Detailed Description
This heavy-duty industrial FIBC is specially designed for safe transportation, warehouse storage and automated material handling of fine iron powder, iron ore powder and micro metallic mineral particles. Adopting a robust double U-strap lifting design, this jumbo bag delivers balanced load dispersion and exceptional structural stability under heavy working conditions. Different from conventional single-loop lifting bags, the dual U-shaped belt construction reinforces the overall bearing performance, effectively resisting deformation, stitching loosening and strap stress fracture when fully loaded with high-density mineral powder materials. It ensures stable lifting, stacking and turnover for long-distance logistics and factory cyclic use.
Advanced Sealing Technology: To solve the common pain points of fine powder packaging such as particle leakage, dust flying and material contamination, this mineral-grade bulk bag adopts dual protective sealing technology. The outer woven fabric is processed with internal coating treatment to form a dense barrier layer that blocks tiny powder particles from penetrating fabric gaps. Matched with an independent high-tightness PE inner liner, the bag achieves full internal sealing, greatly improving the overall anti-leakage performance for superfine iron powder materials.
The bag is configured with standard top fill spout and bottom discharge spout, adapting to automated assembly line feeding, quantitative discharging and continuous material circulation in mineral processing plants. The upgraded bottom dust cover is a practical functional accessory for daily industrial operation. It effectively avoids fine iron powder overflow and dust emission during unloading operations, reducing material loss and keeping the working area clean. Meanwhile, it isolates outside dust, sundries and airborne pollutants during stacking and storage, preventing purified iron powder raw materials from secondary contamination and ensuring consistent material quality for downstream production.
This standard model comes with a dimension of 70×70×100cm and a rated load capacity of 1.5 tons, meeting conventional mineral bulk packaging standards. We provide comprehensive customized services to satisfy diverse industrial scenarios. Customers can adjust overall bag dimensions, customize safe working load within different weight ranges, and support personalized surface printing including brand logos, product specifications and safety reminders. Various bag styles, spout types and liner configurations are available for tailored packaging solutions.
All our mineral FIBCs are manufactured with standardized quality control procedures, with strict testing on stitching fastness, coating uniformity, dustproof performance and load-bearing safety. Suitable for iron powder processing, mineral smelting, chemical mineral raw material turnover and bulk industrial storage, this double U-strap dustproof bulk bag is a reliable reusable packaging option for global industrial manufacturers and mineral suppliers.
