Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a frameless anti-scratch PET protective film. Background Art

[0002] PET film is a packaging film with excellent performance. It has good transparency and gloss; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, and its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than those of ordinary films. PET film also has excellent heat resistance, cold resistance, good chemical resistance and oil resistance. Mobile phone film, also known as mobile phone beauty film and mobile phone protective film, is a kind of cold mounting film that can be used to mount the surface, screen and other tangible objects of mobile phone body. There are many kinds of mobile phone films. Mobile phone films are not only limited to mounting mobile phones, but also can be mounted on MP3, MP4, computer screens, mice, speakers and any physical objects that need to be protected. Because it was originally widely used for mobile phone beauty, it is named "mobile phone film". Because the mobile phone mounted with mobile phone film can be brand new and bright, it can not only play the effect of refurbishing old machines, but also can be waterproof and prevent dust from entering the keyboard and screen, and play a protective role. Therefore, people also commonly call it mobile phone beauty film and mobile phone protective film.
