Sirchmark Red Evidence Tape

Sirchmark Red Evidence Tape is the standard chain-of-custody marking solution trusted by law enforcement agencies, crime scene investigators, and forensic professionals across North America. Designed specifically for sealing, marking, and authenticating evidence containers, this red evidence tape provides a tamper-evident barrier that clearly signals when packaging has been accessed or compromised. Used in evidence rooms, crime labs, and field operations, it serves as both a practical security measure and a legally defensible documentation tool in criminal investigations and court proceedings.

The Sirchmark Red Evidence Tape features a matte acetate base engineered to accept written notation via pencil or pen without smudging or degradation—critical for recording case numbers, officer names, dates, and times directly on the tape itself. The permanent, quick-setting acrylic adhesive bonds aggressively to cardboard, plastic, wood, and metal surfaces, resisting removal and effectively deterring unauthorized tampering. Precision perforations spaced at 3/16-inch intervals allow for clean, controlled tearing by hand, eliminating the need for scissors and enabling rapid deployment in high-volume processing environments. The matte finish prevents light reflection that could obscure handwritten documentation during photograph review or courtroom presentation.

Evidence custodians, forensic technicians, and investigative units benefit most from this tape's reliability in maintaining chain-of-custody integrity across the entire evidence lifecycle. Its compatibility with standard evidence boxes, sealed bags, and specialty packaging ensures seamless integration into existing evidence handling protocols without retraining or workflow disruption. The compact 4.3 x 1.95 x 4.2-inch roll format fits easily into field kits, evidence carts, and desk drawers, making it accessible whenever evidence is received, sealed, or transferred between departments. This tape is essential for agencies prioritizing forensic accuracy and legal defensibility in case documentation.
