Security film enhances the safety of existing glass in buildings by improving the capability of glass to absorb impacts from projectiles or accidental breakage. In the event of the glass being broken, the glass will shatter but stay adhered to the security film and the film will either keep its form to the frame or just collapse in a pile. The glass will be contained and injuries from flying glass will be minimized if not eliminated. Reports of serious glass-related injuries in the U.S. can exceed 150,000 annually. According to the US army corps of engineers, this film is referred to as "Fragment Retention" or "Anti Shatter" film.
