Description
Packs Protect “The Banker” 6″ x 11″ is a heavy-duty, tamper-evident security bag designed for the secure transport and storage of cash, valuable documents, and high-value items in a format that clearly shows evidence of any attempted opening. We have been stocking Packs Protect security products since 2017 to serve the practical needs of cash-handling businesses, and The Banker in the 6 x 11 inch size is the standard format for securing daily cash takings, important documents, and valuable items in a way that provides visible tamper evidence and a clear chain of custody.
Why Tamper-Evident Bags Are Essential for Cash and Document Security
Standard envelopes and bags provide no evidence of unauthorised opening — they can be carefully resealed without any visible sign of interference. Tamper-evident security bags like The Banker use a permanent adhesive closure that cannot be opened and resealed without leaving clear, irreversible evidence of tampering — the security strip changes colour, tears, or leaves a visible residue pattern on both the bag and the flap if the seal is broken. This visible evidence is the foundation of cash handling security — it deters opportunistic tampering because anyone who opens the bag cannot conceal the fact, and it provides clear evidence of any security breach if one occurs. The 6 x 11 inch size accommodates standard UK banknotes, folded documents, and standard banking paying-in envelopes, making it the right size for most daily cash deposit applications. The sequential serial numbering on each bag creates an audit trail for cash handling procedures.
How to Use Packs Protect The Banker Security Bags
Count and verify the contents before sealing. Record the bag’s serial number in your cash handling log. Fold the contents neatly into the bag, then remove the release liner from the adhesive strip and press the flap firmly onto the bag body, applying firm, even pressure along the full width of the seal. Write the date, amount, and authorised signature in the spaces provided on the bag face. Store or deposit as required. Inspect the seal on receipt — any evidence of tamper response should be investigated and documented before the bag is accepted into the chain of custody.
