A description is given of a holder, such as an envelope, which is produced from a paper-type material composed of layers. The holder comprises a holder body which comprises two body surfaces (2, 3) which are joined to one another by means of fold seams (6, 7) and which form a single piece. The two other sides (4, 5) may be formed, by suitable adaptation, into closable sides, or else one side may be permanently sealed while the other side is made into a closable opening by suitably cutting away material. The invention also relates to a method and a device for forming a holder of this kind and to a device for producing a holder, such as an envelope. |
