Abstract
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.
