What is the primary purpose of proper evidence packaging?

The primary purpose of proper evidence packaging is to prevent evidence contamination and loss. Proper packaging is critical to maintaining the integrity of the evidence from the crime scene through to the courtroom. If evidence is contaminated, it can lead to unreliable results in analysis, which may compromise the entire investigation and any subsequent legal proceedings. This safeguarding process includes using the appropriate materials and techniques that are designed to protect evidence from environmental factors, biological degradation, or tampering.

While securing evidence for transport, enhancing the investigation process, and making evidence visible for inspection are important aspects of handling evidence, they are secondary to the fundamental goal of preserving the original state and reliability of the evidence. Without meticulous attention to preventing contamination and loss, the overall effectiveness of any investigative efforts can be severely undermined.
