Product Overview U-type FIBC is a high-stability integrated forming bulk bag featured with a unique U-shaped integral bag body structure. Different from traditional four-panel spliced ton bags, it adopts one-piece U-shaped weaving molding with seamless side corners and integrated lifting webbings seamlessly connected with the bag body. With optional aluminum foil inner film or PE inner lining, it is suitable for medium and heavy-load bulk materials, featuring better stereoscopic shape, stronger bearing uniformity and higher stacking stability. It is widely used for packaging granular, powdery and granular bulk materials such as chemicals, minerals, grain, fertilizer and building materials, being a universal and high-cost-performance industrial packaging solution. Industry Pain Points Solved – Bulky shape & poor stereoscopic effect: Traditional four-panel spliced ton bags are prone to bulging, irregular shape and corner expansion after filling, resulting in untidy stacking, space waste and easy cargo extrusion during container transportation. – Stress concentration & easy cracking at seams: Spliced bag bodies have multiple stitching seams. Corners and splicing positions bear concentrated force during lifting and stacking, which are easy to crack and leak powder after long-term extrusion and friction, causing cargo loss. – Unstable stacking & safety hazards: Irregular filled bag bodies lead to uneven stress during high stacking, easily causing tilting, sliding and collapsing, bringing hidden dangers to warehouse storage and logistics safety. – Poor sealing & easy residue: Traditional right-angle dead corners of spliced bags are prone to material accumulation and residue, resulting in incomplete discharging and reduced material utilization rate; gaps at seams also cause dust and moisture infiltration. Core Selling Points – Integrated U-shaped molding, neat stereoscopic shape: One-piece U-shaped integral weaving process eliminates side splicing seams. The bag body is upright and regular after filling without bulging and deformation, ensuring standardized stacking and maximizing container loading space. – Uniform force bearing & anti-cracking durability: No splicing weak points on the main body. The overall stress is uniform during lifting and extrusion, effectively avoiding seam cracking and local damage. It greatly improves bag durability and reduces cargo leakage risks. – High stacking stability & improved safety: The smooth and upright U-shaped structure ensures flat stress on the top and bottom of the bag. It supports high-layer stable stacking, effectively preventing cargo sliding and collapsing, and improving overall warehouse and transportation safety. – Smooth discharging & zero material residue: Arc transition corners of the U-shaped design avoid dead corners for material accumulation. Powdery and granular materials slide down smoothly during discharging, reducing material waste and improving raw material utilization rate. – Optional high-barrier protection: Can be equipped with integrated aluminum foil inner film or PE inner lining, realizing moisture-proof, oxygen-proof, dust-proof and light-shielding functions, meeting the packaging needs of common materials and high-value sensitive materials. – Strong compatibility & cost-effective: Supports customized load capacity, lifting loops, inlet and outlet methods. Compatible with automatic filling machines, forklifts and crane lifting, suitable for most industrial bulk packaging and logistics scenarios with high comprehensive cost performance. – Reinforced overall structure: The integrated U-shaped structure enhances the overall toughness and tensile strength of the bag body, resisting long-distance transportation friction, repeated stacking and heavy-load lifting, with long service life.
