1). Glued Pocket folder or self-locking folder?
With self-locking folders you simply make them up as and when you need them. They are die-cut, creased and flat. Not only do they take up less storage but also it's 'you' making them up so you're not paying for the print finisher to apply a glue strip, make the folders up and then repack in boxes. In addition to this labour saving, your self-lock folders take up less room in storage. If you like a sample(s) of different types of folder mechanisms then contact us and we will send you some.
Capacity pocket folder or non-capacity folder: If your folder needs to hold more than 15 pages and standard weight paper (anything up to 170gsm) then you do not need capacity. Anymore than that then the folder needs capacity which means putting in a double crease on the spine and pocket. So, typically if you're sending a lot of information out you will need anything from 3mm to 10mm capacity. You can still have a self-locking mechanism but they do take longer to make up.
2). Make the pocket smaller. For a folder to take standard A4 items, a pocket of less than 100mm means that your folder can be printed on a SRA2 sheet rather than B2 sheet. This can save a few hundred pounds in some cases.
