The envelope (11) has a front side (12) and a rear (14) side, a sealing flap (16) connected to the front side, and a rear folding flap (20). Side flaps (18) reach as far as the sealing flap, and the rear fold flap is narrower than the envelope at least by the width of the side flaps. The rear fold flap is separated from the rear side by a fold line (21) and side incisions (23) which extend at a distance from the side edges and parallel to these as far as the fold line.
