Optical PET Polyester Release Film liner for Backlight Frame Adhesive Glue
product detail
High-Precision Optical PET Release Film for Backlight Frame Adhesives
Product Overview: Our Optical Grade PET Release Film is specifically designed to meet the rigorous demands of the display industry, particularly for backlight frame adhesive (black & white double-sided tape) and thin-film component lamination. Using high-purity polyester film as the substrate, we apply an ultra-uniform silicone coating in a Class 1000 cleanroom. This ensures that the adhesive maintains a perfect profile with no "orange peel" or surface distortions, which is critical for the uniform light path of modern display modules.
Technical Specifications & Performance Highlights
-
Exceptional Surface Smoothness: Engineered to be free of scratches, pinholes, and dust particles, ensuring the adhesive layer is flawlessly flat for delicate backlight assemblies.
-
Precise & Stable Release Force: Available in customized peel strengths (Ultra-light to Heavy) that remain stable even after long-term storage, preventing "pre-release" or "adhesive locking."
-
Ultra-Clear Optical Quality: High transparency and low haze make it ideal for automated optical inspection (AOI) during the die-cutting and lamination processes.
-
Minimal Thermal Shrinkage: High dimensional stability ensures the film won't warp or shrink during high-speed lamination or heat-aging, preserving the precision of frame adhesive shapes.
-
Zero Silicone Migration: Advanced curing technology ensures the silicone release agent stays on the film, preventing contamination of the backlight unit's optical layers.
