In terms of the packaging, you need to make sure that it can withstand the specific stresses during the flight. As a guide, vertical impacts of three times the weight and vertical impacts of 1.5 times the weight of the parcel need to able to be absorbed. The packaging should also be stackable.
During loading in the hold, the goods may be stacked on top of one another and should be able to withstand the pressure from above. Depending on the type of shipping selected, packaging always includes, for example, appropriate outer packaging, a pallet, appropriate inner packaging as well as secure closure, if applicable, edge protection, lashing straps and bubble wrap.
