It is an object of the invention to improve the strength of a packaging pouch (2) for products such as wet wipes. For this purpose the invention involves adding an upper gusset connecting the front and rear faces of the packaging pouch and attaching the flap to this upper gusset through a slit made in the front face of the packaging pouch. As an illustrative embodiment, the packaging pouch (2) is generally envelope-like, having in particular a rear face (4) and a front face (6), the front face (6) being provided with a dispensing window which can be closed by a flap (8), and the upper edges (4a, 6a) of the rear face (4) and front face (6) being bonded to the inner layer of an upper gusset (12); which upper gusset (12), flap (8) and front face (6) are all joined together. Also, the upper edge (6a) of the front face (6) has at least one slit (22) through which at least part of the inner layer of the upper edge (8a) of the flap (8) is bonded onto a part of the inner layer of the upper gusset (12). |
