Our adhesive coated magnetic rolls feature a pressure sensitive adhesive that lets you peel-and-stick; simply print your own page using any printer or copier, peel the liner off the magnet, and stick your printed page onto the adhesive side. 30 mil magnetic materials have 85 lbs. of pull per square foot and are ideal for advertising on vehicles, as they are strong enough to hold even at speeds up to 65 miles per hour. These rolls have premium indoor adhesive, which is ideal for indoor applications that require a higher and stronger tack level, such as those adhering to rough surface textures. The other side of these rolls are plain magnetic material with no coating.
