Thickness is the whole decision. A light gauge is fine on a report read once and filed, and it folds and clouds along the spine on a manual opened every day. Heavier stock holds its shape and costs more per document. Pair a clear front with an opaque back so the first page reads and the last is protected. See thermal binding covers, leathergrain covers and binding machines.
