4 Loop FIBC Bag

Details

The 4 Loop FIBC Bag is one of the most common types of flexible bulk containers. It derives its name from the four high-strength lifting straps it features.
Construction
The bag is primarily made of polypropylene (PP) woven fabric, with some models incorporating an inner layer of PE film or breathable non-woven fabric based on specific requirements.
Design & Functionality
The entire bag is flexible and foldable, making it ideal for the containerized transportation and storage of loose materials, including granular, powdered, and block-form substances.
Key Advantage
Its core strength lies in the balanced force distribution design of the four lifting straps, which ensures compatibility with mainstream loading and unloading equipment such as forklifts and cranes.

Performance Advantages

Balanced Load-Bearing and High Safety

After undergoing force testing, the 1000 kg-capacity 4 Loop FIBC Bag demonstrates a breaking tension of ≥4000 N per sling. When all four slings are under load simultaneously, the top of the bag experiences a load deviation of ≤5%, effectively preventing deformation or rupture caused by excessive localized stress.

Flexibility and Portability

In an empty state, the bag can be folded to 1/20th of its original volume. A single empty bag weighs only 1.8–3.5 kg (depending on load capacity specifications). For example:

The empty bag for a 1000 kg specification weighs approximately 2.2 kg.

The empty bag for a 1500 kg specification weighs approximately 2.8 kg.

Compared to rigid packaging, it reduces storage space requirements by over 90% during empty-bag transportation.

Usage Value

Usage Value: Why Choose the 4 Loop FIBC Bag

Enhanced Operational Efficiency

The four lifting straps are compatible with mainstream equipment such as forklifts and cranes, enabling a single operator to complete the hooking process. Loading and unloading a single bag takes approximately 2–4 minutes-50% faster than traditional single-sling bulk bags, which require two workers to balance the load.

Ensured Transportation Safety

The balanced four-sling design minimizes the risk of localized stress damage. The bag's damage rate has dropped from 7% (for conventional bulk bags) to below 1.2%. Customizable features for different materials prevent deterioration, spillage, or safety incidents, reducing return rates caused by packaging defects.
