Developed to cope with the harsh working environment of construction sites and sand stock yards, this heavy-load U-panel FIBC solves fine sand seepage and premature edge wear. The U-shaped panel structure improves overall stereoscopic stability, allowing the bag to stand upright naturally without bulging or serious distortion when fully loaded, optimizing storage and transport efficiency.
Features a dual-spout structure differing from ordinary single-opening bags. The wide top skirt opening allows rapid bulk sand pouring without blockage or splashing. Dual discharge outlets at the bottom realize split discharging, allowing workers to control outflow speed and prevent material waste.
Lifting loops are sewn directly onto the side seams of the fabric instead of simply pasted on the surface. This integrated sewing method disperses lifting tension evenly across the whole bag body and lowers the probability of tearing when hoisting heavy sand.
Every stitching seam is fitted with two cotton strips to fill tiny gaps and block sand grains. The whole edge features blue overlock & binding reinforcement to prevent fraying. An extra layer of non-woven fabric is compounded inside to block fine sand permeation and buffer friction, prolonging the service cycle.

It features a multi-layer leak-proof system: every stitching seam is fitted with two cotton strips to block tiny sand grains, the edges are reinforced with blue overlock & binding, and an extra layer of non-woven fabric is compounded inside to prevent permeation.
Yes. The lifting loops are integrated and sewn directly onto the side seams of the fabric rather than pasted on the surface. This method disperses tension evenly and lowers the probability of tearing when hoisting heavy sand.
Yes, we support personalized modifications on loop styles, spout quantity, edge color, and leak-proof configurations according to your actual construction conditions.
These heavy-load FIBC bags are widely applied in sand mining, construction engineering, aggregate transportation, and building materials circulation industries worldwide.
