Optical PET film is a layer or double layer of film coated on the surface of optical parts to change the optical characteristics of the surface of the optical parts. Optical PET protective film is divided into reflective film, transmissive film, light filtering film, optical protection film, light polarization film, spectroscopic film and bit phase film by application.

　　Optical grade pet protective film has excellent optical characteristics such as low haze and high transmittance, high surface smoothness, small dimensional tolerance of thinness and thickness, etc. It is key used in the industries of external diffusion film, brightening film, reflective film, anti-static protective film, protective film in touch screen and film for flexible display in high-grade LCD devices. Among the upstream and downstream raw materials of LCD, optical films are used in backlight modules, polarizers and optical materials.

　　Optical film PET protective film in the LCD control panel demand

　　LCD is the popular flat panel display technology sex at this stage, widely used in LCD TVs, notebooks, display and cell phones on the industry; optical pet protective film demand covers an area of roughly15-20times the control panel, the cost fee is about 15-20% of the LCD. China has turned into the world&39;s largest touch display material production and manufacturing powerhouse, in addition, China&39;s touch display field explosive growth, promote the demand for optical film rapidly, optical film has turned into optical whole industry chain front-end development more critical development strategy one of the raw materials.

　　Demand for optical films in color TV sets

　　In China&39;s color TV production volume gradually year-on-year growth rate, optical film technology and raw materials course of close integration, prompting the film technology for new new functional materials demand surge, because itself has a lighter weight, thin appearance design, small radiation source and the role of poor consumption and other advantages have been commonly used in notebooks, cell phones PC monitors and color TV, sales market for its upstream and downstream important raw materials The demand for similar optical films has also increased significantly.

　　Demand for optical films in flat panels

　　In the product cost of all computer control panels, optical pet protective film accounts for more than 80% of the product cost; thus, the need for optical pet protective film is evident, and there are many types of optical films, which can be divided into: metal materials, all-electrolytic dielectric reflective film, polarizing film, transmissive film, reflective film, and in the production of liquid crystal displays, its important raw materials, in addition to the glass substrate, is the layer film. In addition to the glass substrate, it is the layer film, glare control module film, colorful light sheet, polarizer, etc.

　　PET protective film industry chain is in Korakuen development trend links, polyester film as cui green, environmental protection, sustainable modified materials of new-style industrial production of raw materials, its main use closely follow the development trend of our country, must be constantly expanded, excellent performance, intelligent development of various special multi-functional pvc film design and use, will not only promote the development of the relevant industrial planning also prompted the PET field production mode from industrialization to systematic division of responsibilities development trend.
