What is the appropriate packaging for dry objects?

• A. Brown paper sack
• B. Cardboard box
• C. Envelope
• D. Plastic bag

Answer: (A)

Breathable packaging is essential for dry objects because it prevents moisture buildup that can promote mold, degrade materials, or alter the condition of the evidence. A brown paper sack is best because it is porous enough to vent moisture while still containing the material, reducing the risk of condensation and preserving dry traces such as powders or fibers. It also minimizes static and is easy to seal and label for proper handling. Other options either trap moisture (plastic bags), are not suitable for dry contents (envelopes, which are typically for documents or small items), or lack the breathable containment that helps keep dry evidence intact (cardboard boxes).
