Abstract

La présente invention concerne un procédé de fabrication de sac d'emballage qui effectue séquentiellement des opérations d'impression et de fabrication de sac. Le procédé se caractérise en ce qu'il comprend : l'étape d'impression consistant à dérouler (15) un film stratifié lisse comprenant une couche en matériau de base, une couche de dépôt en phase vapeur et une couche d'étanchéité, acheminer ledit film dans l'imprimante à jet d'encre (17), puis pulvériser une composition d'encre durcissant aux ultraviolets par la tête de l'imprimante afin d'imprimer un dessin souhaité comprenant des informations sur le produit et un motif sur une surface donnée de la couche en matériau de base du film stratifié, et l'exposer ensuite aux ultraviolets (18) afin de durcir la composition d'encre durcissant aux ultraviolets ; et l'étape suivante de fabrication de sac consistant à acheminer le film stratifié imprimé à une machine (10) destinée à la fabrication de sacs et à l'emballage, qui permet, tout en donnant (13) au film stratifié une forme de tube, de fermer hermétiquement et longitudinalement les deux faces terminales du film stratifié dans leur longueur et qui permet, perpendiculairement à la longueur du film stratifié, d'effectuer une fermeture hermétique latérale à intervalles donnés afin de fabriquer le sac.
