When packaging evidence, what type of containers should be avoided for fibers?

When packaging evidence such as fibers, plastic bags should be avoided. This is because fibers can produce moisture, and the sealed environment of a plastic bag can trap humidity, leading to potential degradation or contamination of the fibers. Unlike paper, which is breathable and can absorb some moisture, plastic does not allow for air circulation and can create an environment that may promote mold or other forms of deterioration.

In contrast, other types of containers, like paper bindles, glass jars, and cotton envelopes, are generally more suitable for storing fibers. Paper bindles, for instance, allow for airflow, reducing the risk of moisture retention, while glass jars provide a secure and contaminant-free environment that also protects delicate evidence from being damaged or lost. Cotton envelopes are breathable and help maintain the integrity of the fragile fibers contained within. Thus, the packaging choice is crucial in preserving the quality and evidentiary value of the fibers.
