Import substitution of the hottest functional film

  • Detail

The import substitution of functional film materials is becoming more and more obvious

plastic film refers to the film made of PVC, polyethylene, polypropylene, polystyrene and other resins whose legal efficiency is beyond doubt, which is used for packaging and as a film covering layer. During the 12th Five Year Plan period, plastic films, especially functional film materials, will play an important role in emerging industries. Functional film materials have excellent performance, targeted downstream market segments and wide application prospects. Water treatment film, solar cell film, flat panel display film, semiconductor and microelectronic film will have a broad space. The technical barriers of functional membrane materials are high, and the difficulties mainly lie in the formula, process and equipment. Among many functional films, we are most optimistic about optical films and photovoltaic films based on the market space and technical threshold

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, some domestic enterprises intend to enter the field of optical film, and the entry of domestic enterprises into the field of optical film will certainly 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 realized large-scale production. The size of metallographic samples of Dongcai is easy to hold and grind. Technology [16..86% stock bar Research Report] and Nanyang Technology [22.551.58% stock bar Research Report] 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 becoming increasingly obvious. Dadongnan [5.370.37% stock bar Research Report], Shuangxing new material [30.550.66% stock bar Research Report] and Nanyang Technology have also actively stepped into this field since the second half of 2016
