Illustrated and described are: a spout element for packaging, in particular composite packaging for liquid foodstuffs, said packaging having a polyhedral gable-shaped region (6) and folded packaging casing flaps (7) and the spout element having a main body (1), a polyhedral flange (4) which is provided for connecting to a packaging casing and the connecting surfaces (9) of which converge at surface meeting points (10); composite packaging for liquid foodstuffs, having a polyhedral gable-shaped region (6) and folded packaging casing flaps (7), in which packaging the packaging casing is connected to the spout in a corresponding manner; and composite packaging for liquid foodstuffs having such a spout element. In order to keep the packaging undamaged and thus leaktight during the connecting process between the spout element and packaging casing and during the folding of the packaging casing flaps (7), provision is made for receiving regions (14) for the folding line (8) of the packaging casing flaps (7) to be formed in the region of the surface meeting points (10).
