Even if glass breaks, debris will stick to the film, and the broken glass surface will remain clean and smooth. This effectively prevents the occurrence of debris puncture and penetration incidents, and ensures personal safety.
In Europe and the United States, most of the building glass is laminated glass, not only to avoid injury accidents, but also because laminated glass has excellent Seismic Intrusion resistance. Membrane can withstand the hammer, firewood cleaver and other weapons of continuous attack, but also can withstand bullet penetration for a considerable period of time, its security level can be said to be extremely high. Glass breaks safely and may break under the impact of a heavy ball, but the entire glass remains in an integral interlayer, with debris and sharp small fragments still attached to the intermembrane. When the glass is broken, the debris will not disperse and will be used on vehicles such as automobiles. Toughened glass needs a large impact force to break, once broken, the whole glass burst into numerous fine particles, only a small amount of broken glass in the frame. Ordinary glass smash when it hits, typical breakage, resulting in many long sharp fragments. When the wire-clamped glass is broken, the tooth-shaped fragments of the mirror surround the opening, and there are more glass fragments around the penetration point, and the length of wire breakage varies.
