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. These all-in-one bags are waterproof, tear- and puncture-resistant, printable and include tamperproof seal. No other evidence bag offers greater integrity, security and convenience. Made of heavy-duty, 3.2-mil-thick, multilayer, coextruded polyolefin film. The IEB4000 is 7.5" and offered in sets of 100 and 500. All IEB Series Bags are now individually numbered and bar coded!
