Functionally, the protective film is to put a layer of film on the physical object we want to protect. There are now functional protective films such as AR anti-reflective film, AG matte anti-reflective film, mobile phone mirror film, anti-peep film, and high-definition anti-scratch film on the market.
Originated from. When the backlight of the main screen is off, the protective film plays the role of a mirror. When the backlight is turned on, the text and images can be displayed normally through the film. The film is divided into 5 to 6 layers, and one of the layers is aluminum evaporated. This layer is used to reflect external light to achieve the mirror function.
The main production was initially concentrated in industrially developed countries such as Japan, the United States, and Europe. Due to the early industrialization of Europe and the United States, the requirements for surface protection of products were entered earlier than in Asia to reduce the losses caused by surface scratches in the circulation link from the factory to the market during transportation, handling, warehousing, and even display of products. European brands are unique in the world in rubber-type glue protective films, and rubber-type glue protective films are still in industries with complicated post-processing such as stainless steel plates, aluminum plates, and even some plastic parts due to their characteristics. Japan started earlier in the development of non-toxic PVC, PET, and AR materials, and its technology is more advanced. Therefore, the development of mobile phone screen protectors in Japan and South Korea is also relatively rapid. Japan and South Korea mainly produce mid-to-high-end mobile phone protective films, and export PVC, PET, and AR materials to their foreign countries. As a major consumer of mobile phones, mainland China produces and sells a lot of mobile phone screen protectors. After several years of development, it has been able to produce higher-end protective films. Although there is still a certain gap between the protective films of Japan, for now, there is a trend of completely replacing Korean films, and in the past two years, Japanese and Korean protective film manufacturers have already started production or established joint ventures in the mainland. As far as the production of mobile phone films in China is concerned, it is mainly operated as a non-main business of some tape factories, electronic material factories, and protective film factories. There are few manufacturers specializing in the production of protective films because the production and coating process of protective film raw films is relatively complicated, many technical aspects need to be broken through, and a good set of film blowing and coating lines requires high investment, so there are not many real protective film manufacturers, and even fewer can make good raw films. Therefore, factories only stay in the secondary and tertiary processing stages of protective films, which belong to the lower stage in the entire protective film industry chain. In terms of regional distribution, it is mainly distributed in Shenzhen, Foshan, Dongguan in Guangdong, and parts of Zhejiang, Shanghai, and Jiangsu. However, with the popularity of touchscreen mobile phones and the focus on 3G mobile phones, the protective film market has also attracted the attention of more businesses. Many manufacturers have also begun to produce high-end protective films to meet the fashion pursuits of young people.
