Police evidence bags are critical tools in preserving the integrity of crime scene evidence. Designed to be tamper-evident, durable, and traceable, they support the chain of custody from collection to courtroom. Whether plastic or paper, choosing the right bag ensures proper protection, prevents contamination, and upholds evidentiary value. Learn how law enforcement uses them—and why quality matters.

Biological evidence is fragile. The best packaging preserves DNA, prevents contamination, and proves chain of custody. Use breathable paper for damp/drying stains; leak-proof, tamper-evident specimen bags for liquids or transport; and plastic only for fully dried items or sealed primary containers. Seal once, sign/date across the seal, label completely, and store at proper temperature. Purpose-built bags like ADSURE’s meet biohazard and 95 kPa needs.

Tamper-evident security bags with RFID combine physical seal integrity and digital traceability. Embedded RFID chips record every handover while tamper-evident seals provide visible proof of interference. These smart bags prevent cloning, skimming, and data leaks, offering dual protection for banking, law enforcement, and medical custody chains where integrity and accountability are critical.
