(54) Self-opening envelope


(57) An envelope is provided with a string assembly (22) disposed along the line of fold (18) of the sealable flap. The string assembly is pressed into position with a coating of a pressure adhesive, which is co-extensive with the line of fold. One envelope corner is weakened, so that pulling outwardly 2 from this corner will tear the envelope and will open it along the string assembly, which acts as a knife edge.
