The background cardboard creates a border for an exhibit which is not entirely filling the frame. The colour can be selected accordingly. It can either be used for mounting or fixating pictures or simply as a design element. Its paper-like structure is suited much better than the rigid foam board underneath. The cardboard consists of the same material as a passe-partout – only without cut-out. For its background cardboards HALBE uses only certified KLUG museum cardboard to meet even the highest conservation demands. The cutting can be up to 1800 x 2500 millimetres.
