Types of Security Seal
VOID security labels
Peel or lift the label and a permanent VOID pattern is left behind on both the label and the surface, so any attempt at removal is obvious and irreversible.
Numbered security seals
Sequentially numbered and barcoded seals let each carton, bag, cage or container be logged against a movement record and reconciled at the other end.
Security tape
Tamper evident tape seals cartons, totes and pallet wraps along the full opening, giving a large tamper indicator where a single label would be easy to bypass.
Bag seals
Permanent adhesive seal strips for security bags and dispatch bags, closing the bag once with no way to reopen it without visible damage.
How VOID Security Labels Work
A tamper evident label is built from two bonded layers with a split adhesive. Applied to a clean surface, it behaves like a normal label. Lift it, and the layers separate: a permanent VOID message stays on the surface and a matching pattern appears on the label itself.
The damage cannot be reversed and the label cannot be reused, so a receiving site can tell at a glance whether a consignment arrived as it left — the same principle used by the seals on our cash security bags and evidence bags.

Who Uses Security Seals
Security Seals FAQ
What are security seals used for?
Security seals prove whether a package, container or bag has been opened between despatch and receipt. They are used across cash handling, logistics, pharmacy, evidence storage and asset control to give a visible tamper indicator and an auditable record.
How do tamper evident labels work?
A tamper evident label uses a split adhesive. When someone tries to peel it, the top layer separates and leaves a permanent VOID or OPENED message on the surface underneath. The label cannot be reapplied without the message showing.
Can security seals be numbered?
Yes. Seals and labels can be sequentially numbered, barcoded or QR coded so each one ties to a specific consignment, route, till or evidence record.
Can you print our branding on security labels?
Yes. Security seals and tamper evident labels can be custom printed with logos, warning text, site codes and colour matching, alongside the numbering and barcode format your systems use.
Do you supply security seals in bulk?
Yes. Security seals, tamper evident labels and security tape are supplied wholesale on rolls and in boxed quantities, with bulk pricing for high-volume and multi-site users.
