About this product

Product information from the supplier.

The U Panel Big Bag is a premier industrial packaging solution specifically engineered for the high-efficiency handling and transportation of bulk materials. By utilizing a specialized U-panel structural design, these bags eliminate the common "ballooning" effect, ensuring a squared-off shape when filled. This architectural advantage maximizes warehouse cubic space and provides superior stability for secure stacking during long-distance transit.

Manufactured from high-grade, heavy-duty polypropylene (PP) woven fabric, our U Panel bags are built to withstand the most rigorous industrial environments. Combining exceptional tensile strength with versatile filling and discharging options, they serve as the ideal storage and transport medium for chemicals, minerals, agriculture, and construction materials requiring high-volume, secure containment.

Frequently Asked Questions

Q: What is the primary benefit of a U Panel design over a standard Big Bag?

The U Panel design provides internal reinforcement that forces the bag to maintain a square shape when filled. This prevents the "ballooning" effect, allowing bags to be stacked more securely and maximizing container volume.

Q: Can U Panel Big Bags be customized for specific materials?

Yes, we offer full customization including varied dimensions, safe working loads (SWL), UV stabilization for outdoor use, and PE inner liners for moisture-sensitive products.

Q: What is the Safety Factor (SF) of these bags?

Our bags typically come with a 5:1 safety factor for single-trip use and a 6:1 safety factor for multi-trip applications, ensuring maximum safety during lifting and transport.

Q: Are these bags suitable for food-grade or chemical products?

Absolutely. We use virgin PP materials and can provide food-grade certifications and specialized liners to ensure zero contamination for sensitive chemical or food ingredients.

Q: How do I choose the right size for my bulk material?

Size selection depends on the bulk density of your material. We recommend providing the weight and the density (kg/m³) so our engineers can calculate the optimal dimensions for you.

Q: Do you provide UV protection for bags stored outdoors?

Yes, all our PP woven bags can be treated with UV stabilizers during the extrusion process, preventing the fabric from degrading under prolonged sunlight exposure.
