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.

[ What is claimed is:] [1.]1. Cardboard packing case for transporting a load, comprising a base and at least four side walls, said at least four side walls comprising two first opposite walls and two second opposite 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 an inner face of the base of the case, said board comprising a substantially median line for provisional longitudinal folding of the board into a tent shape, said median line being substantially parallel to the two second walls,wherein said median line comprises a ridge facing towards a top of the case,and wherein the film is in the form of a rectangular curtain in a single piece emerging on either side of two opposite facing edges of said board parallel to the median folding line and extending from said edges over a length which is sufficient to cover over one another, whereby the film is suitable for enveloping said load and immobilizing it by means of heat-shrinking of the film.
