A method for creating an opening in a sheath, made of stretch film, that retains a goods stack arranged on a pallet. The pallet comprising an upper-side deck surface as support for the goods stack and lower-side support feet. The sheath engages under the support feet arranged in the region of the four outer edges of the pallet. At least one opening is in the sheath between two support feet . At least one opening is generated such that the sheath is first heated, the heated sheath is retracted from the pallet and then, still in the heated state, displaced upward. The upwardly displaced sheath is secured in its upwardly displaced position by cooling. The invention also relates to a shaping apparatus, and additionally to at least one heating device for carrying out the method.

A tray sealer including a sealing station comprising a tool upper part, a clamping frame and a tool lower part. The tool upper part may surround a dome-shaped die used for deforming a skinnable top film. First and second channels in the dome-shaped die and in the tool upper part, respectively, are connectable to one another. The tool upper part or the dome-shaped die may comprise at least a third channel communicating with a vacuum generator so as to generate a thermal air convection from the first channel to the third channel along a side of the top film facing the dome-shaped die.
