Protect and keep contamination out.

Conservation boxes

Conservation boxes are one of the most effective ways of preserving documentation in libraries and archives. For one, they avoid contamination with polluting dust particles and reduce the effect of polluting gases. Another advantage which makes these conservation boxes essential is the mechanical protection they offer when handling and consulting documents. They are an initial shield, even in cases of damage due to fire, water or fungus growth due to humidity.

Of simple design, easy to assemble and perfect for storing books, files or loose sheets. Available in corrugated fibreboard or cardboard. Especially recommended for objects with a thickness of less than 20 - 25 mm where other designs, such as boxes with lids or file boxes, cannot be used. Folder boxes are available in different versions:
