Woven from high-clean virgin raw materials with full-area conductive yarn for anti-static performance. The bag surface sheds no tiny fibers and features extremely low chemical precipitation. Matched with high-purity clean PE inner liners, the whole production process is dust-free to strictly control dust contamination of lithium battery powder. All lifting loops and stitching adopt low-precipitation auxiliary materials. Dimensions and discharging structures are customized to fit silo interfaces of lithium battery production lines. Cleanliness and anti-static test reports are provided upon delivery.
