In several major rapidly developing industries in China, such as the LCD screen manufacturing,
optical products protection, glass, steel, electronics, automotive, digital products and other
industries are all filled with figures of protective film, as a surface protection against dust, maintain
a clean protected content, to avoid loss and scratches during transport. No matter in what industry,
in any field, protective film is playing an important role. Because of the wide usage of protective film,
its development has received increasing attention. Development of functional protective film has
made progress and China started relatively late. Meanwhile the production of light-sensitive material
and the insulating material is gradually developing into packaging substrate, including 60% of film
market,23% of electric special film, 10% of light-sensitive material and 5% of painted decoration film.
Application of protective film material in the industrial sector is developing rapidly and it is making
higher demands of the quality and characteristics of protective film. The development and application
of protective film is mainly risen in the early 1970s in a number of countries such as Japan, United
States and Europe. Through decades of development, protective film is now widely used in machinery,
instruments, electronics, shipbuilding, construction, automobile manufacturing and other industries.
China started in the middle period of the 1980s and grew up in the early 1990s. Therefore, there is a
certain gap between China and developed countries in aspects such as basic research, production
technology and application of protective film. According to base materials, developed countries divided
protective film into dozens of different kinds. According to processing purposes, it is divided in to
protection films for simple protection, for light processing, for semi finish and for heavy processing.
As a country with lots of consumers of mobile phones, currently production and sales of mobile phone
screen protective film are more, but these are generally low-end protective films. The raw materials are
mainly from Japan. Speaking on production of mobile phone protective film, some adhesive tape factories,
electronic material factories and protective film factories are running it as non-core business. Certainly
there are also factories specialized in manufacturing protective film, such as Shenzhen Taiji Opto-elec
Co., Ltd. In terms of original distribution, these protective film factories are distributed in Shenzhen and
Dongguan in Guangdong, and some areas in Zhejiang and Jiangsu, of which the most in Shenzhen,
accounting for nearly 80% of manufacturers and production share. But as nowadays touch-screen
mobile phones are popular and people concern about 3G mobile phones, protective film market is also
getting more business concerns.
