What is considered the preferred method for packaging evidence?

The preferred method for packaging evidence is the use of paper or paper board. This choice is favored primarily because paper allows for breathability, which helps to prevent the accumulation of moisture that could lead to mold or degradation of certain types of evidence, such as clothing, biological samples, or documents. Additionally, paper is less likely to create a static, which can be beneficial for preserving trace evidence like hair or fibers.

Using paper also allows for better labeling and documentation, as evidence can be written on directly or securely fastened to the packaging. When utilizing paper or paper board, it is important to ensure that all evidence is packaged carefully to maintain its integrity and to prevent contamination.

In contrast, while plastic bags might seem convenient, they can trap moisture and lead to the deterioration of the evidence inside. Cardboard boxes are often used for bulkier items but lack the breathability that paper provides. Glass containers are suitable for some items, but they carry risks such as breakage and can also create issues in terms of weight and handling. Therefore, while there are various methods to package evidence, paper or paper board remains the most preferred for its ability to protect and preserve the integrity of different types of evidence.
