Abstract
A method and apparatus for induction sealing of a packaging material which includes a layer of aluminum foil. The apparatus includes an inductor with two parallel slightly spaced apart conductors which are disposed in an electrically insulated carrier portion. The conductors are connected to one another and to a high frequency current source by two transverse conductors. The transverse conductors are placed in the upper surface of the inductor and coincide with the outer defining lines of a flat-laid tube of packaging material.
