Mylar 5x25 Glowbox LED Light Box Poster Frame

Light up your Mylar!

Original movie theater Mylars usually measure at 5 x 25 inches. All mylars were acquired directly from a movie theater.

A brief history lesson of mylars: Prior to 1989, movie theaters did not use mylars. Mylars were created as a response to the multiplex explosion of the late 1980s. No longer using just 1-2 screens, movie theaters now found themselves with multiple screens and a need to be able to direct patrons to their correct theater, enter the movie mylar!

*Our new computer dotted LED panels provide a uniform light distribution, also aiding with reducing any damages during the shipping process. An updated rotary dimmer comes with each new Glowbox LED Frame. Occasionally, a few scratches or small hot spots may be visible on the face of the panel. This is a normal result of extruding the acrylic panels.

The masking peel on the LED acrylic helps to possibly reduce or eliminate these dots or scratches. The underside of the LED acrylic is where the laser etched dots are located, and scratches or dots that may develop in shipping are typically not visible on the face of the LED acrylic or when the poster is installed.  The sensitive zone is the “face” of the LED acrylic, the customer needs to remove this film when they receive the frame.  BEFORE, we were removing this masking and during transit, if any grit was on this face area, and rubbed in, it would make those hot spots.  By leaving the masking on, the grit won’t damage the LED acrylic face.
