Expansions folders with flaps
Expansion folders, also called “Juris Folders”, are made from a single sheet, with multiple scoring on the flaps and back. Customer imprints possible. The folders can be delivered with loose or pre-stuck base reinforcements. This prevents the originals being archived against external damages that can get caused due to bending. This minimal enhancement increases the value-for- money aspect to a great degree.
A large range of standard sizes available ex-stock.
