The 4-panel Open Top FIBC (Flexible Intermediate Bulk Container) Bag is a versatile bulk packaging solution designed for storing and transporting granular, powdered, or pelletized materials. Its structure consists of four separate woven fabric panels stitched together to form a rectangular or square shape, offering enhanced structural stability compared to simpler designs. The open top design facilitates easy filling, making it suitable for high-volume loading operations. Constructed from durable woven polypropylene, this FIBC bag balances strength and flexibility, catering to diverse industrial needs. It is widely used in sectors requiring efficient bulk material handling, providing a cost-effective and space-saving alternative to rigid containers.

The bag is composed of four individual woven panels (front, back, and two sides) joined by reinforced vertical seams. This design distributes stress evenly across the panels, increasing overall tensile strength. Each panel is crafted with interlocking polypropylene threads, enhancing resistance to tearing during filling and transportation. The 4-panel structure maintains a consistent shape when filled, allowing stable stacking (up to 5 units high) in warehouses or shipping containers.
The open top features a 30–50 cm wide opening with a reinforced hem to prevent fraying. It can be equipped with optional closure mechanisms such as a drawstring, toggle, or hook-and-loop fastener for partial sealing. This design simplifies filling via conveyor belts, chutes, or manual loading, reducing operational time. The open top also allows easy visual inspection of contents without full unpacking.
Made from woven polypropylene fabric with a basis weight of 160–210 g/m², the bag offers a tensile strength of 15 kN/m in warp direction and 13 kN/m in weft direction. Optional treatments include UV stabilization (with 0.5% UV inhibitors) for outdoor use, extending service life to 8–12 months under direct sunlight, and anti-static coating for environments with electrostatic hazards.
The bag has a Safe Working Load (SWL) ranging from 800 kg to 2500 kg with a standard safety factor of 5:1 (breaking load 4000–12500 kg). Heavy-duty models offer a 6:1 safety factor for higher weight requirements. It includes 4 lifting loops positioned at the top corners, each with a breaking strength of 2000 kg, ensuring balanced lifting by forklifts or cranes.
• PE liner (thickness 40–80 microns) for moisture-sensitive materials
• Reinforced bottom panel for extra durability during ground placement
• Printed labeling (up to 4 colors) for product identification and handling instructions
The 4-panel Open Top FIBC Bag is utilized across multiple industries:
• Agriculture: Storing and transporting grains, corn, soybeans, and animal feed. The woven fabric’s breathability prevents mold growth in organic products.
• Construction: Handling sand, cement, lime, and aggregate materials. Its large capacity reduces the number of trips needed for on-site transportation.
• Chemicals: Packaging non-hazardous powders such as fertilizers, industrial salts, and detergent granules. Optional liners protect contents from contamination.
• Food Processing: Suitable for food-grade materials like sugar, flour, and rice when made with FDA-approved polypropylene and food-safe stitching.
• Recycling: Collecting plastic pellets, paper scraps, and metal shavings, facilitating efficient recycling logistics.
Typical dimensions range from 75x75x100 cm to 110x110x180 cm, with a volume of 420–2178 liters. Custom sizes are available to match specific material volume needs.
Yes, it can be reused 2–3 times with proper inspection. Sharp materials (e.g., gravel) may reduce reusability, while non-abrasive materials (e.g., grains) allow more cycles.
When combined with a waterproof PE liner and UV stabilization, it can be stored outdoors for up to 3 months without significant material degradation. Extended exposure to rain is not recommended.
