[0002] Tempered glass is actually a kind of prestressed glass. To increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby increasing the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. Tempered glass protective film is a higher level of security protection for mobile phone screens;

[0003] Among them, a double-layer tempered glass film with authorization announcement number CN216919126U in the prior art includes a main film structure, the main film structure includes a tempered main film, an attached bottom film, a silicone coating, a release protective film, a release film tear strip, a camera opening and a small wavy widened edge, auxiliary end corners are adhered to the four corners of the main film structure, the auxiliary end corners include an end frame main block, a main film corner card slot, a friction-increasing groove surface, and a film corner adhesion groove, the bottom side of the tempered main film is fixedly installed with an attached bottom film, the bottom side of the attached bottom film is coated with a silicone coating, the bottom side of the silicone coating is adhered with a release protective film, and the front side of the release protective film is fixedly installed with a release film tear strip;

[0004] The tempered glass film in the prior art is not very resistant to falling and can withstand a small impact force, so the screen is still at risk of breaking.

For this reason, we propose a double-layer tempered glass film. Utility Model Content
