Abstract
The present invention relates to a packing case comprising a box, a heat-retractable plastic and at least one lid, for storing, handling and transporting a charge. In the said case, the heat-retractable plastic (2, 22) in sheet form is bonded at one or more of its edges (32, 322) to the outer surface of a wall (3) of the said box, in the vicinity of the side of the said wall, and extends, on the outside, from the said edge (32, 322) to the side of the said wall and then inside the box, opposite the inner surface of the said wall, moving away from the latter towards the charge which is to be packed. In the said case, the charge is held down against the bottom by means of the heat-retractable plastic along an overlapping zone.
