Thanks for your great question! First, you can attempt to double bag in paper. Also, it's important to note that you can package in plastic to transport evidence to lab (providing this is will be done within hours, not days). Once the evidence is in the lab, allow it to air dry (preferably in a clean hood), then package in paper for long term storage.
What if the blood is so wet that it seeps through the paper?
