<p>The bag (10) has a pouring part (20) provided in a region of a tetrahedron corner of the bag, and protruding from the bag in a tubular manner. The pouring part is closed on a free end (22) of the pouring part. An opening cross-section in a region of transition between the bag and the pouring part is stabilized by a reinforcement element i.e. folded seam (30), in a film material of the bag. The reinforcement element extends transversal to a pouring direction (y) opposite to the tetrahedron corner, and is formed from a plastic material.</p> |
