The protective film roll

In terms of function, protective film is a layer of film that is placed outside the physical object we want to protect. Nowadays, there are functional protective films such as AR anti reflective film, AG frosted anti reflective film, mobile phone mirror film, anti peeping film, high-definition anti scratch film, etc. available in the world.
Originally originated from. When the main screen backlight is turned off, the protective film acts as a mirror. When the backlight is turned on, text and images can be displayed normally through the film. The film is divided into 5-6 layers, and one layer is treated with aluminum vapor deposition. Utilize this layer to reflect external light and achieve mirror function.
At the beginning, the main production was concentrated in industrialized countries such as Japan, the United States, and Europe. Due to the earlier industrialization development in Europe and America, the requirements for surface protection of products were introduced earlier than in Asia, in order to reduce the losses caused by surface scratches during transportation, handling, warehousing, and even display of products in the circulation process from factories to the market. European brands dominate the world in the protective film of rubber based adhesives, and due to its characteristics, the protective film of rubber based adhesives is still used in industries with complex post-processing such as stainless steel plates, aluminum plates, and even some plastic parts. Japan started early in the development of non-toxic PVC, PET, and AR materials, and has advanced technology. 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, while exporting PVC, PET, and AR materials abroad. As a major consumer of mobile phones, Chinese Mainland has a large number of production and sales of mobile phone screen protective films. After several years of development, it has been able to produce more high-end protective films. Although there is still a certain gap from the protective films in Japan, there is a trend to completely replace the Korean film at present. In the past two years, Japanese and Korean protective film manufacturers have put into production or established joint ventures in the mainland. As for the production of mobile phone film in China, it mainly operates as a non core business for some tape factories, electronic material factories, and protective film factories. There are relatively few manufacturers specializing in the production of protective films, as the production and coating processes of protective film raw films are complex, and many technical aspects need breakthroughs. Additionally, a good set of blown film and coating lines requires high investment. Therefore, there are not many real manufacturers of protective films, and even fewer can produce excellent raw films. So most factories only stay in the secondary and tertiary processing stages of protective films, which belong to lower levels in the entire protective film industry chain. In terms of regional distribution, it is mainly distributed in Shenzhen, Foshan, Dongguan in Guangdong, as well as some areas in Zhejiang, Shanghai, and Jiangsu. However, with the popularity of touch screen smartphones and the increasing attention to 3G smartphones, the protective film market has also attracted more attention from businesses. Many manufacturers have also started producing high-end protective films to meet the fashion aspirations of young people.
