<p>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.</p> |
