Law Enforcement & Forensic Security Solution

Preventing Evidence Tampering & Chain of Custody Breaches

Evidence handling procedures are only as strong as the packaging behind them. If a seal can be opened and reclosed without leaving a mark, or if a bag tears during storage, the chain of custody breaks. In court, that gap is exactly what a defense team looks for, and it can undo months of investigative work.

Shosky produces tamper-evident bags, security tape and chain-of-custody labels for police departments, forensic laboratories and evidence units. Each bag carries a permanent tamper indicator and a serial number, so officers and lab technicians always have a clear, checkable record of when a seal was applied and whether it has been touched since.

FAQs

Common questions from law enforcement and forensic teams sourcing tamper-evident packaging.
Quote Now

A: Yes. We print sequential serial numbers and barcodes on both the bag and tape, so your intake system can match a physical seal to a specific case record.

A: Full-transfer tape leaves the whole “VOID” message on the bag when removed. Partial-transfer leaves marks on both the tape and the bag. Non-transfer keeps the bag surface clean but hides a message inside the tape itself.

A: We can supply leak-resistant, puncture-resistant film and add biohazard warning printing on request. Send us your specimen handling requirements and we will confirm the right material.

A: Yes. We handle agency logos, case number and officer ID fields, barcodes, QR codes and warning text, and will send a digital proof before production starts.

A: This depends on bag size, film thickness, and whether new printing plates are needed. Custom orders usually take 10 to 15 business days after artwork approval. Send us your specifications for an exact quote.
