, bottom and sides of the hot-melt filter bag are all made of seamless gaps, which avoids the pinholes caused by the seam filter bag sewing. They are all welded by hot-melt method to ensure that the welding at every point remains strong and consistent. It is suitable for the fields that require higher precision; to ensure that the filter bag is not affected by other production auxiliary materials, and to ensure the consistency of the material of each filter bag.
