These bags are selected and produced according to international hazardous material transport regulations, including ADR requirements for road transport.
In this type of packaging, bag strength alone is not enough. Material type, risk level, transport method, storage conditions, and certification information must also be correctly specified on the bag.
UN Big Bags are classified according to body structure, lamination, and the use of an internal liner. The right type depends on material sensitivity, additional protection needs, and transport conditions.
Hazardous materials are classified into packaging groups based on risk level. This grouping defines the level of hazard for which the packaging must be designed and approved.
For high-risk materials. Recommended maximum volume: 1.5 m³
For medium-risk materials. Recommended maximum volume: 3 m³
For low-risk materials. Recommended maximum volume: 3 m³
— Quality
Before final approval, a UN Big Bag must pass defined quality control tests. These tests evaluate bag performance under transport, drop, pressure, storage, and potential damage conditions.
01
Checks body resistance against tearing and damage propagation
02
Evaluates bag performance against impact caused by falling
03
Checks stability and resistance when the bag falls or rotates
04
Evaluates shape retention and bag safety under operational conditions
05
Assesses bag resistance under load and warehouse stacking
04
Checks bag tolerance against pressure and severe stress
UN Big Bags are used for transporting and packaging materials where compliance, risk control, and handling safety are essential.
