Introduction to Tamper Evident Seal Labels VOID Tamper Proof Labels
Tamper Evident Seal Labels VOID Tamper Proof Labels are the industry-standard mechanism for providing visible, irrefutable proof that a product, package, or enclosure has been opened or accessed after the point of sealing.
The VOID mechanism operates through a precisely formulated adhesive-and-ink system: the label face carries a hidden security layer that, when the label is subjected to any peeling force, transfers permanently to the substrate surface in the form of a clearly legible “VOID” message, while the corresponding complementary pattern remains visible on the underside of the removed label fragment.
Because the VOID impression is embedded in the substrate surface and the label cannot be de-transferred or reversed, these tamper-evident seal labels provide conclusive evidence of access that cannot be concealed by a third party.
VIZLENT manufactures Tamper Evident Seal Labels VOID Tamper Proof Labels across a range of face material and adhesive combinations to suit the full spectrum of sealing substrates encountered in product security applications.
- Silver polyester VOID film provides high visual contrast for the revealed VOID pattern and a premium security appearance.
- White polyester VOID film is preferred where the label must carry significant printed content such as barcodes, serial numbers, or regulatory text.
- Transparent VOID film allows the substrate colour or branding to show through while maintaining the full tamper-evidence mechanism — a configuration favoured for consumer products where label aesthetics are important. Custom die-cut shapes allow the label to bridge packaging seams, cover fasteners, or span closure interfaces with precision.

Frequently Asked Questions
Yes. VIZLENT customises Tamper Evident Seal Labels VOID Tamper Proof Labels with company logos, brand colours, custom VOID message text, and variable data including sequential serial numbers, barcodes, and QR codes. Fixed artwork elements are printed during production; variable data can be factory-printed in sequence or supplied on blank overprint-ready rolls for in-house thermal-transfer printing. We provide a digital artwork proof before production begins, and a physical pre-production sample can be arranged for approval.
No. The VOID impression transferred to the substrate surface by VIZLENT’s tamper-evident labels is a permanent ink transfer that is fully bonded to the substrate and cannot be removed by rubbing, erasing, or overpainting without visibly damaging the substrate surface itself. Attempting to cover the VOID impression with another label will be evident on close inspection, and since the security serial number of the original label no longer matches a new label applied over the tampered area, any audit or returns management process that checks serial numbers will identify the discrepancy.
The MOQ for custom-printed Tamper Evident Seal Labels VOID Tamper Proof Labels is 1,000 labels per design and size. For customers who need labels quickly for an immediate programme, VIZLENT maintains semi-finished stock of selected standard VOID label sizes in silver and white PET that can be finished and dispatched within 3–5 working days for simple serial number overprinting. Contact our sales team with your required size, quantity, and print content to confirm stock availability and lead time.
VIZLENT’s VOID tamper-evident labels use a high-tack permanent acrylic adhesive that is formulated to activate the VOID transfer mechanism at the very earliest stage of any peeling attempt, before a potential tamperer can develop a controlled peel front. The VOID transfer layer is designed to release from the label face and transfer to the substrate under the shear forces generated even by very slow peeling. There is no peel angle, speed, or temperature combination under which the label can be removed without activating the VOID mechanism on a compatible substrate.
Yes. VIZLENT can supply Tamper Evident Seal Labels VOID Tamper Proof Labels with factory-printed sequential serial numbers, Code 128 barcodes, or QR codes that can be scanned at the point of application to register each sealed unit in your ERP, warranty management, or product authentication system. We provide the serial number data file in CSV or Excel format alongside the label shipment for system import. For returns management, a scan of the label on return immediately links to the original sale or registration record, and the physical condition of the label confirms whether tampering has occurred.
