Method for sealing a tear-off foil onto a packaging element, comprising the following steps:

• a sealing step including the steps of:
• transporting the packaging element in a conveyor device,
• moving the packaging element by a sealing stroke crosswise to a direction of transport towards a stamp tool carrying punched-out foil,
• moving the stamp tool carrying punched-out foil towards the packaging element by a feed stroke executed counter to the sealing stroke, and
• pressing the packaging element during the crosswise sealing stroke against the foil to seal the foil and the packaging element together under the effect of heat,
• a heating step preceding the sealing step which includes the step of heating the packaging element by a non-contact arrangement, to at least a temperature required for subsequent sealing, and
• a joining step after the sealing step which includes the step of joining the packaging element to another packaging part to form a complete packaging.
