These thermoformable, light enhancing films and liners are designed especially for backlit sign applications to improve brightness and increased light output for greater sign reflectance.
Maximise the internal reflection of light in illuminated signs to increase brightness with 3M™ Light Enhancement Film 3635. Our matte white, highly diffusing reflective cast film is 140 µm and comes with a clear, permanent adhesive. It provides extremely high reflectivity of approximately 94-96 %, increasing luminance even more than most reflective materials, including mirrors. It’s designed for application on to the inside of internally illuminated signs to maximise the internal reflection of available light, with up to 7 years durability. With this film neon tubes can be often be reduced in length, or less fluorescent tubes can be used, resulting in lower component costs and energy consumption.
