KernowJet Opaline Light Box & Backlit Signage Film

Backlit film is a deceptively technical product far more than a simple "milky" sheet stretched over a light source. KernowJet Opaline is engineered to solve the problems that matter most to print businesses and end-users working with light boxes and illuminated displays: even light diffusion, strong day/night performance, and graphics that stay sharp under constant illumination.

At the core of every Opaline finish is a light-diffusing back-coat that hides internal lighting elements from view, spreading light evenly across the surface instead of leaving hot spots or visible bulbs and LEDs. The result is a cleaner, more professional-looking display, whether it's switched on or off. A high-resolution front coating ensures graphics stay sharp and vibrant, with a superb colour gamut whether the display is viewed front-lit during the day or backlit after dark.

Built for real-world display environments, Opaline features a scratch-resistant surface suited to scrolling light boxes and high-footfall locations, plus an antistatic treatment that prevents dust attraction and media slipping during printing meaning cleaner runs and more consistent results. It's also weather-resistant, making it a dependable choice for both indoor and outdoor backlit applications.

Opaline is available in three finishes to suit different display needs: Satin, offering a refined, low-glare surface; Frost, delivering a softly diffused, frosted aesthetic; and Gloss, for maximum vibrancy and colour pop. Whichever finish fits the application, all three share the same engineering behind the scenes even illumination, durability, and colour performance that holds up over time.

Opaline's core benefits carry across all three finishes, with each one suited to a slightly different look and application.

All three finishes are ideal for light boxes and backlit applications across retail, advertising, and premium signage indoors or outdoors, day or night.
