The U-panel Baffle Bulk Bag is a large-scale flexible container designed for the storage and transportation of bulk materials. Characterized by its unique U-shaped panel structure and internal baffles, this bag offers enhanced stability and load-bearing capacity compared to standard bulk bags. Constructed from high-strength woven polypropylene fabric, it is engineered to handle various granular, powdery, or block materials, providing a cost-effective solution for industrial and agricultural logistics. The U-panel design distributes weight evenly across the bag’s surface, while the internal baffles prevent excessive expansion during filling, maintaining a compact shape for efficient stacking and transportation. Suitable for both indoor storage and outdoor shipping, it meets common industry standards for safety and durability.

The bag features a U-shaped panel design, formed by integrating three woven fabric panels (one back panel and two side panels) into a continuous U-shape. This structure eliminates vertical seams on the sides, reducing the risk of tearing under heavy loads. The U-panel design enhances the bag’s overall tensile strength, with a maximum lateral load resistance of up to 500 kg per side, ensuring stability when stacked in warehouses or transport vehicles.
Equipped with 4 vertical baffles (one in each corner), the bag restricts horizontal expansion when filled. This maintains a rectangular shape, allowing for efficient use of storage space—stacking up to 5 units high without deformation. The baffles are made from the same woven polypropylene material as the bag, sewn securely to the inner walls to withstand internal pressure from bulk materials.
The main body is crafted from 100% virgin polypropylene with a fabric weight of 180–200 g/m², offering high tensile strength (minimum 16 kN/m in warp and weft directions). The material is resistant to moisture, mildew, and most chemical substances, making it suitable for both dry and semi-dry materials. Optional UV stabilization treatment is available, adding 0.5–1% UV inhibitors to extend service life in outdoor environments by 6–12 months under direct sunlight.
Designed with a Safe Working Load (SWL) of 1000–2000 kg, the bag has a 5:1 safety factor, meaning it can withstand a maximum breaking load of 5000–10000 kg. It is equipped with 4 lifting loops made from reinforced polypropylene webbing, each with a breaking strength of 2000 kg, ensuring safe handling by forklifts or cranes.
The U-panel Baffle Bulk Bag is widely used in various industries:
• Agriculture: For transporting and storing grains, seeds, fertilizers, and animal feed. Its moisture-resistant properties protect contents from humidity during long-term storage.
• Construction: Suitable for carrying sand, gravel, cement, and powdered mortar. The stable shape prevents spillage during transportation to construction sites.
• Chemicals: Used for non-hazardous powdered or granular chemicals, such as detergents, industrial additives, and plastic pellets, thanks to its chemical resistance.
• Mining: Ideal for transporting mineral ores, coal, and metal concentrates, with high load-bearing capacity meeting heavy-industry requirements.
The standard volume ranges from 500 to 2000 liters, depending on dimensions (typically 80x80x120 cm to 120x120x180 cm). Custom sizes are available upon request.
Yes, it can be reused 3–5 times under normal conditions, provided it is inspected for damage (e.g., tears, worn lifting loops) after each use. Heavy loads or sharp materials may reduce the reuse count.
Food-grade versions are available, made from FDA-approved polypropylene without harmful additives. These meet international food contact standards (e.g., EU 10/2011) and are suitable for grains, sugar, and other food products.
