Document folder inner page booklet

Abstract

A folder inner page booklet is used to install an insert strip inside a folder cover. The inner page booklet includes a plurality of overlapping rectangular inner pages and a combination unit. The combination unit is made of a single sheet of material and has a connecting portion folded from the outside of a first horizontal sheet. The connecting portion forms a lower extension protruding from the lower side of the first horizontal sheet and or an upper extension protruding from the upper side of the first horizontal sheet. Corresponding to the first horizontal sheet, there is a second horizontal sheet that is bent from the connecting portion through a second fold. The first horizontal sheet and the second horizontal sheet form a neck adjacent to the connecting portion. The binding side of the inner pages is thermally fused to the first horizontal sheet or simultaneously to the second horizontal sheet. The inner page booklet can be attached to the folder cover by inserting the connecting portion into the slot of the insert strip. The longitudinal width of the connecting portion forms a resistance to prevent the inner page booklet from detaching from the insert strip.
