What should be used to wrap and package recovered tools that contain contamination?

The appropriate method for wrapping and packaging recovered tools that contain contamination is using paper to prevent contact with other surfaces. This choice is vital because paper allows for breathability, minimizing the risk of trapping moisture which could lead to further contamination or degradation of the evidence. Furthermore, paper is less likely to create static electricity compared to plastic, which can dislodge trace evidence and compromise the integrity of the collected samples.

Using plastic bags, while they might provide an airtight seal, can inadvertently create a microenvironment where moisture and contaminants are trapped, compromising the evidence. Bubble wrap, although it offers cushioning, does not provide the necessary protection against contamination from contact with other surfaces. Cloth might absorb moisture but does not offer adequate protection from contamination and can also leave lint or fibers that could interfere with evidence analysis. Therefore, wrapping tools in paper is the most reliable method to preserve their integrity during transport and storage.
