The Safariland 5 x 8" Evidence Security Bags feature a special, extremely strong tamper-indicating adhesive that, once opened, will not reseal. The word "EVIDENCE" is printed around the borders of the bag. If the bag is opened, then heat-sealed closed, the words will shorten or distort. The bags are leak-proof and made of 4 mil thick tear and puncture-resistant plastic. Each Evidence Security Bag has a pre-printed chain-of-custody label on it with blue lines on a white background. It is easy to write on the bag with a ball-point or felt-tip pen.
The majority of the front panel is covered with a translucent white, which provides plenty of writing space. However, the back and the edges remain completely clear so that evidence is still easy to see. Each bag features a unique control number. The top edge is perforated and has a matching control number. The top edge can be removed by the person sealing the bag and kept as a receipt. The tear-off receipt also includes an area to write information pertaining to the evidence.
