Induction sealing system

An induction sealing system for heat sealing packaging material for producing sealed packages of pourable food products, said sealing system comprising:

• a sealing jaw consisting of:
• at least one inductor device having at least one active surface facing said packaging material when in use;
• an insert comprising magnetic flux-concentrating material;
• a supporting body comprising heat-conducting material, wherein said at least one inductor device and said insert are housed within said supporting body;
• and
• a plastic member securing the insert and the at least one inductor device to the supporting body, the plastic member comprising an interactive surface configured to press against said packaging material when in use and a ridge protruding outward from the interactive surface of the plastic member and extending along a length of the sealing jaw;
• and
• a counter-jaw comprising at least one pressure pad made of elastomeric material, said at least one pressure pad configured to provide a counter pressure to the sealing jaw, wherein said at least one pressure pad has an arched convex contact area, wherein the arched convex contact area comprises ends and a middle portion between the ends, the middle portion closer to the sealing jaw than to the ends, wherein an apex of the arched convex contact area is aligned with the ridge of the plastic member of the sealing jaw;
• wherein said at least one inductor device comprises a first inductor device having a first active surface and a second inductor device having a second active surface;
• and
• wherein said ridge of said plastic member is positioned between and is spaced from the first and second active surfaces.
