(57) The invention relates to a mailer obtained from a continuous web, which is divided
into equal lengths. The lengths of web are divided into three panels (26, 28, 30) by transverse fold lines (52, 54). The middle panel (28) and a second panel (30) are folded one over the other and bonded along lines of adhesion (32 to 35) to form a bag adapted to receive an insert. The third panel (26), which is smaller than the others, constitutes a flap provided with a line of adhesive (38, 40) for adhering it on the rear surface of one of the other panels (28, 30). |
