Double U-Strap Dustproof FIBC Bag for Iron Powder - China Suppliers & Factory for Industrial Mineral Packaging
Detailed Description
Dual Protective Sealing
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.
Automated Spouts & Dust Cover
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.
Customized Specifications
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.

Frequently Asked Questions (FAQ)
The double U-strap configuration distributes the extreme density and weight of mineral powders evenly across the body of the bag. This provides balanced load dispersion, minimizes strap stress fractures, prevents stitching loosening, and guarantees stable lifting and stacking during long-distance transportation.
It utilizes dual protective sealing technology, combining an internally coated woven fabric barrier with an independent high-tightness PE inner liner. This dual barrier prevents micro metallic particles from penetrating fabric gaps and eliminates dust flying during handling.
The bottom dust cover prevents powder overflow and dust emission during unloading operations. Additionally, during warehouse stacking and storage, it shields the discharge spout from airborne contaminants, moisture, and debris, preserving the purity of the raw material.
Yes. While our standard specification is 70×70×100cm with a 1.5-ton rated load capacity, we offer complete OEM/ODM customization for bag dimensions, safe working load (SWL) ranges, spout types, liner specifications, and custom surface printing (logos, safety reminders, product specifications).
This FIBC is engineered for high-density, fine-particle applications including iron powder manufacturing, iron ore processing, metallurgical smelting, chemical mineral turnover, and heavy-duty bulk industrial storage.
Yes. Built under rigorous quality control with reinforced stitching, uniform coating, and high tensile-strength materials, these FIBCs are designed for dependable multi-cycle turnover and factory reuse.
