<p>The document holder comprises a rigid sheet of plastics or similar material which forms a back support. This sheet is provided with plastics strips along one long side and two short sides, used to hold the edges of the document. The strips are U-shaped, their bottom face being heat welded to the side of the rigid sheet, leaving the legs of the section to form flaps. Other flat coloured strips can be placed over the holding strips to provide identification. A transparent overlay may be inserted over the document as a protection.</p> |
