Bulletproof Film 336
Bulletproof film 336- is a human life protection agent from planned attacks such as terrorism, explosion or assassinations. It stops bullet and explosion from glass penetration and protects human life or property. Resistance capability depends much on type of armor, bullet, thickness of glass and number of layer. with that siad...our glass is 1/8 to maybe at the most 3/16 thick...plus a big safty issue..would be in the event of an accident, if that film was on the glass...how would you get out?????
