Optical-grade PET protective film boasts excellent optical properties, including low haze, high transmittance, smooth surface, and tight dimensional tolerances. It is primarily used in high-end LCD devices as external diffusers, reflective films, brightening films, antistatic films, touchscreen protective films, and films for flexible displays. Among the upstream and downstream raw materials for LCDs, optical films are used in backlight units, polarizers, and optical materials.
LCD is a popular flat-panel display technology, widely used in LCD TVs, laptops, monitors, and mobile phones. The demand for optical PET protective film occupies approximately 15-20 times the area of the panel itself, and its cost accounts for approximately 15-20% of the total cost of the LCD. my country has become the world's largest producer and manufacturer of touchscreen materials. Furthermore, the explosive growth of China's touchscreen industry has driven rapid growth in demand for optical films, making them one of the most critical strategic raw materials for the front-end development of the entire optical industry chain.
Optical PET (PET) protective films account for over 80% of the total cost of computer panels, demonstrating their critical importance. Optical films come in many varieties, categorized by their primary application and optical and electrical properties: metallic dielectric reflective films, polarizing films, anti-reflection films, and anti-reflection films. In the production of LCDs, key materials, in addition to the glass substrate, include enhancement films, cyan light control film, color filter, and polarizer.
Color television production in my country has seen significant year-on-year growth. The close integration of optical film technology development with material development has led to a surge in demand for new functional materials. These films, with their advantages of light weight, thin design, low radiation levels, and low power consumption, are widely used in laptops, mobile phones, PC monitors, and color televisions. Demand for these key materials in upstream and downstream markets has also increased significantly.
The PET protective film industry chain is currently in a rapid development trend. As a new type of industrial raw material, polyester film has an environmentally friendly and sustainable modification effect. Its main use follows the development trend of our country and requires continuous expansion, the development and application of various special multifunctional PVC films with excellent performance and intelligence. This will not only promote the development planning of related industries, but also promote the development trend of PET production mode from industrialization to systematic division of labor.
