AbstractA module for postal transmission, particularly for confidential information such as bank statements and the like, according to the invention has at least four sections (13, 15, 17, 19; 313, 315, etc.) defined by parallel fold lines (7, 9, 11; 331, 332, etc.) for repeated folding; on one of the external sections (13; 313) of the module, in the fully-folded configuration, a window (F, F1) is provided for the address; the useful face of these sections is surrounded by a perimetrical strip for permanent sealing (23A, 23B, 23C; 623) to assure the inviolability of said face, while on the reverse side of it a non-permanent glueing (25B, 25C; 125B, 125C, etc.) is provided. With respect to the known cross-folding modules, the module of the invention has a larger useful surface available, assures a higher production rate and is more easily handled.
