Paper Evidence Bags

Paper evidence bags are essential for storing and transporting dry or biological materials because they allow moisture to escape. This prevents mold growth and DNA degradation, ensuring the integrity of the sample. Law enforcement and forensic teams use paper bags to maintain evidence quality while meeting chain of custody standards.

Paper evidence bags are breathable and ideal for items like clothing, documents, or biological samples that may contain moisture. Plastic evidence bags are better suited for non-biological materials or trace evidence that requires a sealed environment. Using the correct type helps prevent contamination and ensures compliance with forensic best practices.

After placing the evidence inside, fold the top edge over twice, apply evidence tape across the fold, and write the initials, date, and case number across the seal. This tamper-evident method ensures proper chain of custody and prevents unauthorized access. Always store sealed bags in a dry, secure environment.

EVIDENCE keeperbag™ paper bags include pre-printed chain of custody areas, reinforced seams, self-sealing closures, and heavy-duty kraft construction. These features meet law enforcement standards for secure handling, labeling, and traceability during evidence storage and transport.
