About this dieline
About this dieline
A self-locking folder is a card folder with no glue at all: two covers that close like a book, and one pocket inside the back cover made of two flaps, one from the side and one from the bottom. A small tongue on the bottom flap pushes through a slot in the side flap and holds the pocket shut. You can ship it flat and fold it in a minute.
Enter the size of one cover and how thick a stack the pocket should hold. The flaps, the tongue and the slot work themselves out from the size. You get a PDF at true size with the cut outline, the folds, the slot and the printable area. The usual size is 9 × 12 in (228.6 × 304.8 mm), made for letter and A4 pages.
How do I fold it?
Fold the side flap over the inside of the back cover first, then the bottom flap up over it. The tongue now sits right on the slot: push it through, so it tucks under the side flap. Then close the folder along the spine.
How thick a stack does it hold?
Set it in Stack thickness, in millimetres: 1 mm is about 10 sheets of office paper, so 4 mm holds about 40. The spine and the pocket's side strips get about that wide. The dieline shows the folder from the outside, the side you print.
