IMPULSE HEAT SEALING OF A HEAT-SEALABLE FILM MATERIAL

A sealing station configured to heat seal a wall made from heat-sealable film material, preferably metal-free heat-sealable film material, onto one another wall of heat-sealable material, e.g. another wall of heat-sealable film material, to create a sealed seam. The sealing station comprises an impulse sealing device comprising a first jaw and a second jaw, wherein at least the first jaw comprises at the respective front surface thereof at least one, e.g. a single elongated, impulse heatable member that extends along the respective front surface and that is covered by a heat-resistant non-stick covering.

Heat-sealable packaging material

The present invention is directed to a packaging material free from aluminium in the form of a continuous foil or film, comprising a layer of microfibrillated cellulose (MFC), wherein the layer comprising MFC has been laminated or coated on at least one side with a heat-sealable material. The MFC layer contains at least 60% by weight of microfibrillated cellulose. The present invention is also directed to a method for induction sealing, wherein a packaging material to be heat-sealed by induction is placed against an induction heating surface.

PRODUCTION OF COLLAPSIBLE POUCHES HAVING A FITMENT

A production machine for the production of collapsible pouches having a fitment. The machine has a fitment sealing station with an impulse sealing device comprising a first jaw and a second jaw and with an actuator device configured to move the first and second jaws relative to one another between an opened position and a clamped position, as well as a cooling device configured to cool each of the first and second jaws. The fitment sealing station is configured to perform an impulse sealing cycle.
