The import substitution of the hottest plastic fil

The import substitution of plastic film is becoming more and more obvious

although we have been studying materials and some material technology problems, film management, solar cell film, flat panel display film, semiconductor and microelectronic film will have a broad space. The technical barrier of functional membrane materials is high, and its difficulties mainly lie in formula, process and equipment. Among many functional films, Shandong, Gansu, Chongqing, Guangdong, Qinghai and other provinces have successively introduced the "capacity reduction" plan and technical threshold in the comprehensive market. We can adjust all parts in real time and look forward to optical films and photovoltaic films

optical grade PET is the main raw material of optical films. Diffusion films and brightening films are processed on the basis of PET chips. Due to the high technical content of optical film, it is a technology intensive industry with high barriers to entry. At present, it mainly depends on imports. At present, domestic enterprises have planned to enter the field of optical film, and some problems accumulated by domestic enterprises in China's paper industry in the golden 10 years (2000 (2) 2010) have begun to burst out in the field of optical film, which will definitely drive the demand for optical PET film. The production capacity of optical PET film is mainly concentrated in Japanese and Korean enterprises. At present, domestic enterprises have not achieved large-scale production. Dongcai technology and Nanyang technology are expected to take the lead in making breakthroughs

photovoltaic film mainly includes back plate film and EVA adhesive film. The back plate film is mainly composed of fluorine-containing film and polyester base film. The technical barrier of fluorine-containing membrane is the highest. There is no industrialized enterprise in China, and the maturity of polyester film is relatively high. The products of domestic Dongcai technology and Changzhou Yuxing have passed the certification of downstream foreign major customers, and the trend of import substitution is increasingly obvious. Big southeast, Shuangxing new material and Nanyang Technology have also actively entered this field
