At Global-Pak Inc., we are committed to providing the highest quality Flexible Intermediate Bulk Containers (FIBCs) to our customers. With the recent updates to ISO 21898:2024, it’s important to understand how these changes impact the manufacturing, safety, and stacking requirements of bulk bags. Here’s what you need to know about the latest revisions to the standard.

Key Changes in ISO 21898:2024

1. Material Compliance & Strength

The revised standard mandates that all FIBCs must be manufactured using materials with documented specifications and a statement of conformity for each production batch. Additionally, load-bearing materials must retain at least 50% of their original tensile strength after testing, ensuring better long-term durability.

2. Design & Filling Height Guidelines

To enhance stability and reduce handling risks, ISO 21898:2024 suggests that the filling height of an FIBC should not exceed twice the shortest base dimension. This update ensures bags remain stable and safe during transport and stacking.

3. Use of Recycled Materials

In a move toward sustainability, the standard now allows recycled mono-materials (consisting of at least 95% of the same polymer) to be used in bag construction. However, these materials must meet the same performance criteria as virgin materials, ensuring quality and reliability.

Updated Stacking Requirements

One of the most critical updates to ISO 21898:2024 is the reinforcement of stacking and compression testing standards:

• Compression Testing: All FIBCs must undergo a stacking test where they are loaded with a specific weight for a set period. Bags must not rupture or lose contents, ensuring safety in storage and transport. While minor discharge from stitch holes is acceptable, it must cease once the bag is lifted.

• Stacking Labeling Requirement: To improve safety, all FIBCs must now be clearly labeled with their maximum stacking capacity. This ensures users can easily determine how many bags can be safely stacked, reducing the risk of accidents.

What This Means for Global-Pak Customers

At Global-Pak Inc., we take compliance seriously. Our FIBCs are designed and tested to meet or exceed ISO 21898:2024 standards. These updates further emphasize the need for rigorous quality control, clear labeling, and sustainable material usage in FIBC production.

For our customers, these revisions mean safer and more reliable bulk bags that comply with the latest industry regulations. If you have any questions about how these changes impact your operations or need guidance in selecting the right FIBC, our team is here to help.
