Product Overview
ORACAL 8870 Blockout Cast Vinyl Film is a specialized cast film designed for illuminated sign fabrication where selective light blocking is required. By preventing light transmission through designated areas, ORACAL 8870 allows sign makers to create sharp contrast, highlight graphic elements, and produce sophisticated illuminated sign designs.
Commonly used alongside translucent sign films such as ORACAL 8500 and ORACAL 8800, ORACAL 8870 helps fabricators create custom lighting effects that enhance visibility, branding, and overall sign appearance.
In illuminated signage, controlling where light appears can be just as important as the graphics themselves. ORACAL 8870 blocks light transmission through selected areas of a sign face, allowing illuminated and non-illuminated elements to work together for enhanced visual contrast.
This capability is frequently used to create outlines, borders, logo details, lettering accents, and custom lighting effects that improve readability and strengthen brand presentation.
ORACAL 8870 is widely used in the fabrication of channel letters, cabinet signs, pylon signs, monument signs, and other internally illuminated displays. Its premium cast construction allows the film to conform smoothly to sign faces while maintaining dimensional stability throughout the life of the installation.
The result is crisp graphic definition and consistent performance in both day and nighttime viewing conditions.
Manufactured using a cast PVC process, ORACAL 8870 delivers excellent conformability, minimal shrinkage, and long-term durability. The film is engineered to withstand demanding outdoor environments while maintaining its ability to effectively block light transmission.
This makes it suitable for permanent commercial signage and architectural branding programs where reliability is essential.
ORACAL 8870 is often used in combination with translucent illuminated sign films to create complex sign face designs. By layering blockout and translucent materials, sign fabricators can create dramatic illuminated effects, improve visual hierarchy, and enhance overall sign performance.
This flexibility makes ORACAL 8870 an important component in advanced sign manufacturing workflows.
Compatible with standard computer-controlled cutting systems, ORACAL 8870 can be cut into logos, lettering, borders, patterns, and graphic elements with excellent precision. The film weeds cleanly and integrates easily into professional illuminated sign production environments.
ORACAL 8870 provides sign professionals with precise control over illuminated sign design. Its ability to block light transmission while maintaining the performance advantages of a premium cast film makes it an essential material for creating high-impact channel letters, cabinet signs, and architectural illuminated graphics.
