Industry
Aviation and Secure Transport
In controlled handling environments, custody is only as strong as the point at which it can be verified. That point is usually a seal.
What to send with your enquiry
- Bag or package format and construction
- Handling and custody process
- Security response required
- Whether heat indication and face cuts are needed
- Volume and supply frequency
Industry context
Aviation and secure-transport applications require packaging that shows whether it was interfered with between controlled handover points. Standard VOID material is used in aviation packaging applications, and security-bag tape constructions apply where the format is a sealed bag rather than a labelled carton.
Duty-free, cash-in-transit and evidence-bag applications share the same underlying requirement: the seal must produce evidence that survives resealing, so a chain-of-custody check has something objective to record.
Where the construction calls for it, security face cuts increase the visible evidence a removal attempt leaves, and applicable constructions can include a heat indicator to expose heat-assisted attempts.
What makes this difficult
Verifying custody at handover
Each handover point needs an objective indicator of whether the package was opened since the last check.
Seals that can be lifted cleanly
A seal that reapplies without evidence provides no security value. VOID transfer and face cuts make a clean lift substantially harder.
Heat-assisted interference
Heat is a common method for lifting a seal without obvious damage. Applicable constructions include an indicator that exposes it.
Format varies by application
Duty-free, cash and evidence applications each use different bag constructions and require the tape to be configured accordingly.
Attributes that matter here
These are the properties that decide whether a material works in this sector — and the ones worth being specific about when you enquire.
- Evidence that survives an attempt to reseal
- Security face cuts to increase visible evidence
- Heat indication on applicable constructions
- Custom messaging for chain-of-custody identification
- Constructions supplied to bag manufacturers rather than as finished bags
Solutions that apply
A starting point, not a specification. Final suitability should be confirmed through technical discussion and application testing.
