THIS MATERIAL IS RESISTANT TO HANDGUN ROUNDS (UP TO ITS STATED THREAT LEVEL) AND KNIFE PUNCTURES. HOWEVER, A THIN WEAPON SUCH AS AN ICE PICK CAN PUNCTURE IT, AND BLUNT TRAUMA MAY RESULT FROM BULLETS. BLUNT TRAUMA IS, HOWEVER, THOUGHT TO BE SUPERIOR TO PENETRATION BY A BULLET. THIS FILM MIGHT BE USEFUL TO POLICE DEPARTMENTS INTERESTED IN USING LIGHTWEIGHT BODY ARMOR.
