Shadow-Block Backing Films

About the Shadow-Block Backing Films

Our Unique backing film series is designed to do just that, "block shadows". Light can bleed through other films, allowing display hardware to show through.

Backing films are not optically clear, they are colored to obtain some level of opacity. Although in practice, many over-laminates are used every day on the back of images. Specialized backing films are designed with a focus on rigidity and lay-flat properties. These thick backing films are designed not to retain curl set from being rolled up for extended periods of time.

Shadow-Block C

Composite backing films that are 100% opaque, Shadow-Block C comes in a wide variety of thickness and provides 100% opacity. Designed primarily for pop-up displays, Shadow-Block C helps you eliminate curl set that can result from display panels that have been roll up for extended periods. With a sheet of aluminum sandwiched between multiple polyester film layers and an industrial thermal copolymer adhesive, Shadow-Block C is the optimum choice. With 3 different thicknesses for main panels and end caps, Shadow-Block C is a great option for price and performance when creating pop-up displays.
