Made of high-density woven ultra-fine denier yarn with tiny fabric pores, matched with full-size thick anti-seepage PE inner film. The sewing stitch spacing of the bag body is densely reduced to block leakage of micro-fine powder through stitch gaps and fabric pores.
Double tie sealing is adopted for filling and discharging spouts, leaving no powder leakage dead corners across the whole bag. No dust spills out during lifting jolting and long-distance transportation, which avoids raw material loss and waste while improving the dust environmental condition of workshops.
