摘要：
A packaging construction being formed by multi-layer board material includes a middle layer, a first outer layer attached to the middle layer and a second outer layer attached to the middle layer. The packaging construction defines a bottom side, a top side, and a plurality of side panels joining the bottom side and the top side so as to form a closed structure. At least one edge is defined between adjacent side panels. The packaging construction is arranged so that the second outer layer has a lower bending stiffness according to ISO 5628 than the first outer layer such that the board is outwardly bendable only in a direction towards which the second layer faces, and in that the packaging construction is formed with at least one side panel being curved and/or at least one edge being rounded.
