A blank is provided adapted for forming into a file folder. The blank comprises a planar sheet having a first surface and a second surface. The sheet has a first cover portion joined to a second cover portion along a mutual cover hinge line. The sheet is adapted for folding about the cover hinge line such that the first cover portion and second cover portion overlie each other and the folder is adapted to receive sheet material therebetween. The first cover portion includes a tab extension along one edge thereof either adjacent to the fold line or opposite thereto. The tab extension includes an inner tab portion and an outer tab portion joined together along a mutual hinge line. Folding the tab extension about the tab fold line causes the outer tab portion to overlie the inner tab portion forming a tab which extends from an edge of the first cover portion beyond the second cover portion when the second cover portion is folded to overlie the first cover portion. The inner tab portion and outer tab portion both have labelling areas on their surfaces which are adapted to have indicia printed thereon by a printing mechanism. The sheet is adapted when unfolded to be passed through a printing machine and to have labelling indicia printed on the labelling areas of both the inner tab portion and the outer tab portion. After printing, by folding the outer tab portion to overlie the inner tab portion, the outer tab portion and inner tab portion are secured together to permanently form the tab and present the printed indicia visible on both sides of the tab. The sheet carries an adhesive strip which can be activated after printing such that the adhesive strip secures the inner tab portion to the outer tab portion. |
