Abstract

L’invention concerne un de fabrication d’un sac d’emballage de produits alimentaires comprenant une paroi avant (3a) et une paroi arrière (3b), reliées par des soufflets, un fond, et une ouverture de remplissage, le sac est fabriqué à partir d’au moins un film (1) réalisé à partir de papier traité pour faire barrière aux graisses au niveau d’une face interne du sac , soumis à des opérations successives de pliage, de collage et de coupe pour former en continu le sac d’emballage.Selon l’invention, au niveau du fond (4) du sac, des bords (4a1, 4b1) du film destinés à être en contact avec les produits alimentaires sont repliés sur eux-mêmes et vers l’extérieur du sac pour éviter tout contact desdits bords avec les produits alimentaires destinés à être insérés dans le sac. Figure pour l’abrégé : Fig. 5The invention relates to manufacturing a food packaging bag comprising a front wall (3a) and a rear wall (3b), connected by gussets, a bottom, and a filling opening, the bag is manufactured from at least one film (1) made from paper treated to provide a grease barrier on an internal face of the bag, subjected to successive folding, gluing and cutting operations to continuously form the packaging bag. According to the invention, at the bottom (4) of the bag, the edges (4a1, 4b1) of the film intended to be in contact with the food products are folded on themselves and towards the outside of the bag to avoid any contact of said edges with the food products intended to be inserted into the bag.
