  • the containers must withstand shocks and high loads.
  • the known containers therefore have the problem of being very massive and heavy and are therefore expensive to manipulate. Since every kilo counts in air traffic in order to achieve fuel savings and to be able to transport more freight or passengers, the great weight of known containers is a huge disadvantage and a cost-increasing factor.
  • the storage of the unused and the transport unloaded containers by the fixed predetermined form space intensive and increases here, too, the highly competitive prices in air traffic.

  • the structure and the materials used allow for easy assembly of the container.
  • the container is given a higher rigidity with a lower weight, which makes it possible to achieve a total weight of only 40 kg, which is many times less than the weight of conventional air freight containers. Furthermore, the materials used can easily be checked at security checks without extra effort and therefore save time in manipulation and transport at the airport.
