Abstract
Cardboard packing case for transporting a load with a base and at least four walls, a film made from heat-shrinkable plastic material, and a horizontal added board for pressing down and holding the heat-shrinkable film flat on the inner face of the base of the case, the board having a median line parallel to two walls for longitudinal folding of the board into a tent shape, the median line having a ridge facing towards the top of the case, wherein the film is in the form of a rectangular curtain in a single piece emerging on either side of two opposite edges of the board parallel to the median folding line and extending from those edges over a length sufficient to cover over one another, such that the film envelopes the load and immobilizes it by heat shrinking of the film, and a process and device for producing such a packing case.
