Our innovative FRAUDSTOPPER ONE™ bags offer a pressure-sensitive, in-line closure and other high-end security features, making it impossible to open and reseal without showing clear signs of tampering.


  • Manufactured with high-strength, 3-layer, co-extruded film (available in clear and opaque)

  • Exceeds all bank and CIT requirements for tamper-evidence at temperature extremes

  • Available as a customized bag (up to 12” wide)

  • 100% recyclable (Category 4 LDPE)

  • Optional: document pouches, 2-pocket formats, and/or GS1-compliant barcodes

  • Optional: SureTraxx™ deposit bag numbering system, guaranteeing that every bag is numbered in sequence and present in its proper box

Level 4

‘Level 4’ bags provide the highest level of security in the tamper-evident security packaging industry, ensuring that all tampering attempts are clear and easily noticed. Our FRAUDSTOPPER ONE™ technology exceeds all Level 4 standards and protects against:
  • Exposure to extreme heat
  • Exposure to extreme cold
  • Exposure to chemicals and solvents
  • Mechanical attacks



Effects of cold-tampering

Reacts to all cold tampering attempts, generating the appearance of “X” and “VOID” graphics via our proprietary cold-indicating technology

Effects of heat-tampering

Reacts to all heat tampering attempts, generating the appearance of blue honeycombs and dashes – on the center and edges of the tape – via our proprietary heat-indicating technology

Proprietary U-cuts

Produced with undetectable incisions along the tape’s border, promoting tearing and distortion upon any attempt to reopen the bag after it’s sealed shut

Numbers and barcoding

Features high-resolution, scratch and chemical resistant serial numbers and barcodes (1D or 2D) printed with UV-cured ink jet technology, supporting track-and-trace capabilities and preventing duplicate bag replacements

In-line closure

Includes a proprietary, pressure-sensitive sealing mechanism, enabling a consistent, user-friendly sealing process when closing each security bag

Printed liner receipt system

Leverages the adhesive tape liner as the security bag receipt, rendering it impossible to seal the bag shut without first removing and using the receipt

Soluble ink

Utilizes soluble, security graphics below the tape closure that distort and dissolve if exposed to saliva, glycerin, or other liquids/gels

Indented side seals & security printing

Produced with security pouch seals and graphics – indented from the bag’s side – rendering it impossible to slit and reseal the sides without clear signs of tampering

Natural-fold bottom & top construction

Produced with a uniform, folded edge – rather than sealed – rendering it impossible to cut and reseal the bottom and top edges without clear signs of puncturing or slitting

What’s the main difference between your FRAUDSTOPPER ONE™ and FRAUDSTOPPER™ security closures?

Our FRAUDSTOPPER™ and FRAUDSTOPPER ONE™ bags both exceed Level 4 security standards. The fundamental difference between the two security closures is the height and surface area of the adhesive. FRAUDSTOPPER ONE™ has a narrower closure that’s suitable for smaller bag sizes without sacrificing quality.

What is the minimum order requirement for custom bags?

Minimum order quantity for custom bags will vary depending on the size and thickness required. Please contact us and we will put you in touch with one of our Account Managers to guide you through the process of designing your own bag.
