Abstract
A process for packing a liquid, semi-liquid, soft or fine-powder product in a closed foil tube, whereby the product is introduced into the foil tube in the area of a tube form station and taken to an expulsion station which expels the product from web-like expulsion areas extending over the width of the foil tube, and adds sealing seams to the foil tube in these areas. In order to achieve proper expulsion and sealing which is simple and tight using narrow sealing seams, the foil must first be cooled off prior to expulsion.
