Frame Backings

Rather than using a cardboard frame backing that offers little protection, Poster Frame Depot uses acid-free foamcore for better protection for your photos, posters, and most artwork. A lesser quality cardboard backing attracts mold and offers little protection from moisture seeping into your framed art work. Quality foamcore backing consists of a thick inner core of polystyrene, a stiff foam, with protective bufferd paper on either side. Our acid-free foamcore is a sturdy backing made for framing, that is buffered with an Alkaline chemical, which helps to combat the acids found in most posters or prints. Available in sized up to 42x62.
