The standard cylindrical FIBC adopts an integrated barrel structure. Unlike square bulk bags, it has no sharp corners or dead corners with smooth and rounded surfaces, fundamentally solving the problems of concentrated stress and partial abrasion damage at the edges of square bags. It is equipped with four sets of high-strength lifting loops evenly arranged around the bag mouth and features a fully sealed flat bottom for stable standing. Made of thickened PP woven fabric, the bag bears force evenly. It keeps full and tidy after filling without partial bulging or tight areas. Customizable overall height and barrel diameter are available to match different loading capacities and material sizes. Designed mainly for granular, spherical and round materials, it is widely used in packaging, transportation and storage of feed, fertilizer, grain pellets, chemical spherical particles and plastic pellets, serving as a mainstream FIBC dedicated to granular materials.
It boasts excellent anti-expansion performance. The cylindrical structure disperses material pressure, so the bag is not easy to split or deform when fully loaded. The fabric bears stress evenly without local stress concentration, greatly reducing the risk of partial damage and abrasion. It achieves high filling rate with much higher space utilization than ordinary square FIBCs, leaving no dead space for materials. Wear-resistant, durable and anti-aging, it can be recycled many times. Suitable for granular and spherical materials, it prevents material jamming and accumulation for thorough residue-free discharging. Customizable in multiple specifications to meet different load requirements with great practicality.
