Abstract
The invention relates to a sealing device (100) and a method for heat sealing packaging material for producing sealed packages. The invention also relates to a filling machine. The sealing device (100) comprises a first jaw (110) comprising an electromagnet (112), and a second jaw (120) comprising a magnetic element (122). The second jaw (120) is arranged opposite to the first jaw (110) to form a gap adapted to receive the packaging material, such that the first jaw (110) and the second jaw (120) are attracted to each other upon actuation of the electromagnet (112) to close the gap and clamp the packaging material between the first jaw (110) and the second jaw (120).
