Abstract
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.
