Question: what is the difference between 3 mil and 5 mil laminating pouches?
Answer: The higher the mil, the thicker and more rigid the laminating will turn out. Pouch films generally come in 1.5 mil, 3 mil, 4 mil, 5 mil, 7 mil, and 10 mil. Thicker laminating pouch films, such as 7 mil and 10 mil, will often be very stiff and sturdy. 5 mil and under pouch films will be more flexible and thin.
