<p>A self-adhesive envelope comprising a transparent sheet enables to solve the problem of simple printing or manual recording of data about the sender, receiver and the contents in the required number of copies. In addition, it can be fastened on a parcel or a letter while its contents are protected from weather effects by the transparent sheet. The self-adhesive envelope with the transparent sheet and lateral bonds on each side, made from an endless belt of sequentially bonded envelopes which are separable along the usual transverse perforations, is characterized by a self-adhesion carrier (1) bonded onto the transparent sheet (3) along three edges to produce a bag for the contents or sheets of paper (2) respectively, and by a leading sheet (6) made of a self-copying paper lying above the transparent sheet (3).</p> |
