Bulletproof glass 
 By a number of films with different thickness of transparent float glass and PVB film multi-chip combination of scientifically, in order to enhance the ballistic performance of glass, glass thickness and the thickness of PVB were increased. Bonding glass and PVB film as very strong, almost as a whole, and because the glass has a high hardness and good toughness PVB film, when the bullets come into contact with the glass, and their impact energy is reduced to a very low level even zero, it can not penetrate. Similarly, the impact of metal only and can not penetrate the glass shattered. Therefore play a bullet-proof anti-theft effect. The thickness of the monolithic glass and finished as the use of the total thickness of the glass place may be. Bullet-proof glass can be used as military defense, the bank's security guard counter glass, jade jewelry, gold and silver jewelry and other valuables display cabinets and other specific working and living places.
