Laminate extends the life of your card by adding durability. It prevents scratches, fading, and rub-off from being taken in and out of a wallet or holder. Either thickness of 0.5 or 1.0 mil will work for your application. The thicker option provides even more durability. After choosing your thickness, pick out the coverage you need depending on your card style. If you have more questions or need guidance, call us at (877) 379-8844 or email email@example.com.
