When packaging wet materials, what should be used?

Using plastic for packaging wet materials is considered the best practice because it offers a moisture-proof solution that effectively prevents leakage and contamination. Plastic bags or containers can seal tightly, preserving the integrity of the wet material and protecting it from external elements. This is particularly important in forensic and investigative contexts, where maintaining evidence in its original state is crucial for analysis and presentation in court.

Other materials, like cardboard and paper, are not suitable for wet items as they can become soggy and disintegrate, compromising the evidence. Wood could absorb moisture and is not a practical choice for packaging due to its porous nature and potential for harboring contaminants. Therefore, plastic stands out as the most effective option for this purpose, given its waterproof qualities and ability to maintain the condition of the materials being packaged.
