Flexible Pallet (Bulk Bag)

FIBC (Flexible Intermediate Bulk Container) is a large flexible packaging container made of polypropylene woven fabric, designed to carry bulk materials ranging from 500kg to 2000kg, such as chemicals, grains, and minerals. Its core functionality revolves around the unitized transportation concept, fundamentally transforming fragmented packaging models into integrated unit-load systems. By establishing standardized unitized containers, FIBC enables integrated lifting operations via cranes or forklifts, eliminating manual disassembly processes. For example, a truckload of cement traditionally requires hundreds of separate bags for manual handling, whereas FIBC systems accomplish full vehicle loading through single-lift operations, significantly improving efficiency.

Manufactured through polypropylene resin melting, filament drawing, fabric weaving, and sewing processes, FIBC maintains structural integrity under multiple times of rated load impacts during transit. Additional material modifications or structural enhancements enable specialized functions: moisture-proofing for grain storage to prevent mildew, anti-static liners for calcium carbide transportation to avoid explosions, and UV-resistant coatings for outdoor applications.

When empty, FIBCs can be compactly folded, reducing storage space. Reusable variants further enhance cost-effectiveness and environmental sustainability compared to single-use packaging. Serving as "flexible containers," FIBCs standardize bulk cargo handling across scenarios from port terminals to construction sites, resolving efficiency and cost challenges in loose material logistics through mechanized operations.

FIBC (Flexible Intermediate Bulk Container): The formal technical designation under international transportation regulations and quality certifications, systematically defining their flexible structure and intermediate-scale bulk handling characteristics.

Jumbo Bags: Derived from their massive and load-bearing capability, frequently used in maritime bulk cargo transport for commodities like ores and grains. The term "Jumbo" emphasizes their visually imposing design.

Space Bags: Highlights space-saving characteristics. Their collapsible design makes them prevalent in Southeast Asian export regions for optimal container space utilization during bulk cargo shipping.

Bulk Bags: A generic term in European and American markets, directly denoting their primary application in transporting unpackaged materials (e.g., chemical powders, cereals), emphasizing functional purpose over structural specifics.

Ton Bags: Explicitly references the standardized weight capacity, commonly used in technical documentation and ISO standards to specify industrial-grade load specifications.

The core distinctions between FIBCs and ordinary woven bags lie in load-bearing capacity, structural design, protective performance, and application scenarios. FIBCs typically have a load capacity range of 0.5–2 tons, with a structure primarily composed of outer polypropylene (PP) woven fabric. High-end variants incorporate inner liners such as polyethylene (PE) film or aluminum-plastic composite materials to enhance sealing properties, alongside integrated lifting loops and reinforced circular straps for compatibility with forklifts or cranes. In contrast, ordinary woven bags have a maximum load capacity of 50 kilograms, relying mainly on single-layer PP woven fabric strength, though some products may incorporate inner liners (e.g., HDPE, EVA) or surface coatings (PE, PVC) for basic moisture resistance.

Regarding protective performance, FIBCs achieve specialized safeguards through UV-resistant masterbatch additives, aluminum-plastic composite layers, or conductive thread weaving techniques. Ordinary woven bags, however, are constrained by liner integrity and process costs, offering only basic protective capabilities.

In application scenarios, FIBCs are designed for mechanized bulk material transport (e.g., mineral ores, lithium battery materials, hazardous chemicals), with high customization levels (e.g., internal tension straps for deformation resistance, aluminum foil oxygen barrier for freshness preservation). Ordinary woven bags, while suitable for small-batch chemical additives or construction materials, are incompatible with highly corrosive or precision-sensitive materials due to structural strength and sealing limitations.

The design philosophies diverge significantly: FIBCs prioritize high load capacity, robust protection, and customizability, whereas ordinary woven bags emphasize cost efficiency, lightweight design, and incremental functional upgrades.
