Archival Methods Onyx Portfolio Boxes are often the best choice where presentation is as important a factor as storage and protection. This is particularly applicable for photographs, prints and similar art work that are in what we might call live storage, regularly presented or viewed but safely housed in between.
Portfolio boxes have the appeal of being "lockers" that converts to a "stage." Ruggedly constructed and well sealed, Archival Methods portfolio boxes flip open to provide a handsome, complimentary background that enhances and frames the contained works.
Box core is Kappa binder's board (0.1), a bookmaking board with no glue between layers
Lined with 80 lb. acid- and lignin-free paper
PAT tested and passed
Covered in library quality F-Grade Buckram (poly-cotton) with a moisture-resistant, 100% aqueous acrylic coating
Adhesive is pH balanced and buffered, <.0008% sulfur content
Close-tolerance construction to keep out dust
Hinged design allows top to fold open and lie flat, providing easy and instant access; this design, moreover, facilitates transfer of stored items from one side to the other for smooth and professional presentation
An additional and important benefit is that photos, transparencies or documents are subject to less physical handling compared to storage in conventional boxes, further reducing any risk of damage
More specifically, works in portfolio boxes can be edge-handled with fingers never touching the surface of the work
Portfolio boxes are ideal for storing matted or un-matted prints
Strong hinge section withstands repeated opening and closing
Offered in standard 2" depth, with either white or black lining or in 1-3/8" depth with white lining only
