Custom Tamper-Evident Security Labels
Custom tamper-evident security labels designed to reveal unauthorized opening, removal or replacement. Choose total-transfer or partial-transfer VOID labels, destructible films, security cuts, serial numbers, QR codes and holographic features. Supplied in custom sizes, shapes, rolls or sheets for packaging, electronics, cosmetics, pharmaceuticals, logistics and brand-protection applications.
Custom Tamper-Evident Security Labels
Custom tamper-evident security labels provide visible evidence when a package, component or enclosure has been opened, removed or replaced. SZKAYU manufactures security labels to match your required tamper response, application surface and production process. Options include total-transfer and partial-transfer VOID films, destructible materials, security cuts, serial numbers, QR codes, variable data and holographic features.
Unlike standard decorative labels, a tamper-evident label must balance the face material, adhesive and release construction. The correct combination depends on whether the label is applied to glass, metal, coated cartons, rigid plastic or a low-surface-energy material such as PP or PE. We review the substrate and use environment before recommending a construction, helping buyers avoid labels that lift too easily or leave the wrong security message.
For projects that also require optical authentication, explore our security and holographic label solutions or see our custom holographic security labels.
What We Need for a Fast Quote
- Finished label size, shape and order quantity
- Application surface and packaging material
- Required tamper result: total-transfer VOID, partial-transfer VOID, destructible, security-cut or non-transfer
- Artwork, brand colors and any fixed or variable data
- Roll or sheet format, core size, winding direction and machine-application requirements
- Application temperature, service environment and storage conditions
Photos or samples of the application surface are helpful. For demanding substrates, we recommend testing a production-representative sample before the final order.
Choose the Right Tamper-Evident Construction
Total-Transfer VOID Labels
When removed, the security message transfers completely to the application surface. This creates strong, obvious evidence of opening and makes clean replacement difficult. Total-transfer constructions are commonly used for electronics, equipment housings, cartons and high-value products.
Partial-Transfer VOID Labels
Part of the security message remains on the surface while the rest stays visible in the label film. This provides evidence on both the product and the removed label, making it useful for warranty seals, asset control and packaging closures.
Destructible Film Labels
Destructible materials break into small pieces when removal is attempted. They are suited to warranty seals, component labels, inspection points and applications where a label should not be removed intact and reused.
Security Cuts and Frangible Designs
Custom slits, star cuts and segmented die cuts cause the label to tear during removal. Security cuts can be combined with printed branding, numbering and QR codes when a cost-effective tamper indicator is required.
Non-Transfer Security Labels
The hidden message appears in the face film without leaving adhesive text on the application surface. This option is suitable when the surface must remain relatively clean while the removed label still shows clear evidence of tampering.
Materials, Adhesives and Security Features
Available face materials include PET, PVC, destructible vinyl or film, coated paper and holographic film. Adhesive selection is matched to the substrate and application conditions. Common surfaces include glass, painted or bare metal, coated paperboard, PET, HDPE and PP. Rough, curved or low-surface-energy surfaces should be tested before mass production.

Frequently Asked Questions
What is the difference between total-transfer and partial-transfer VOID labels?
Total-transfer labels leave the complete security message on the application surface. Partial-transfer labels divide the evidence between the surface and the removed film. The best choice depends on the required visibility, surface and whether evidence is needed on one or both parts.
Can these labels adhere to PP, PE or textured surfaces?
Yes, but low-surface-energy and textured materials need careful adhesive selection. Please provide the exact substrate or a sample so we can recommend and test a suitable construction.
Can every label have a unique QR code or serial number?
Yes. We can print sequential or database-supplied serial numbers, barcodes, QR codes and variable text. Please provide the data format and verification requirements when requesting a quote.
Can the labels be supplied for automatic application?
Yes. Specify the core diameter, maximum roll diameter, gap, winding direction and labeling-machine requirements. We will arrange the roll layout accordingly.
Can I request samples, and what is the MOQ?
Sample options and minimum order quantities depend on the material, custom security construction and printing process. Standard material samples may be available, while a fully customized sample may require a setup charge.
