Lamination is a way to protect your media from external impact such as dirt, scratches and in some cases, UV radiation. The laminate also affect the media's appearance and luster. There are different thicknesses of laminate, usually expressed in "micron." A higher micron gives a stiffer product, and in some cases better protection. A lower micron can be used if the product should be folded, rolled or bent. When you use lamination pouches, place your media in a plastic pouch which then merges by warmth of the machine. With roll laminating machines, you can also choose to laminate one side only.
