What is a druggist fold commonly used for?

The druggist fold is a technique specifically designed for packaging trace evidence, such as fibers, hairs, or small particles, in a way that minimizes the risk of contamination and loss of the evidence. This fold creates a secure pocket that holds the sample tightly, helping to preserve its integrity during handling and transportation.

Using a druggist fold is particularly important in forensic contexts because trace evidence can be easily lost or contaminated if not properly secured. The method allows for the evidence to be collected and stored in a way that maintains the chain of custody and ensures that it can be analyzed accurately later. This is why it is essential for law enforcement and forensic professionals to employ this method when dealing with delicate or small items.
