Advantages of PET-Based OCA Release Film Over Alternative Materials
PET-based OCA Release Film outperforms PP, PE, and other materials in optical applications. PET offers superior optical clarity, flatness, and dimensional stability. It provides better heat resistance (up to 200°C) than PP/PE. The silicone coating delivers more stable release force and lower silicon transfer. PET’s mechanical strength enables thinner gauges with better handling characteristics. It supports precise coating and die-cutting for high-resolution applications. Unlike alternative materials, PET maintains performance across wide temperature and humidity ranges. These advantages make PET the undisputed choice for high-performance OCA Release Film in demanding display applications.
