Bolt-Style Tamper-Seal Tags

Push these tags through hasps on cabinets, truck trailers, cargo containers, and other heavy duty equipment. With an average breaking strength of 3,000 lbs., they are more secure than other tamper-seal tags.

Push-Through Tamper-Seal Tags

These seals cannot be removed without cutting or leaving visible evidence of tampering—they will rip the cardboard if pulled out.

Tamper-Seal Labels

When removed, the adhesive separates from the backing to reveal the words "Open" and "Void".

Tamper and Vibration Detection Paint

High-Visibility Tamper and Vibration Detection Paint

Choose from highly visible fluorescent colors.

Tamper and Vibration Detection Paint

Apply directly to equipment for easy and economical detection. When paint dries it becomes brittle and cracks from any movement caused by tampering or vibration.

Packaging Tape

Tamper-Evident Packaging Tape

Get peace of mind when packaging high-value and confidential items—this tape indicates a package has been opened.

Tamper-Evident Water-Activated Packaging Tape

When tape is removed, a red layer stays behind to indicate the package has been opened.

Tamper-Evident Bags

Securely transport confidential documents, money, and other materials—these bags show clear signs of tampering if they have been opened. Unlike other bags with unreliable adhesives and burdensome keys, these are sealed with locking pins or tags.

Tamper-Evident Tapered Plugs

Often used on gas cylinders, these plugs cinch and lock tightly around valve heads to block the ports—they must be cut off making it clear if the cylinder has been tampered with. The plugs are tapered to fit a range of hole diameters.
