What is UN approved packaging?
UN approved packaging is a type of box or liner that has been produced, tested, and certified by the United Nations in order to safely transport dangerous materials – solid or liquid. UN boxes and UN certified packaging is developed for its durability, stability and water absorption. Doing so assures its efficacy in safely transporting high-risk goods, including infectious substances, flammable items and liquids, chemicals, toxic substances, pesticides and more.
Find the right UN approved packaging for your goods
Many types of containers, materials, and packaging groups fall within this line of products. Challenge Packaging specialises in the following:
UN-approved boxes
- Boxes approved for meeting UN standards to carry hazardous goods by rail, air, land, and sea.
- These boxes are ideal for solid or packaged dangerous goods that require strong outer protection.
- 4G boxes are designed to hold inner packaging like bottles or tins.
- 4GV boxes are designed for a wider variety of inner packaging types.
UN-certified liners
- Polythene bags that are certified to carry dangerous items, even without using UN-approved boxes.
- The box or liner you use will depend on the amount of goods classified by their 4G or 4GV rating.
- Suitable for transporting dangerous goods without a UN-approved box.
- Lightweight, space-saving, and versatile.
