Detailed Description
◈
High-Stability Construction: This specialized dustproof FIBC is purpose-built for storage, stacking and interregional shipment of ultra-fine iron powder, iron ore fines and metallic mineral dust. Adopting side-seam integrated lifting strap construction, the bag distributes heavy load evenly across vertical side panels, eliminating risks of stitching tear and strap detachment.
◈
Double-Layer Isolation: Architecture forms comprehensive barrier protection for fine iron particles. The polypropylene woven fabric is covered with internal coating film to stop tiny particulates from seeping through textile gaps, while a separate sealed PE inner liner acts as secondary isolation to further avoid leakage under vibration.
◈
Dust-Free Operation: Compact small spouts are arranged at the top and bottom separately, supporting fully sealed dust-free feeding on automated production lines and controlled discharge during raw material processing.
◈
Custom Fitted Dust Cover: Attached at the bottom outlet as a core functional component. It blocks micro iron powder from leaking during unloading to cut waste and covers the outlet during stacking to prevent external contamination.
◈
OEM & Industrial Customization: Supports customized bag dimensions, adjustable safe working load ranging from 500kg to 2500kg, multi-color surface printing of brand logos, and batch tracking codes.
Manufacturing workshops operate with unified quality inspection standards. Every mineral FIBC undergoes tensile strength testing, coating tightness inspection and dust leakage verification before shipment. This side-seam dustproof bulk bag is widely used among iron ore concentrators, metal smelting manufacturers and metal mineral raw material traders across global markets.
Frequently Asked Questions
What is the maximum load capacity for these bags?
Our FIBCs support a safe working load (SWL) ranging from 500kg up to 2500kg, depending on your specific requirements.
How does the bag prevent ultra-fine powder leakage?
We utilize a double-layer protection system involving internal coating film on the woven fabric and an additional sealed PE inner liner.
Can the dimensions and spouts be customized?
Yes, we offer full OEM services to adjust bag dimensions, spout specifications, and lifting strap layouts to match your facility's workflow.
What is the function of the bottom dust cover?
It serves two purposes: preventing powder leakage during discharge and protecting the raw material from external contamination during storage.
Do the bags undergo quality testing?
Every batch undergoes rigorous tensile strength testing, coating tightness inspection, and dust leakage verification before shipment.
Is these bags suitable for international shipping?
Absolutely. The side-seam integrated lifting design and durable construction are optimized for stacking and long-distance interregional logistics.
