Our factory completed the upgrade of circular weaving production lines and product quality inspection systems. High-precision electronic weighing equipment and tensile testers were newly introduced, and the weaving technology of mesh bags was optimized. After the upgrade, gram weight deviation of mesh bags is further reduced, and defects such as loose yarn and broken bags are minimized. We have built a full-chain quality control system covering raw material incoming check, weaving production, finished goods sampling and full-pack re-inspection. The stability of export mesh bags is improved to meet strict packaging quality requirements from clients in the Middle East and South America.
