  Optical films are everywhere in our lives, from precision and optical equipment, display equipment to optical film applications in daily life; for example, glasses, digital cameras, various household appliances, or anti-counterfeiting technology on banknotes can all be called extensions of optical film technology applications. Without optical film technology as a development foundation, modern optoelectronics, communications or laser technology will not be able to make progress, which also shows the importance of research and development of optical film technology.

According to the different raw materials used, plastic film products can be divided into polyethylene film, polypropylene film, polyester film, nylon film, polyvinyl chloride film and polystyrene film. Among them, BOPP, BOPET and BOPA made by biaxial stretching process are the three main plastic film packaging substrates and are most widely used in the packaging field.
