Abstract

L'invention concerne un procédé permettant de produire des sachets d'emballage (10), qui se caractérise en ce que des zones de recouvrement (22 à 25 ; 22a à 25a) à base de colle thermosoudable sont appliquées avec un dispositif de revêtement, sur différentes faces d'une bande de matériau (35). Ladite bande de matériau (35) consiste en papier et peut être recyclée. La configuration et la structure spéciales des zones de recouvrement (22 à 25 ; 22a à 25a) permettent de minimiser la consommation de colle thermosoudable et de matériau d'emballage, de sorte que les sachets d'emballage soient particulièrement économiques à produire.
