Trusted Evidence Bag Sealers for Law Enforcement

When law enforcement agencies need to protect critical evidence, they rely on dependable, tamper-evident sealing technology. For years, police departments, state agencies, crime labs, and forensic teams have trusted PAC Machinery’s Sealmaster Magneta impulse heat sealers to create permanent security seals that help preserve the chain of custody and protect the integrity of evidence.

According to New York State Trooper Scott Shepard:

“We come in contact with materials that are hazardous and need to be sealed to an evidentiary standard, and our standard is to have an embedded security heat seal.”

When asked why the department selected Sealmaster Magneta 621 MG sealers, Trooper Shepard explained:

“We have several of these machines and have used them for many years. They have always worked to standard and have an excellent track record for reliability.”

Tamper-Evident Evidence Sealing You Can Trust

PAC Machinery’s Sealmaster Magneta impulse heat sealers create permanent, tamper-evident seals by embedding a custom security imprint directly into the heat seal. This unique code seal provides a clear visual indicator if an evidence bag has been opened or compromised.

The process uses precision impulse heat sealing technology to permanently bond thermoplastic evidence bags while simultaneously imprinting department-specific text, numbers, or identification codes into the seal. The result is a secure, durable seal that cannot be duplicated without authorized equipment.

If an evidence bag is presented without the embedded code seal, it may indicate that the original seal was removed and the bag resealed, raising concerns about possible tampering and jeopardizing the admissibility of evidence.

How Code Seal Technology Works

Sealmaster Magneta impulse heat sealers use a precision Nichrome heating element to deliver the exact combination of heat, pressure, and sealing time required for consistent evidence bag sealing. A custom laser-etched sealing bar permanently embeds the agency’s identification into every seal during the sealing cycle.

This process creates:

• Permanent tamper-evident security seals
• Embedded department identification
• Reliable evidence bag sealing
• Consistent chain-of-custody protection
• Long-lasting, repeatable performance

Proven Reliability for Critical Evidence

From hazardous materials to criminal investigations, law enforcement agencies depend on PAC Machinery’s evidence sealing equipment because reliability isn’t optional—it’s essential.
