1.5 MIL (.0015”) – This is a relatively thin laminate, so it does not add much rigidity to the printed piece. However, the 1.5mil thickness is an economical choice when applying laminate to print materials that are constructed of heavy paper or cardstock, such as business cards, flash card sets, presentation folders, and book or manual covers. Also, because 1.5mil is the least expensive laminate choice, it is also a great fit for laminated print projects that serve a temporary purpose, such as a route map for a walk-a-thon or a limited-time holiday menu for a restaurant. The flexible 1.5mil thickness is also perfect for laminating labels and decals.
Laminated printing refers to printed pieces that have a clear plastic film bonded to them. Printing is laminated to protect it from stains and moisture, to increase its strength and durability, and to add sheen and vibrancy to its ink colors. Lamination makes printed documents look more finished and professional.
The clear plastic film used to laminate printed matter is available in a variety of thicknesses. Some are thin and flexible, others are quite rigid. By the way, if you need a printed piece to be rigid, one tip that can generally save you money is to use a heavy cardstock to print on and then apply a thinner laminate film…as opposed to printing on thinner paper and using a thicker laminate film. If in doubt, tell your printer what your desired thickness result is and then he/she can price it out with the method most economical for you.
