Capabilities
What this product does
Each capability maps to a Trailio digital surface - authentication, custody, verification, or analytics.
-
VOID / OPENED tamper indicator
The bag surface reveals an irreversible VOID or OPENED message if heat, freezing, or solvent attack is attempted.
-
Freon / freezing indicator
A dedicated indicator discolours if the bag is frozen - defeating a common cash-in-transit tamper technique.
-
Heat & fugitive ink indicator
A heat-sensitive patch and fugitive ink pattern expose attempts to open the bag with steam or solvents.
-
Serial, barcode & perforated receipt
Each bag carries a unique serial, barcode, and a tear-off receipt that becomes the custodian's evidence of acceptance.
-
Transparent & opaque variants
Transparent variants allow visual inspection without opening; opaque variants protect confidentiality of contents.
-
70 / 80 micron stock
70 and 80 micron film thicknesses are available in stock; bespoke thicknesses are produced to order.
Trailio Integration
How this product integrates with Trailio
Every physical event - a seal applied, a label scanned, a bag closed - becomes a verified digital record inside the Trailio audit chain. The workflow below illustrates the operational handshake.
-
Contents placed & sealed
Cash, documents, or evidence are placed inside; the bag is sealed and the serial is scanned.
-
Custodian registered
Trailio binds the bag serial to a custodian identity at the moment of sealing.
-
In transit
The bag moves through custody handoffs; each transfer is scan-confirmed.
-
Tamper event
If VOID, freezing, or heat indicators are triggered, Trailio logs the tamper event against the bag serial.
-
Acceptance & close
The receiver scans the bag serial and accepts custody; Trailio closes the chain with a verified endpoint.

FAQ
Frequently asked questions
-
What's the difference between single-use and reusable bags?
Single-use plastic security bags are destroyed on opening - the tamper evidence is permanent. Reusable bags (see Heavy Duty Canvas Bags) are designed for repeated use with replaceable seal chambers. Single-use bags are typical for one-way cash, document, and evidence transit.
-
Can I customise the bag size and print?
Yes. HSA offers customisation on dimensions, thickness, multi-colour print, write-on panels, and tamper-evident feature set.
-
Do bags have freezing protection?
Yes. Freon and freezing indicators are available on the tamper-evident feature set, alongside heat and fugitive ink indicators.
-
Can a single bag carry multiple evidence receipts?
Yes - perforated serial receipts can be configured to support multi-party acceptance workflows.
