The 4 Loops Jumbo Bag, also known as a 4-loop FIBC (Flexible Intermediate Bulk Container), is a large flexible storage and transportation solution designed for handling bulk materials. Characterized by its four reinforced lifting loops, this bag is engineered to facilitate efficient loading, unloading, and stacking via mechanical equipment such as forklifts or cranes. Constructed from high-strength woven polypropylene fabric, it balances durability and flexibility, making it suitable for a wide range of granular, powdery, or pelletized materials. Its design ensures stable lifting and even weight distribution, reducing the risk of tilting or spillage during handling. Widely adopted in industrial, agricultural, and logistics sectors, it offers a cost-effective alternative to rigid containers for bulk material management.

The bag is equipped with 4 symmetrically positioned lifting loops made from thickened polypropylene webbing (30 mm in width). Each loop features a breaking strength of 2500 kg, ensuring safe lifting of full loads. The symmetrical design distributes weight evenly across all loops, minimizing stress on individual components and reducing the risk of tearing during transportation. This structure allows compatibility with standard forklift tines and crane hooks, enhancing operational efficiency.
The main body is crafted from woven polypropylene fabric with a basis weight of 150–220 g/m², depending on the model. The fabric exhibits a tensile strength of minimum 14 kN/m in warp direction and 12 kN/m in weft direction, providing resistance to stretching under heavy loads. Optional treatments include UV stabilization (adding 0.3–0.8% UV inhibitors) for outdoor use, extending service life to 6–9 months under direct sunlight, and anti-static coating for environments with electrostatic sensitivity.
Designed with a Safe Working Load (SWL) ranging from 1000 kg to 3000 kg, the bag features a standard safety factor of 5:1 (up to 6:1 for heavy-duty models), meaning it can withstand a maximum breaking load of 5000–18000 kg. This makes it suitable for both light and heavy bulk materials, from agricultural grains to construction aggregates.
Available in various configurations to meet specific needs:
• Open top with duffle closure for easy filling
• Spout top for controlled loading
• Flat bottom for stable stacking
• Baffled design (optional) to maintain shape when filled, allowing vertical stacking of 4–6 units
• PE liner (optional, thickness 50–100 microns) for moisture or dust protection of sensitive materials
The 4 Loops Jumbo Bag is widely used across industries:
• Agriculture: Transporting and storing grains, pulses, seeds, and animal feed. The woven fabric allows breathability, preventing moisture buildup in organic materials.
• Construction: Handling sand, gravel, cement, and dry mortar. Its high load capacity suits large-scale construction site requirements.
• Mining: Carrying mineral ores, coal, and metal concentrates. The durable fabric resists abrasion from sharp particles.
• Chemicals: Packaging non-hazardous granular or powdered chemicals, such as fertilizers, detergents, and plastic resins. Optional liners provide additional protection against contamination.
• Waste Management: Collecting and transporting recyclable materials (e.g., plastic bottles, paper) and industrial waste, supporting efficient waste logistics.
Standard sizes range from 80x80x120 cm to 120x120x200 cm, with a volume of 500–2800 liters. Custom dimensions are available based on specific material volume requirements.
Under normal conditions and with proper handling, it can be reused 2–4 times. Reusability depends on material type (sharp materials may reduce lifespan) and post-use inspection for damage.
Yes, food-grade versions are available, constructed from FDA-compliant polypropylene without harmful additives. These meet food contact standards (e.g., EU 10/2011) and are suitable for grains, sugar, and food additives.
It operates safely within a temperature range of -40°C to 80°C. Exposure to temperatures exceeding 80°C for extended periods may reduce fabric strength.
Store in a dry, well-ventilated area away from direct sunlight and sharp objects. Avoid folding under heavy loads to prevent crease damage. For long-term storage (over 6 months), UV-protected covers are recommended.
