1. Roll Width
Measure the distance (in inches) from one flat end of the roll to the other (the length of the cylinder).
2. Core Size
Measure the inner diameter of the cardboard or plastic core around which the film is wrapped, similar to that of wrapping paper or paper towels. This core slides onto the machine’s mandrel and keeps the film held in place during lamination.
3. Film Thickness
Since laminating film is so thin, it is measured in Mil, which is equivalent to only one one-thousandth of an inch. Common film thicknesses include 1.5 Mil, 1.7 Mil, 3 Mil, 5 Mil, 10 Mil.
4. Film Finish
The shine or dullness of laminating film is described as its finish. Gloss is the most popular. More specialized finishes such as Matte may also be available for certain varieties.
5. Footage Length
The long, continuous sheet of laminating film that is wound around the roll of laminating film is pulled from the roll during the lamination process. Use this measurement in combination with the roll width to determine the number of rolls you need for your project.
