The transparent float glass pieces with different thickness PVB films and scientific combination, in order to enhance the performance of bullet proof glass, glass thickness and PVB thickness increased. Because the glass and PVB film adhesion is very strong, almost as a whole, and the glass has a higher hardness and PVB the film has good toughness, when a bullet hit the glass, the impact of their energy is reduced to a very low level or even zero, so it can not penetrate.
