Each of our new Evidence Security
Bags has tamper-evident designs on it to indicate if the evidence is still
secure. These bags are leak-proof and are made of .4 mil thick,
tear-and-puncture-resistant plastic. The adhesive closure is extremely
strong and there are printed lines on top of the blue band. If anyone tried
to open the bag by pulling on the glue band, the lines will distort.
There are curly border lines all around the other three sides. If someone
cuts one of these sides and tries to heat seal it again, the curly border
lines will show tampering by being shortened or distorted.Each bag has a
chain-of-custody/evidence label printed on it in blue lines on a white
background. By being printed directly on the bag, there is no need for a
stapled-on tag which may fall off or be torn off. It is easy to write on the
bag with a ball-point pen. Most of the front panel is covered with the white
label to provide plenty of writing space, but you can still see the evidence
clearly through the back of the bag.
The tear-off edge of the bag and the bag itself have matching serialized
control numbers. The top edge is removed by the person sealing the bag and
kept as a "receipt." Your agency might want to initiate a policy whereby the
person booking evidence turns in the receipt, stapled to a report form
indicating the circumstances involving the collection of the evidence. The
serialized control numbers can be checked and confirmed at any time to help
prove the integrity of the evidence.
