SEALING APPARATUS AND METHOD FOR SEALING PACKAGES

The invention relates to a sealing apparatus and a method for sealing packages. The package comprises a base foil (22) and a cover foil (5), the base foil (22) and/or the cover foil (5) being formed from a water-soluble foil web (23). The apparatus comprises a liquid supply for a water-containing liquid (3), at least one moistening unit, and a pressing device (24). The moistening unit is formed as a spraying device (4) for contactlessly spraying the liquid (3) onto the water-soluble foil web (23) and is positioned at a distance (a) from the water-soluble foil web (23). The spraying device (4) comprises an electromechanical spraying system (30) with a row of outlet nozzles (31) for contactlessly spraying the liquid (3) onto the water-soluble foil web (23). The water-soluble foil web (23) is supplied to the sealing apparatus (1). The spraying device (4) is positioned at a distance (a) from the water-soluble foil web (23). A water-containing liquid (3) is sprayed onto the water-soluble foil web (23) by means of the spraying device (4). The cover foil (5) is led onto the base foil (22) and is pressed and sealed together with said base foil, in the state in which they are wetted with the liquid (3), by means of a pressing device.
