Bullet-proof and theft-proof glass consists of several transparent float glasses with different thicknesses and several PVB films. In order to enhance the bulletproof and anti-theft performance of glass, the thickness of glass and PVB is increased. Because glass and PVB film are very firmly combined and almost become a whole, and because of the high hardness of glass and the good toughness of PVB film, when the bullet hits the glass, its impact energy is weakened to a very low level or even zero, so it cannot penetrate. Similarly, the impact of metal can only break the glass but can't penetrate it, so it has the function of bulletproof and burglarproof. The thickness of each piece of glass and the total thickness of the finished glass depend on the place of use.

Bullet-proof and theft-proof glass can be used for military defense, guard glass for bank counters, display cabinets for valuables such as jewelry, jade, gold and silver ornaments, and other specific work and living places.
