These circular FIBC bags, also known as tubular bulk bags or jumbo bags, are engineered for the safe handling and transportation of fine powders and heavy mineral materials such as chemical powders and iron ore sand. Designed with a focus on strength, sealing performance, and operational efficiency, they are widely used in industries including chemicals, mining, and bulk material processing.

The bag features a circular (tubular) construction, which eliminates side seams and enhances structural uniformity. With a standard dimension of 90 cm diameter and 100 cm height, this design ensures optimal volume utilization while maintaining stability during stacking and transport. The safe working load reaches 1.5 tons, making it suitable for medium to heavy-duty applications.

To prevent material leakage, the bag is equipped with integrated leak-proof sealing strips, which significantly improve containment performance for fine powders. This makes it an ideal solution for bulk bags for chemical powders, mineral powders, and other flowable materials that require clean and secure packaging.

The lifting system adopts cross corner lifting loops combined with two reinforced circumferential belts, providing balanced load distribution and enhanced safety during lifting operations. The lifting loops are manufactured with approximately 60g/m high-strength PP woven straps, ensuring reliable performance under heavy loads. This structure is compatible with forklift and crane handling, improving efficiency in industrial environments.

The top is designed with a filling spout (top inlet) for controlled and efficient loading, while the flat bottom allows stable stacking and easy storage. These design elements make the bag suitable for bulk material handling, warehousing, and export logistics.

As an experienced FIBC manufacturer and bulk bag supplier, we offer flexible OEM and ODM services. Customers can customize specifications including size, fabric weight, lifting loop configuration, color, and printing. Our production process follows strict quality control standards, ensuring that every bag meets the requirements of industrial bulk packaging and global supply chains.

These heavy duty FIBC bags provide a reliable and cost-effective solution for companies seeking safe packaging for chemical raw materials, iron ore, sand, and other bulk commodities.
