General Packaging Tips 

  • Evidence packaging needs to be properly sized to accommodate bar-coding, opening and resealing by crime lab personnel. This packaging should be at least 6" long on one side.
  • Paper bags, plastic zip-type bags and manila envelopes of an appropriate size are all good choices.
  • Plastic bags smaller than sandwich bags are NOT appropriate. 
  • Swab boxes should be packaged inside another paper bag. 
  • Glass containers should be avoided. If necessary, they should be packaged inside another non-breakable container (paint can, plastic container) to prevent breakage. 
  • Evidence that has any biohazardous material on it (blood, etc.) must be clearly marked on the outer packaging with a BIOHAZARD sticker.

Sealing the Evidence

A package is properly sealed if:

  1. It prevents loss, cross-transfer or contamination of the evidence.
  2. Entering the container results in obvious damage/alteration to the container or seal.

The seal must consist of evidence tape, self-sealing evidence bags or heat seals. Please ensure when using evidence tape that the tape completely covers open seams/edges of the container.

Initials or other identification of the sealer (badge number, etc) must be ON or ACROSS the seal.
