Abstract

The specification represents and describes a cuboid flat gable package made from a multi-layer composite, with the composite having at least one carrier layer made from paper or cardboard, a coupling layer, a barrier layer and a double-sided plastic coating made from polyethylene (PE), with an opening area provided in the package gable which forms the pour opening after the severing, with a pouring element provided with a reclosable closing lid whose flange encompassing the opening area is rigidly connected to the package surface, with the closing lid simultaneously representing the opening mechanism. A reliable connection of pouring element and package gable is ensured in such a way that the opening area is provided with a weakening for support, that the pouring element is arranged on the side of the package surface on which the gable seam is folded and that the part of the flange of the pouring element facing the gable seam reaches approximately up to the gable seam and up to the folding edge of the package tab and is fixed between package surface and folded gable seam. Furthermore, a process to produce such a flat gable package is described.
