Frequently Asked Questions

Honestly, it comes down to how much wear the finished piece needs to survive. A 10 mil cover already holds up fine for most everyday reports. You'd step up to 15 mil when the document is going to get passed around a lot, things like training manuals or proposals that need to look sharp after months of use. If you want something that feels almost rigid, like a standalone piece rather than a bound document, 20 mil is worth a look too. Take a minute and compare it against 10mil clear covers side by side. You want enough stiffness to protect the work, but not so much that pages get stiff to turn.

In most cases, yes, but plastic this thick punches a little differently than paper does. Comb, coil, and wire systems can all handle it, though I'd always recommend punching the covers separately rather than tossing them into a stack with hundreds of interior pages. If your punch is on the lighter side, run a small test batch first before committing to a big order, since some smaller machines just aren't built for pushing heavier plastic through repeatedly. Going pre punched sidesteps that whole issue if you're not sure. Just double check the hole pattern matches your binding style exactly. Fixing a mismatched punch on heavier stock is a lot more annoying than it is on thin paper.

That really depends on what you've got in your shop. If you're doing occasional small runs and already have a punch rated for this thickness, punching your own gives you more control over timing and hole placement. But for anything recurring or high volume, going pre punched just saves wear and tear on your equipment. Forcing 15 mil plastic through a punch built for lighter stock over and over will dull blades faster than paper ever would. A lot of buyers who standardize on one binding style across a whole department end up going pre punched for exactly that reason. If your needs shift project to project, it's worth comparing against 7mil clear covers to see how pre punched availability can differ by thickness.

This one's easy to overlook, but yes, it's worth checking before you buy. Not every clear cover is rated for the heat that thermal binding uses, and if you grab a standard one it can warp or cloud up right when you need it looking its best. That kind of defeats the point of a clear cover showing off your title page. If thermal binding is part of your process, look specifically for the heat resistant version rather than assuming a regular 15 mil cover will be fine. It matters most for anything that'll be reused or handed to a client. My advice, always test one cover on your actual settings before running a full batch.

Size it around the whole finished stack, not just the paper. Tabs and dividers stick out past the edge of a standard sheet, so a letter size cover cut only to the paper leaves those edges exposed. That's exactly why oversize options exist, with extra width or rounded corners built in, so the tab titles stay visible without getting crushed during handling. Before you order in bulk, put together one full sample with your actual tabs, paper, and spine. It's a small step that saves a lot of grief, especially since a sizing mistake shows up more on a heavier 15 mil cover. Take a look at 20mil clear covers too if your tabbed document also needs extra rigidity.
