Abstract:
1. A method for manufacturing a package out of foil, the method comprising: moving a foil section to a position between first and second parts of a thermoforming station such that the foil section is moved with respect to both the first and second parts, the thermoforming station further including a heating device mounted on the first part such that the heating device is positioned between the first and second parts, and a mould mounted on the second part; heating the foil section using the heating device; generating negative pressure relative to ambient pressure on two sides of the foil section during a time interval during the heating step; and forming a cavity in the heated foil section using the mould, wherein the cavity is configured to subsequently receive goods after being formed; wherein the generating step comprises generating a larger negative pressure on one side of the foil section compared to the other side of the foil section, and the heating step comprises heating the foil section from the one side.
