A sealing member comprising a sealing section configured to interact with a sealing band of a tube of packaging material in a sealing stage, and a package volume controlling section configured to interact with a first area next to the sealing band of said tube of packaging material in the sealing stage, wherein said package volume controlling section is provided with a socket for holding an insert.

Sealing member comprising a package volume controlling section

The present invention relates to an induction sealing device for heat sealing of packaging material. The sealing device comprises a conductor partly encapsulated in a supporting body for cooperation with the packaging material during sealing. The coil conductor has a reduced cross sectional area at at least one position along the coil conductor so as to concentrate the magnetic flux induced by the coil conductor at the at least one position. The invention also relates to a method of heat sealing a packaging material using the induction sealing device.

Induction sealing device and method of sealing a packaging material using said induction sealing device

Disclosed embodiments relate to an induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products. In some embodiments, the sealing device includes: an inductor device which interacts with said packaging material by means of at least one active surface; a flux-concentrating insert; and a supporting body made of heat-conducting material and housing said inductor device and said flux-concentrating insert, wherein said flux concentrating insert is made by a magnetic compound of a polymer and soft magnetic particles; and said flux concentrating insert interacts with said packaging material via at least one interactive surface.

Simplified transversal induction sealing device

A magnetic insert for enhancing the magnetic field of an induction heating device is provided. The magnetic insert is manufactured by use of a composition comprising a moldable polymer matrix and a soft magnetic material.
