UN Approved FIBC Bags


UN-approved FIBC bags, also known as UN bags, are essential for safely transporting hazardous materials. To ensure safety and compliance, these bags undergo a series of rigorous tests specified by the United Nations, including drop, topple, and lift tests. These tests guarantee that the bags can withstand the stresses of transportation without compromising their integrity.

There are four main types of UN bags, classified by their construction:

1. 13H1: These bags are non-coated and do not have an inner liner. They are suitable for materials that do not require additional protection from moisture or contamination.
2. 13H2: Similar to 13H1 bags, these are non-coated but include an inner liner, providing an extra layer of protection for the contents.
3. 13H3: These bags are coated but do not have an inner liner. The coating helps to protect the contents from external moisture and contamination.
4. 13H4: These are the most protective type, featuring both a coating and an inner liner. This dual protection makes them suitable for highly sensitive or hazardous materials that require stringent safety measures.

The classification of these bags also includes symbols X, Y, and Z, which indicate the level of danger the bag can handle. Symbol X denotes the highest level of danger, capable of containing the most hazardous materials. Symbol Y indicates a medium danger level, suitable for moderately hazardous materials. Symbol Z represents the lowest danger level, appropriate for less hazardous materials.

Each type of bag and danger level classification ensures that the appropriate bag is used for the specific material being transported, minimizing the risk of accidents and ensuring compliance with international safety standards. These classifications and rigorous testing protocols underscore the importance of UN-approved FIBC bags in the safe and efficient transport of hazardous goods.
