What are Fibreboard Boxes used for?

Fibreboard is a commonly used packaging product in hazardous packaging and 4GV Fibreboard Boxes are UN approved for packing groups I, II & III.

What is a 4G Fibreboard Box?

A 4G Fibreboard box is a type of packaging that is made from recycled paper and cardboard. It is often used for packaging products such as food, chemicals, and electronics. The box is sturdy and can be used for shipping or storage.

4G UN boxes are UN packaging boxes which include an inner package within a single outer box. The outer package has the UN packaging code, and this stays valid providing the box is assembled with the same method as in testing.

How are Fibreboard Boxes Made?

Fibreboard boxes are crafted by bonding a series of corrugated sheets together to create a triple-layered wall. This construction method results in an airtight and robust box. The sheets are precisely cut, scored, and glued in a specific pattern to ensure the box’s strength and durability. Additional reinforcement with tape or staples securely seals the box.
