ClearShield™ 5 Mil Opaque Backer Low Melt is a 100% opaque, white, polyester film designed to be applied to the back of a trade show graphic. It is flexible enough to allow graphics to be rolled into shipping containers, but provides enough rigidity and lay-flat memory to enable the graphics to remain flat and curl-free when mounted. The light-blocking capability and lay-flat memory of this film make it a good choice to use with ArmorGuard or DisplayGuard to encapsulate images that will be mounted in pop-up booths.
