ABSTRACT:
A method and a device for manufacturing packages are provided. The method comprises providing a tubular first package part of a sheet of thermoplastic coated packaging material including at least one layer of an induction heatable material. The first package part has a sealed first joint between two mutually opposing edge sections of the sheet. The method further comprises joining together the first package part and a second package part by a second joint, the first and the second joint intersecting each other. The method further comprises arranging induction heating means including at least two conductors extending along each other, so that the conductors extend along the second joint and sealing the second joint by feeding an inducing current through the induction heating means. The inducing current is conducted by the conductors along the second joint in opposite directions in said at least two conductors.
