China FIBC Suppliers - 4-Loop Jumbo Bulk Bag with 2 Handling Belts and Small Spouts | Custom Factory Solutions

Designed for universal industrial bulk material circulation scenarios, this square FIBC bag optimizes the lifting and carrying structure of traditional bulk bags to solve the pain points of unstable hoisting and inconvenient manual moving during daily factory operation. Its core lifting structure consists of four independent corner lifting loops matched with two extra transverse handling belts distributed on the upper part of the bag body. When forklifts lift the bag via four lifting loops, the stress can be evenly dispersed across the whole bag body, effectively preventing local stress concentration and fabric tearing during hoisting. The two extra handling belts bring great convenience for workers to move empty bags manually, greatly improving the turnover efficiency inside warehouses and production workshops.

This FIBC is built with small top spout and small bottom spout as standard configuration. The narrow-caliber spout design can reduce dust spillage while feeding and discharging powder materials, which not only keeps the workshop environment clean, but also cuts material waste caused by flying dust. Customers can connect the top spout to automatic feeding equipment and link the bottom spout with pipeline unloading devices, realizing fully sealed automated feeding and discharging without cutting open the entire bag body, which highly matches the production rhythm of modern automated factories. The whole bag adopts square woven structure, the bag body can keep upright after being filled with materials, so vertical stacking will not tilt or collapse, saving warehouse storage space and lowering the risk of collapse during storage.

We select high-tenacity virgin polypropylene woven cloth as the base material for this bulk bag, all stitching joints are reinforced by dense stitching technology to enhance the overall firmness of the FIBC. The product supports diversified personalized customization: buyers can adjust dimensions, safe working load, add PE/AL foil inner liners, change spout sizes or modify belt colors according to the physical properties of their bulk materials and on-site equipment conditions. Each finished bulk bag will pass lifting tension inspection and seam tightness test before delivery to guarantee stable quality for mass orders. This versatile FIBC is widely applicable for packaging and transportation of mineral aggregates, chemical granules, plastic raw materials, building fillers and other industrial bulk commodities, serving diversified packaging demands across manufacturing, mining, chemical and construction industries worldwide.
