A holder intended for thin sheets, information sheets and the like, and comprising two parallel plastic panels (1, 2). The plastic panels are joined together along at least two joining lines (3, 4, 5) via spacer material, so as to form between the panels a slot-like space (6, 7) for receiving said thin sheets or information sheets (10, 11). The holder has the form of a one-piece structurre in which the spacing material (9) is formed of material obtained from the plastic panels (1, 2), this material being caused to flow out and from the spacing material that joins the panels together, by a high-frequency welding process. The invention also relates to a method of producing such a holder. |
