PET Tamper Evident Tape for Security Packaging
Tamper-evident tape is a security sealing tape designed to show visible evidence when a carton, parcel, bag, or container has been opened or disturbed.
It uses a PET film backing with a pressure-sensitive adhesive and a security release structure. After removal, a VOID message, warning text or customized pattern may appear on the surface, the tape or both, depending on the selected construction.
It is also known as security tape, VOID tape or tamper-evident sealing tape.

Tamper Evident Tape FAQ
What is tamper evident tape used for?
Tamper evident tape is used to show visible evidence when a carton, parcel, bag, document or container has been opened or disturbed. After removal, a security message or permanent visual change may appear on the tape, the application surface or both, depending on the selected tape structure.
How does tamper evident tape show unauthorized opening?
The tape contains a security release layer that reacts when the tape is removed. A VOID message, warning text or hidden pattern may then become visible. The exact result depends on the transfer structure, adhesive, application surface, pressure, temperature and bonding time before removal.
What is the difference between total, partial and non-transfer tape?
Total transfer tape leaves the complete security message on the application surface. Partial transfer tape leaves evidence on both the surface and the removed tape. Non-transfer tape mainly changes the appearance of the tape itself, with limited or no message left on the application surface.
Does the tape leave a VOID message on the surface?
It depends on the selected construction. Total-transfer and partial-transfer tapes can leave a VOID message or security pattern on the application surface. Non-transfer products mainly show the visual change on the tape itself. The required result should be confirmed before sampling and bulk production.
Which surfaces are compatible with tamper evident tape?
Tamper evident tape may be used on cartons, coated paperboard, plastic bags, plastic containers, painted metal, glass and smooth panels. Performance can vary on recycled board, rough surfaces or low-surface-energy plastics. Testing with the actual packaging surface is recommended before order confirmation.
Can the security message and printing be customized?
Yes. The hidden message may use standard text such as VOID or OPENED, or a customized logo, warning message or repeating pattern. Surface printing, tape color, roll size and packaging may also be customized. Available options depend on the product structure, artwork and order quantity.
How long does the tape need before the security feature activates?
Activation time depends on the adhesive, surface, temperature and tape construction. Some products show evidence shortly after application, while others require a longer bonding period for consistent message transfer. The recommended dwell time should be confirmed through sample testing under the actual packaging conditions.
What information is required for a quotation?
Please provide the application, packaging surface, required transfer type, security message, tape color, printing design, roll width, roll length, core size, quantity and destination country or port. Photos or samples of the application surface can help us recommend a suitable tape structure and adhesive.
