DeutschSealing systems of UN-certified boxes
Before shipping dangerous goods, you better make sure that your UN-certified boxes are packed and sealed in the right way. A safe and effective sealing is fundamental to ship in compliance with the regulations. During the certification test, certain systems of sealing and specific types of tapes will be used: they must be the same that will be used in your daily activities of packing and preparation of shipments of dangerous goods. The same box can be UN-certified with different sealing systems. In order to use the right sealing system, you must check which was the system and the kind of tape used during certification tests. Here below you’ll find a sum-up of the main sealing systems used during UN-certification tests of our 4G and 4GV boxes, more details are to be found in the test report of the UN-certified packaging.
