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"). This All-in-One bag is waterproof, tear- and puncture-resistant, printable and include a tamperproof seal. No other evidence bag offers greater integrity, security and convenience. It is made of heavy-duty, 3.2-mil-thick, multilayer, coextruded polyolefin film.
