What is a tamper-evident evidence bag?A tamper-evident evidence bag is a plastic bag with a high-security adhesive seal that bonds permanently when closed, so any attempt to peel, tear, or reopen it leaves visible damage.

What sizes do plastic evidence bags come in?Prism Pak evidence bags run from 4 x 6 inches for small items such as USB drives, shell casings, and swabs, up to 18 x 24 inches for clothing, weapons, and bulky evidence.
