A cigarette packet of a laminated sheeting is disclosed which comprises an outer, thermally-bonded weldable layer, and wherein the end flaps of the blank forming the packet are joined to each other and project beyond the end sides. The end flaps are folded in such a way that an inner, longitudinal end flap bears on the packet contents, and two side end flaps are folded on this longitudinal end flap, and a second outer longitudinal end flap on the side of the first inner longitudinal end flap. The particular improvement disclosed utilizes a laminated foil having on both sides an outer thermally bondable layer, which extends over the entire end face of the layer and along an edge turned toward the edge of the inner longitudinal end flap. The side end flaps are joined at their diagonals along a welding strip which extends on a diagonal fold line adjoining the weld strip which extends along the length of the end face.
