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..
The Heritage Corrugated Board exceeds the quality of other boards available on the market today. Passing much more stringent testing for permanence than simply the Photo Activity Test, this is the next generation board available today.This multi-use board is typical blue/gray on one side and white on the other, making it perfectly suited for backing boards for framing. E-flute is 1/16" deep and the maximum size is 50" x 60". B -flute is 3/16" deep and the maximum size is 48" x 96".
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".
