Abstract

The present invention relates to inductor coils for induction welding of packaging materials. An inductor coil for induction welding of packaging material having at least one layer of metal foil is disclosed. The inductor coil is configured to induce an alternating current in the metal foil to inductively heat the packaging material. The inductor coil includes a base material, a top material bonded to the base material to form an irreversibly bonded interface comprising a mixture of the base material and the top material. Also disclosed is an induction sealing device comprising at least one inductor coil, and a method of manufacturing an inductor coil for induction welding packaging material.

Description

technical field [0001] The invention relates to an inductor coil for induction welding of packaging materials having at least one metal foil. The invention also relates to an induction sealing device comprising such an inductor coil, a sealing machine comprising such an induction sealing device, and a related method of manufacturing an inductor coil for induction welding of packaging material having at least one layer of metal foil. Background technique [0002] Welding of laminated packaging materials by induction heating is used in the packaging industry. An example of such a laminate is a paper carrier layer, aluminum foil and a thermoplastic coating along the interior and exterior surfaces of the laminate. The technique of induction welding is based on the fact that a magnetic field generated by an alternating current around a conductor can induce a current (depending on the resistance of the material) in adjacent conductive materials, causing the material to heat up. ...
