CUSTOM SIZED ARCHIVAL BACKING BOARDS - Shipped in (1) business day
Backing boards act as a barrier against acid migration and dust, fill space, and add rigidity to the finished frame package. Metropolitan carries a variety of archival backing boards for that purpose..
Coroplast® Archival is a custom frame backing board that is chemically inert, extremely durable plastic material used for backing. It is composed of extruded twinwall fluted polypropylene copolymer. It is free from additives such as coloring agents and antistatic & ultraviolet inhibitors. Coroplast is very popular with museum preparators because it is a superior long-term substrate with no out-gassing. Because of its translucent and fluted qualities, Coroplast is best-suited to be used in conjunction with a 4 ply sized board, to add support and rigidity, rather than be a single backing in contact with one’s art. They are available in 1/8" and 3/16" widths. Maximum size is 48" x 96".
