Wide application of optical grade polyester film-technical knowledge

The extensive application source of optical grade polyester film: protective film factory direct sales Release time: 2019-08-01 Click: 1245 In recent years, the global polyester film industry has grown rapidly and the production capacity has expanded rapidly. However, the domestic polyester film industry has always had structural problems. It is a reasonable phenomenon that most of the films produced on the existing production lines have a single-layer structure or simple performance, and are only suitable for general use. High value-added products and special-purpose products mainly rely on imports. Polyester film has good comprehensive properties and is widely used in packaging materials, electronic insulation, card protection materials, imaging films, hot stamping foils and many other fields. Among them, the thickness of ordinary polyester film used in packaging materials is generally 8μm-75μm (micron, 1μm is equivalent to one millionth of 1 meter), and the thickness of medium-thick special polyester film used in other industrial fields is generally Above 75μm. Optical grade polyester film has excellent optical properties such as low haze and high light transmittance, high surface finish, and small thickness tolerance. It is mainly used for diffusion film, brightness enhancement film, reflective film and antistatic protection in high-end liquid crystal display equipment. Films, protective films in touch screens, and films for flexible displays, etc. Moreover, the application range of optical grade polyester film is constantly expanding, such as anti-ultraviolet heat insulation film used in the automotive field. In addition, in recent years, electronic circuits used in electronic information products have developed into an overall trend toward integration and planarization. This has contributed to the chip-type, miniaturization, high-precision, consistency, reliability, and adaptation of electronic components. The requirements put forward by other parties have brought new opportunities for the industrial development of optical grade polyester film. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 20 years of experience. It can produce PET film with various functions, such as: sub-(matte) PET film, flame-retardant (fire-resistant) PET film, inkjet printing Film, anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, optical PET film, etc. Interested parties welcome to inquire!
