(2) Sacks and bags-All sack-like containers should be sealed by folding down the flap of the sack across the top and placing a continuous piece of 2 inch tape, 3M Brand #3750 or equal, across the fold and around the sack edges.

(3) Envelopes- The top unsealed flap of the envelope should be completely sealed along the seam using two inch tape, 3M Brand #3750 or equal, or with evidence tape.

(4) Cans and buckets with lids-One continuous piece of evidence tape across the top and down the sides of the container or two separate pieces of evidence tape across from each other shall be used to seal all such containers. Clear adhesive tape should not be used.

(5) Kits-Sexual assault kits, blood alcohol kits and other purchased evidence submittal kits are acceptable with the seals provided by the kit manufacturer.

(6) Evidence not sealable in a container-Such evidence shall be properly sealed by taping and initialing a seal over the area of interest to be tested. If such seal would obliterate, destroy, or alter the evidence, then identify the area of interest by circling or marking nearby.
