Abstract

An inductor for induction (100) welding of a packaging material (101) having at least one layer of metal foil is disclosed. The inductor (100) comprises a welding surface (102) configured to be arranged opposite the packaging material (101) for heating thereof, and at least one spacing element (103, 103', 103'', 103''') arranged to protrude from the welding surface (102) in a first direction (104) towards the packaging material (101), when the packaging material (101) is arranged opposite the welding surface (102), whereupon the least one spacing element (103, 103', 103'', 103''') separates the packaging material (101) from the welding surface (102) by an off-set distance (105). A sealing machine for sealing a packaging material (101) and a method of welding a packaging material (101) is also disclosed.
