Numbered Plastic Seals
Plastic Security Seals
Numbered plastic seals for custody handoffs, metering, and tamper indication.
Plastic security seals are the workhorse of the HSA + Trailio custody stack. They are uniquely numbered, scan-readable, and applied at every handoff - bag closing, meter reading, vehicle sealing, trolley locking. Their role is to make every transfer visible.
Product overview
What this physical product is
HSA plastic seals include beaded tail, strap tail, smooth tail, fixed length, padlock, and meter seal variants. Each seal carries a unique serial number, optional barcode, and custom branding. Materials include polypropylene, nylon, and ABS - chosen by tensile strength and application.
Selection & deployment
Select the product, substrate, closure, identifier and workflow for the operating environment. Physical products provide closure or tamper evidence; digital identity, event records and verification require a compatible Trailio deployment.

Capabilities
What this product does
Each capability maps to a Trailio digital surface - authentication, custody, verification, or analytics.
-
Unique serial & barcode
Every seal carries a unique serial number and optional barcode, scanned at the moment of application.
-
Variants for every application
Beaded tail, strap tail, smooth tail, fixed length, padlock, and meter seal variants cover bag, vehicle, trolley, and utility meter applications.
-
Tamper-evident by design
Each seal must be destructively opened - there is no way to remove and reapply.
-
Material choice
Polypropylene for general applications, nylon for high-tensile requirements, ABS for impact and chemical resistance.
-
Custom branding & colour
Seals can carry corporate logos, sequential numbering patterns, and stock or custom colours.
-
Sub-second scan registration
Standard barcode formats support sub-second scan registration into Trailio at the point of application.
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.
-
Seal applied
A uniquely numbered plastic seal is applied at the custody handoff.
-
Serial scanned
The seal serial is scanned into Trailio; the custodian identity is bound to the seal.
-
Custody
The sealed asset moves through transit; the seal serial is the proof of unbroken custody.
-
Seal broken
At the next handoff, the seal is broken; Trailio logs the event against the new custodian.
-
Audit
Every applied and broken seal serial persists in the Trailio audit trail - defensible in investigation.

FAQ
Frequently asked questions
-
Are plastic seals reusable?
No. Plastic security seals are designed to be tamper-evident by destruction - they cannot be removed and reapplied. This is the property that makes them useful for custody handoffs.
-
What's the difference between plastic and metal seals?
Plastic seals are suited to bag closing, metering, trolley locking, and vehicle door sealing. Metal seals (bolt, cable, strap) are suited to containers, trucks, and high-security applications requiring ISO 17712 certification. Many deployments use both.
-
Can seals carry our barcoding scheme?
Yes. HSA produces seals with custom sequential numbering, custom barcoding, custom colours, and corporate branding.
