What Film Core Size Should Your Roll Laminator Use?
Thursday, July 8th, 2010
So you have a roll laminator and now need some replacement film for it. So what size core should you get? There are three common sizes available. This includes one-inch, 2 ¼-inch and three inch. Here are a few ways to get the right film for your laminator.
The easiest way is to simply measure the inner diameter of the hole on your old roll lamination film. Unfortunately this isn’t always an option. Often times the old rolls are no longer around or the person that used to buy the film is no longer with the company.
Another way to determine the size of film you need is to measure the mandrel. The mandrel is the rod that the roll film is slid onto. A one-inch mandrel is pretty easy to spot out. The 2 ¼ or three-inch mandrel may require you to break out the tape measure.
As a general rule, roll laminators that fall within the 25 to 27-inch wide range use a one-inch core. The one-inch core diameter is the most common size used today.
Larger roll laminators (30-inches plus) typically use a wider core. This is because the wider film usually requires more stability.
What if you have a one-inch mandrel on your laminator but the film you want to use is only available with a larger 2 ¼ or three-inch core? Some laminator manufacturers make core adapters that will allow you to use a larger core film with a smaller mandrel.

Laminators are great machines aren’t they? Perhaps I am a little spoiled working for an office equipment store, but I laminate a lot of stuff. I have laminated pictures, phone directories, work schedules, business cards and more. There is something about laminating a document that makes it look much more professional. Maybe it’s the glossy sheen, or perhaps the rigidity that it provides.
and on top of the competition, we now have our lamination prices at record low levels. We have been selling lamination film online since 1996, and I think this has to be the best price ever offered.
