Preserving Works on Paper

Encapsulation

Encapsulation is a technique for protecting works on paper that allows an item to be handled and consulted. In this technique, a work is placed between two layers of inert polyester film. The layers of film are then fused at the edges only, leaving the document protected within a sealed pocket or sleeve. Unlike a laminated work, whose surfaces are permanently adhered to non-archival plastic, an encapsulated work can be easily removed from its enclosure if necessary by cutting open its sleeve. Encapsulation also allows the display of double-sided items.
