UN bags can be divided into four major types, which we can supply to you:
UN bags have some limitations regarding their design.
UN bags must not be higher than twice the shortest side. They cannot have a larger volume than 3.0m3
The big bag cannot have an open top or a simple flap closure.
UN bags are not repairable and can be used only one time.
Top lift test
The big bag is loaded with six times its maximum gross mass and kept under this weight for 5 minutes. The big bag must not have any damage from this.
Stacking test
The big bag is loaded to its maximum allowable gross weight. Than 1.8 times the maximum stacking weight is loaded on top of the test bag for 24 hours. The big bag passes the test if there is no deterioration of the body or loss of content.
Drop test
The big bag is loaded with its maximum permissible gross mass and dropped from a) 1.2m if packaging group II and b) 0.8m if packaging group III. The UN bag shall not have loss of content.
Tear test
A 10cm hole is cut with a knife into a fully loaded UN bag. Then the double of the maximum gross load is applied to the UN bag for 5 minutes. The UN big bag is then lifted for 5 minutes. The UN bag passes if the hole does not increase by more than 25%.
Topple test
The UN bag is toppled from a) 1.2m height if packaging group II and b) 0.8m height if packaging group III. The bag shall not have loss of material.
Righting test
