But they only take a maximum of 100x60x40-cm-boxes, and that's what makes this folding. He holds also the critical gross limit, so the external dimensions.
However, caution is advised if you really want to take advantage of 40 kg even close: For the 2-wave cardboard is ultimately too weak, and a 3-wave there is not to my knowledge.
I have so helped me: the packaging carton with which this folding is supplied, you can use suitable for internal reinforcement, then vigorously use chips, and at the end of the construct as an Egyptian mummy with the cheap scotch tape; wrap psc = 1.
No 5 stars, because the solution is cumbersome. More than 3 stars because there is probably not a viable alternative for the described type of mission effectively.
