The multiple protections against scratches, explosions and fingerprints achieved by protective film mainly rely on its special materials, multi-layer structure design and advanced production technology.Anti-scratch protectionHigh-strength materials: Protective film usually uses high-strength and high-hardness materials, such as polyester film (PET), tempered glass, etc. These materials have high wear resistance and scratch resistance, and can effectively resist scratches from hard objects such as keys and coins, protecting the mobile phone screen from scratch damage.Surface hardening treatment: Some protective films will also undergo surface hardening treatment, forming a hard protective layer on the surface of the film by chemical or physical methods to further enhance its scratch resistance.Explosion-proof protectionMulti-layer structure design: Explosion-proof protective film usually adopts a multi-layer structure design, including a substrate layer, an explosion-proof layer, a buffer layer, etc. These layers are bonded together by special adhesives to form a whole. When the mobile phone is impacted by external force, the explosion-proof layer can quickly disperse the impact force to prevent the screen from breaking or shattering.Special material application: The explosion-proof layer in explosion-proof protective film usually uses high-strength materials such as special plastics, metal oxides or tempered glass. These materials have high toughness and impact resistance and can play an effective protective role when impacted.Buffer layer design: The buffer layer is usually located between the explosion-proof layer and the substrate layer and is made of soft and elastic materials. It can play a buffering role when impacted, further reducing the impact on the mobile phone screen.Anti-fingerprint protectionAnti-fingerprint coating: The surface of the protective film is usually coated with an anti-fingerprint coating. This coating is made of special chemical materials and has a low surface energy, making it difficult for fingerprints and other oils to adhere to the surface of the film. Even if it adheres to the film, it can be easily wiped off.Nanotechnology: Some high-end protective films use nanotechnology to process the surface of the film, and reduce the residue of fingerprints by forming a nano-level concave and convex structure. This structure greatly reduces the adhesion of fingerprints on the surface of the film, thereby effectively preventing fingerprint contamination.Anti-oil material: In addition to anti-fingerprint coating and nanotechnology, some protective films are made of anti-oil materials. These materials have excellent oleophobic properties and can effectively prevent oil stains, sweat stains and other liquids from diffusing and penetrating on the film surface.In summary, protective film achieves multiple protections against scratches, explosions and fingerprints by using high-strength materials, multi-layer structure design and advanced production processes. These protection mechanisms work together to effectively improve the durability and aesthetics of mobile phone screens and provide users with a better user experience.
