2 Ton U-Panel FIBC Sand Bulk Bag | China Suppliers & Factory with Side Seam Loops & Dual Discharge Spouts
Detailed Description
Heavy-Load U-Panel Stability
Developed to cope with the harsh working environment of construction sites and sand stock yards, this heavy-load U-panel FIBC solves two major troubles of traditional sand bags: fine sand seepage and premature edge wear. U-shaped panel structure improves the overall stereoscopic stability of the bag body. When fully loaded with sand, the bag can stand upright naturally without bulging or serious distortion, which brings convenience for stacking storage and forklift transportation, greatly optimizing the layout efficiency of construction yards and material warehouses.
Dual-Spout Rapid Flow & Hoisting
The bag adopts a dual-spout structure that differs from ordinary single-opening ton bags. The wide top skirt opening allows bulk sand to be poured in rapidly without blockage or splashing during feeding. The dual discharge outlets at the bottom realize split discharging. Workers can control the outflow speed of sand arbitrarily according to construction progress, avoiding material accumulation and waste caused by one-time full discharging. Lifting loops are sewn onto the side seams of the fabric instead of simply pasted on the surface, the integrated sewing method disperses lifting tension evenly across the whole bag body and lowers the probability of tearing when hoisting heavy sand.
Multi-Layer Leak-Proof System
The multi-layer leak-proof reinforcement system is the core highlight of this sand FIBC. Every stitching seam is fitted with two cotton strips to fill the tiny gaps between stitching lines, which can block tiny sand grains from escaping out of the seams fundamentally. The whole edge is treated with blue overlock & binding reinforcement to prevent the woven fabric from fraying after long-term friction. An extra layer of non-woven fabric is compounded inside the bag, which not only further blocks fine sand permeation, but also buffers friction between sand and the PP woven base cloth, prolonging the service cycle of the bulk bag repeatedly.
Rigorous Testing & Customization
Made of virgin high-tenacity polypropylene woven fabric, every finished sand FIBC will undergo load-bearing pull test and leak inspection before delivery to guarantee stable quality for mass orders. Apart from fixed structural styles shown here, we support personalized modification on loop styles, spout quantity, edge color and leak-proof configurations according to clients’ actual construction conditions. This FIBC is widely applied in sand mining, construction engineering, aggregate transportation and building materials circulation industries worldwide.

Frequently Asked Questions
The FIBC uses a multi-layer leak-proof system where every seam is fitted with two cotton strips to block tiny stitching gaps. Additionally, an interior non-woven fabric layer buffers friction and further prevents microscopic sand grains from escaping.
The U-shaped panel structure significantly enhances stereoscopic stability. When fully loaded, the bag remains naturally upright without bulging or excessive distortion, allowing for safer, more organized stacking and forklift transport in job sites.
The wide top skirt opening enables rapid bulk sand filling without splashing or clogging. At the base, dual discharge outlets permit controlled, split discharging so operators can regulate flow according to site progress and avoid wasteful dumping.
The lifting loops are integrated directly into the side seams of the fabric rather than merely surface-attached. This integrated construction disperses tensile stress evenly throughout the body, dramatically reducing the risk of tearing under heavy loads.
Every batch manufactured from virgin high-tenacity polypropylene woven fabric undergoes rigorous load-bearing pull tests and thorough leakage inspections prior to dispatch to ensure dependable safety standards for mass industrial orders.
Yes. In addition to standard models, customizable options include lifting loop configurations, discharge spout count and dimensions, edge binding colors, and specialized leak-proof liner combinations to suit unique operational conditions.
