What Are the 5 Most Common Types of FIBC Lift Loops?

Flexible Intermediate Bulk Containers (FIBC), commonly known as bulk bags, are designed to handle, store and transporting large quantities of dry flowable materials. These bags feature integral lifting loops for easy handling. Usually the lifting loops are made from high tensile strength woven fabric. The 5 most common seen lifting loops found on FIBC bags include:

1. Cross Corner Loop:

Description: These loops are attached to the corners of the bag, typically resemble an arch shape and form a stable lifting point. Cross corner loops are most likely seen in circular type bulk bags. Industry standard common size of cross corner loop size is 3 inches width and 10 inches height.

Advantages: Provide a strong and secure lifting point, suitable for lifting heavy loads.

2. Side-Seam Loop:

Description: It's also called corner seam lift loop in some specific region. These loops are most likely seen on U-panel and 4-panel types bulk bags, the loops are sewn or attached along the side seams of the bag, the loop resemble a tear drop shape above the top base panel of the bags. Industry standard common size of cross corner loop size is 2 inches width and 10 inches height.

Advantages: Offer an alternative lifting point. Extremely strong and durable in combination of side-seam loop and U-panel body type.

3&4. Single Loop, Double-loop

Description: As the name indicates, the bag loop is formed by the extension of the bag body fabric, forming one loop per bag, or two loops per bag, typically located at the top or at each side of the bag. Both single loop type and double-loop type are widely considered as being more cost-effective in all listed construction styles. Commonly used in Europe and less commonly used in America. Most commonly constructed with circular bag body structure. 

Advantages: Simple and cost-effective, suitable for lighter loads or when a single lifting point is sufficient.

5. Double Stevedore Loop:

Description: These are larger and additional loops, often designed for use with slings or other lifting devices such as a crane or hook system. They may be found on both sides of the bag. Generally stevedore loop is designed for single point lifting and lowering in handling processing. 

Advantages: Provide additional strength and stability for lifting heavy or awkward loads.

It's important to note that the specific type of lifting loop chosen depends on the intended application, the weight of the material being carried, and the lifting equipment available. Manufacturers often offer a variety of loop options to suit different needs. Additionally, custom loop configurations can be designed to meet specific requirements.

When selecting an FIBC bag with lifting loops, it's crucial to ensure that the loops are strong enough to support the weight of the material being carried and that they are securely attached to the bag. Proper handling and maintenance of the bags, including regular inspections for wear and tear, can help extend their lifespan and ensure safe operation.
