Key Indicators for Determining When to Replace FIBC Bags

Conclusion: Replacing FIBC Bags before problems occur is critical

FIBC (Flexible Intermediate Bulk Container) bags are essential materials that directly affect not only cargo safety but also worker safety.
Continuing to use deteriorated bags can lead to bag rupture, load collapse, and serious accidents.
For this reason, regular inspection and timely replacement are indispensable.

Before anything else, once you understand the signs of deterioration, the next crucial step is choosing a reliable supplier that can ensure safety and consistent quality.

Main Signs That Indicate It Is Time to Replace FIBC Bags
1. Long-Term Storage Under Direct Sunlight

Ultraviolet (UV) exposure is the primary cause of FIBC bag deterioration.

Warning signs include:

Fabric becoming stiff or rough to the touch

Material tearing easily even under light force

2. Fraying or Wear of Lifting Loops

Lifting loops are the most critical load-bearing components of an FIBC bag.

Replacement should be considered if:

Fraying or fuzzing is visible

Areas in contact with hooks or lifting devices show abrasion

3. Deterioration at the Lifting Loop Stitching

Stitched areas are subject to concentrated stress and tend to degrade faster.

Inspection points:

Loose or broken stitching threads

Tearing or wear of the surrounding fabric

4. Wear or Thinning of the Bag Body

Due to load weight and friction with floors or pallets, the fabric gradually wears down.
Even minor damage can compromise safety—early replacement is the safest approach.
