A device for shaping a film of heat-retractable plastics material in the zone of the lateral spaces of a pallet-less multi-layer load having a layer of reduced width, said spaces for gripping purposes being defined by right-angled dihedrons, comprises mobile shaping elements intended to be applied against the film of plastics material which is still soft covering the faces of each dihedron defining a space for gripping. Each shaping element is constituted by a bar and means are provided to displace each shaper bar in the direction of the edge of the dihedron, to engage said bar in the angle of the dihedron between the layer of reduced width and the normal layer of the load located beneath this reduced layer. Each shaper bar is fast with one or more elements accelerating cooling of the plastics material. The or each cooling element is adapted to be applied against the vertical and horizontal faces of the dihedron defining the space for gripping, at the same time as the shaper bar is engaged in the angle of the dihedron.
