Container for trace evidence

Container for trace evidence

• A. Envelope
• B. Bag
• C. Bindle
• D. Vial

Answer: (C)

Handling trace evidence requires a container that prevents loss or contamination while keeping the item identifiable for testing. A bindle is a folded piece of paper used to wrap a tiny item—such as a fiber, hair, or powder—creating a discrete, inert barrier between the evidence and other packaging. This simple wrapper reduces cross-contamination, dries or preserves fragile items, and minimizes the chance of residues transferring to or from other contents. It also keeps the evidence compact and easy to store, so it can be labeled and tracked through the chain of custody more reliably. While envelopes, bags, and vials can be used in some cases, they are more prone to moisture issues, cross-contamination, or difficulty handling for very small traces. The bindle is specifically suited to preserving the integrity of trace evidence during collection and transport.
