Secure box tape

Tamper evident box tape for sealing cartons

Box tape that makes an opened carton obvious. When the tape is lifted, a VOID message transfers and stays split between the tape and the box — so the person receiving the carton can see it was interfered with, not just guess.

Made in the UK, supplied on rolls for hand dispensers and for automatic case sealers. If you are not sure which construction suits your board, film or freezer temperature, send us the pack and we will specify it.

What happens when it is disturbed

Intact, interfered with, evidence

Tamper evident tape does not stop a carton being opened. It changes what an opened carton looks like, so interference is discovered at goods-in instead of at the customer.

When to use it

  • Outbound cartons that pass through more than one pair of hands — 3PL, courier, cross-dock, export.
  • High-value or easily resold contents where partial pilferage is the loss, not the whole box.
  • Shipments where you need a defensible answer to “was this box opened before it reached us?”
  • Lines already sealing with tape, where you want security without changing the process or the machine.

When not to use it

  • Where the closure is not a taped seam — a bag, pouch or tote usually needs a tamper evident label instead.
  • Where the surface is dusty, waxed, oily or heavily recycled board — transfer can be inconsistent; test first.
  • Where the requirement is proving an item is genuine rather than proving the pack is unopened — that is authentication, and it is a different job. Tape evidences the seal, not the contents.
  • Where the carton is opened and resealed as a normal part of the process — you will generate false positives.

Specification

What to specify when you order

Width27mm to 240mm. 48mm and 50mm are the common carton-sealing widths; wider tape suits large-format or double-seam cartons.
Roll length10m to 900m. Short rolls for hand dispensers, long rolls for automatic case sealers.
SubstratePaper or film. Paper suits recyclable single-material cartons; film suits damp handling and colder stores.
MessageVOID, OPENED, SEALED FOR YOUR PROTECTION, or your own wording. Multilingual wording where the pack crosses borders.
Residue behaviourFull-transfer or part-transfer, depending on whether you want the message to stay on the carton.
SerialisationOptional sequential numbers, barcodes or QR, so a seal can be recorded against a consignment.
ApplicationHand dispenser or automatic case sealer — tell us the machine, because it constrains core size and length.
TemperatureApplication and storage temperature range, including chilled and frozen.

What to test before you commit

01

Your own board

Test on the exact carton you use, including recycled and coated grades. Transfer quality is a function of the surface, not just the tape.

02

Your line speed

Run it through your case sealer at production speed. Check the seam is fully wetted out and the tail does not lift.

03

Your worst journey

Test after the temperature, humidity and handling the pack actually sees — chilled stores and long export legs change behaviour.

04

Defeat attempts

Try to open and reseal it the way a determined person would, including heat and slow peeling. Record what the evidence looks like.

05

Goods-in recognition

Show a voided carton to the people who will receive it. If they cannot tell in three seconds, the message or colour needs changing.

06

Recyclability

If the carton is sold as recyclable, confirm the substrate choice fits your waste stream before you standardise.

Let us specify it against your carton

Send the carton, the tape you use now and a note on the journey. We will tell you what construction gives usable evidence — and where tape is the wrong answer.
