Abstract (en)
The invention relates to an envelope obtained from a continuous web, which is divided into equal lengths. The lengths of web are divided into three panels (6, 7, 8) by transverse fold lines (4, 5). The first panel (6) and the second panel (7) are folded one over the other and bonded along lines of adhesive (10) to form a bag open on one side and adapted to receive an insert. The third panel (8), which is smaller than the others, constitutes a flap provided with a transverse line of adhesive (11) for the final closing of the envelope.
