An induction sealing device for induction welding of a packaging material is disclosed. In some embodiments, the induction sealing device comprises an inductor coil configured to induce an alternating current in a metal foil of the packaging material for inductive heating thereof. The induction sealing device can further comprise a magnetic insert encapsulating the inductor coil apart from an outer portion of the inductor coil, and the outer portion can be arranged towards the packaging material to be sealed. In some embodiments, the magnetic insert is configured to interact with the packaging material to be sealed via at least one interactive surface. In some embodiments, the induction sealing device comprises a connection unit. The connection unit can comprise a parallel connection configured to connect to the inductor coil and to an AC power source. A corresponding method of manufacturing an induction sealing device is also disclosed.
