my country’s triacetylcellulose membrane (TAC membrane) industry is embracing development opportunities. There is huge room for domestic substitution in the TFT-type TAC membrane market.

Cellulose triacetate film, also known as TAC film, refers to a film material with cellulose triacetate as the main component. TAC film has the advantages of good high temperature stability, good mechanical properties, good transparency, lightweight, and high tensile strength. It has broad application prospects in many fields such as electronics and electrical, food packaging, medical and health, water treatment, etc.

According to the “2023-2028 China Triacetate Cellulose Film (TAC Film) Industry Market In-depth Research and Development Prospects Forecast Report》 shows that the electronic and electrical field is the largest demand end for TAC film. As a raw material for polarizers, it can be used to manufacture LCD liquid crystal displays. In recent years, my country’s LCD screen market space has continued to expand, and the application demand for products such as TFT LCD screens, MINI LCD screens, and IPS LCD screens has continued to grow. TAC film can be used to protect LCD polarizers. In 2022, the global demand for TAC films for polarizers will exceed 1 billion square meters. In terms of the local market, my country is the main consumer of TAC film, accounting for nearly 30% of the global market.

TFT polarizer is usually composed of PVA film, TAC film, LR/AR layer, PSA pressure-sensitive adhesive AG film. The full name of TFT type TAC film is TAC film for TFT type polarizer. It is widely used in TFT LCD liquid crystal displays and is a representative product in the TAC film market. However, currently, due to factors such as high technical barriers and high production costs, my country’s TFT TAC membrane is highly dependent on imports. In the future, as local companies continue to exert their efforts, the localization process of its market is expected to accelerate.

In terms of the global market, the TAC film market is monopolized by Japan and South Korea. Japan’s Konica Minolta Co., Ltd. (Konica Minolta), Japan’s Fujifilm Co., Ltd. (Fijifilm), and South Korea’s Hyosung Co., Ltd. are the world’s major TAC film manufacturers. The above three companies all have mass production of TFT-type TAC films. capabilities, among which Konigminolta and Fujifilm occupy nearly 80% of the global TFT TAC film market. In recent years, as the global display panel industry has gradually shifted to my country, the number of new production lines built by leading overseas TAC film companies has been decreasing, which has brought development opportunities to my country’s TAC film industry.

Attracted by market prospects, the number of companies in my country that are engaged in R&D and production of TAC membrane industry continues to grow. Lucai Optoelectronics, Tianlu Technology, Xinlun New Materials, etc. are representative TAC film companies in my country. Lucky Optoelectronics is a subsidiary of Lucky Film and is the only company in my country with large-scale production capabilities for TFT-type TAC films. In 2022, its annual production capacity of new TFT-type TAC films will reach nearly 25 million square meters. According to the annual report of Lucai Optoelectronics, the company will achieve revenue of 230 million yuan in 2022.

Industry analysts said that as an important component of polarizers, TAC film has strong market demand and the industry’s development prospects continue to improve. As my country’s display panel market space continues to expand and overseas production capacity gradually shrinks, my country’s TAC film industry will usher in development opportunities. In the future, as local companies continue to exert their efforts, the market share of my country’s domestic TFT-type TAC membrane will further increase.
