How to choose the right laminating pouch
Laminating pouches are available in different sizes, finishes and importantly, different thicknesses. Pouch thickness is measured in microns per flap (or side). For example 2x125 = 250 total micron thickness after lamination.
The lower the micron thickness the more flexible your laminated document will be. The higher the micron the more rigid the laminated document will be. As a general rule, the more frequently that your document will be handled the higher the thickness of the pouch required.
