“ARCHIVHUG™“ Special and “ARCHIVHUG™ Open“Special folders are innovative saving space wrappers made from Duralong Special board that enable the long-term storage of archival documents, books and papers in general, saving space on the shelves. Ideal both in the case of a new archival organization and for the replacement of old folders, boxes or containers of variuos kinds. Thanks to the telescopic sliding of the spine, housed inside the front flap and the multiple creases on three flaps (only Archivhug™), they offer a great modularity to cope with no problems to the variable thickness of the content. The model Archivhug™, unlike Archivhug™ Open, is designed to be completely closed and then to fully protect the contents from light and dust. They are equipped with a strong fastener with a herringbone cotton tape glued to the flaps by means of a pH neutral adhesive and white conservation paper.
