PACKAGING BAG OF FILM MATERIAL FOR PACKAGING PRODUCTS REMOVABLE THROUGH AN OPENING COVERED BY A FLAP INTEGRATED TO THE PACKAGING BAG, AND RELATIVE MANUFACTURING METHOD
A flexible packaging bag (1) of film material is adaptable to the shapes of packaged products, such as: hygiene, tissue, food, disposable, vacuum-packed products, etc. The packaging bag assumes, when empty, the form of a bag in which one of the two marching parts exceeds the other, in correspondence of not matching sides, to form a flap with holes for fork- lifting. A line (37) prepared for tear-off of suitable length is impressed on the front wall (32) of the bag parallel to its longer side. The tear-off line is covered by a rectangular flap (36) joined on three sides to the front wall of the bag, in the guise of a pocket, to protect the opening that will be created after the wall is broken along the line prepared for tear-off. A band (33) forming a handle is also joined to the bag for raising it. When packaging rolls of sanitary products, the bag assumes a parallelepiped form with rounded edges, when this happens the tear-off line and the flap extend onto the front wall parallel and in proximity to the upper wall, continuing halfway across both side walls. The flap is fixed to the underlying wall by an adhesive strip placed over the free edge.Linvention porte sur un sac demballage souple (1) de matériau de film qui peut être adapté aux formes de produits emballés, tels que : des produits dhygiène, des mouchoirs en papier, des produits alimentaires, des produits jetables, des produits emballés sous vide, etc. Le sac demballage adopte, lorsquil est vide, la forme dun sac dans lequel lune des deux parties correspondantes dépasse lautre, en correspondant à des côtés non correspondants, pour former un rabat ayant des trous pour une élévation.
