Tamper evident bag tape
Coin Security Bag Tape
45mm wide tamper evident security tape for coin and cash bags, strong enough for heavy coin and clear enough to show any interference.
A practical way to improve cash security, deter theft and keep confidence in your cash handling process from the point the bag is sealed.

Tamper behaviour
What happens if the seal is interfered with
The 45mm tape shows clear visible signs of tampering, so it is immediately evident if someone attempts to open the cash bag. The tape is non transferable, so any attempt to remove and reapply it leaves visible evidence.
01
Sealed at preparation
The tape is applied across the bag during cash bag preparation, quickly and without tools.
02
Interference attempted
Removal separates the construction, and the thermochromic ink reacts if heat is used.
03
Evidence revealed
A deep colour change appears in the tape and the bag is marked, and the seal cannot be repositioned.

Built for heavy coin bags
Extra width and strength
45mm wide to give extra strength across the bag, because coin is heavy.
Non transferable
Removal and reapplication cannot be hidden, so the seal stays reliable.
Thermochromic ink
Once triggered, a deep colour change shows in the tape and marks the bag if the tape is removed.
Visible deterrent
A visible tamper evident seal reduces the likelihood of theft or unauthorised access to the cash inside.
Quick to apply
A quick, efficient sealing step in the existing cash bag preparation process.
Supports the audit trail
Each check at an inspection point can be recorded against an intact or breached seal.
Chain of custody
How the seal supports your audit trail
Application
The tape is applied to seal the bag, showing it is intact and secure at the start of its journey.
Transportation
Through transport and handling, the seal reduces the risk of unauthorised access going unnoticed.
Inspection points
At each inspection point, personnel or recipients can verify the integrity of the bag. Signs of tampering or removal indicate a potential breach.
Recordkeeping
Each check creates a record, including date, time and location of the inspection and any action taken.
Final destination
On arrival, an intact seal confirms the bag has not been interfered with in transit.
