The insert folder or also called folding box with tuck-in cover or folding folder called, is a folding box type, which consists of only one body and manages without gluing. Not only loose sheets such as informational materials, brochures but also presents find their place. After printing, it is punched and grooved. The construction of the box is done by folding all four flaps (two large and two small) onto each other. One of the large flaps contains a slot into which the other flap is tucked in to close.
