Product overview
Tamper-evident PET tape is a security sealing tape designed to provide clear, visible evidence when a carton, parcel, bag, document or container has been opened or disturbed. The tape uses a PET film backing with a water-based pressure-sensitive adhesive and a security release structure that produces a VOID message, OPENED mark or custom pattern on the surface, the tape or both depending on the transfer type.

Key features:

• Visible tamper evidence: VOID/OPENED or bespoke pattern appears on removal.
• PET film backing: stable handling for manual and machine application.
• Multiple transfer types: total-transfer, partial-transfer, non-transfer.
• Custom printing: security messages, logos, warnings and handling instructions.
• Custom roll formats and winding options for automated lines.

Applications:

• E-commerce and retail carton sealing
• Courier, logistics and returns management
• Confidential envelopes and document seals
• Electronics and spare-parts packaging
• Security bags, containers and high-value shipments
