Envelope for correspondence, characterized in that it is constituted by a single sheet of transparent and impermeable paper, folded in a conventional way for the regulatory postal formats, which keeps its transparency substantially in all the part corresponding to the front of the envelope, and is opaque in all the part corresponding to the back of the envelope, so that through the obverse can be read the data referring to the recipient and the sender written in the document that is enclosed in the envelope, while remaining the remaining text of the document itself.
