The manner in which evidence is stored and protected can often mean the difference between conviction and acquittal. With this in mind, Sirchie introduces the integrity evidence bag (7.5x10.5"). These All-in-One bags are waterproof, tear- and puncture-resistant, printable and include a tamperproof seal. No other evidence bag offers greater integrity, security and convenience. It is made up of heavy-duty, 3.2-mil-thick, multilayer, coextruded polyolefin film.
