China’s PET optical base film market development status and analysis of key companies in 2023

Optical film refers to a film that is plated or coated on optical elements and uses the principle of light interference to change the optical properties of the carrier. It is one or more layers of dielectric films or metal films or a combination of these two types of films. PET optical base film is a film supported by biaxial stretching of polyethylene terephthalate polymer. It has the characteristics of high light transmittance, low haze, high brightness, etc. It can be used as an optical base film for the production of brightening products. Film, diffusion film, release film, ITO film, MLCC film and other optical films.

China is the world’s largest panel producer, but the optical base film, which is the core material of the panel, is highly dependent on external sources. Currently, optical base films are mainly divided into PET optical base films, PVA optical base films and TACV optical base films based on materials. PET optical base films are commonly used optical base films and are widely used.

Optical base films account for a higher cost of optical films, but product production has higher technical barriers. China’s optical film field started relatively late. For a long time, core materials have been highly dependent on foreign countries. However, with the gradual growth of China’s display industry, China’s demand for optical film materials continues to grow, and the localization of the optical film industry chain has become inevitable. trend. In recent years, China’s PET optical base films have continued to develop, and the localization level of domestic optical base films has increased.

The “2023-2027 PET Optical Base Film Industry In-depth Market Research and Investment Strategy Suggestions Report compiled and released by the Industrial Research Center shows that, The panel industry is a capital-intensive and labor-intensive industry. After years of industrial development, the panel industry has gradually concentrated in mainland China from Japan, South Korea, Taiwan and other places. A number of domestic panel manufacturers such as BOE, TCL and Shenzhen Tianma have emerged, which is the mainstay of mainland China. Panel market share continues to grow. As the downstream panel industry continues to grow, China’s panel material industry is also continuing to develop, and China’s optical base film industry’s production capacity has also continued to grow in recent years. For a long time, the optical base film market has been mainly monopolized by giants such as Mitsubishi Resins, Toray, Teijin, DuPont, and SKC. The supply capacity of Chinese optical base film companies is relatively low. However, in recent years, companies such as Doublestar New Materials, Dongcai Technology, Changyang Technology, and Kangdexin have all built optical base film production lines, and China’s optical base film supply capacity has gradually increased.
