Printing Banana provides VOID tamper-evident label printing for electronic product seals, warranty labels, document seals, logistics security and product warranty stickers. Quotes depend on size, surface, serial numbers, QR codes or barcodes.
Suitable for electronic product seals, warranty labels, document seals, logistics security and product warranty stickers. Once peeled off, they can leave a VOID mark or other evidence of tampering, making it easy to tell whether a product, package or document has been opened. When enquiring, please provide the intended use, application surface, size, quantity and whether serial numbers / QR codes / barcodes are required.
Suitable for electronic products, accessories, repair seals and warranty labels. The application surface, seal position, size and whether numbering is required must be confirmed.
Suitable for sealing important document envelopes, product boxes, gift boxes or confidential packages. Evidence left after peeling indicates that the seal has been opened.
Suitable for carton seals, logistics security labels and batch management. Serial numbers, QR codes, barcodes or warning text can be included.
Suitable for document seals, general tamper-evident packaging or small test runs. The size, application surface and residual VOID effect should be confirmed first.
The recommended option for electronic products, warranty, logistics and repair applications. A logo, warning text, QR code or barcode can be added, with the scannable size confirmed.
Suitable for warehouse operations, repairs, warranty services and high-value products. A data file, sequence order and sample are required when each label has a different number or QR code.
| Item | Details |
|---|---|
| Product | VOID Tamper-Evident Label Printing |
| Common Uses | Electronic product seals, warranty labels, document seals, logistics security labels, tamper-evident packaging, product warranty stickers |
| Size / Shape | Quoted according to the seal position, application position and label use; strip seals, square warranty labels or custom shapes must be confirmed |
| VOID Material / Tamper-Evident Effect | The VOID tamper-evident material, residual lettering and tamper-evident effect must be confirmed according to the actual material and application surface |
| Application Surface | Results may vary on paper boxes, plastic surfaces, metal, electronic product casings, document envelopes or packaging boxes; the actual surface must be provided |
| Printed Content | The logo, warning text, serial numbers, QR codes, barcodes, batch data and dieline position must be confirmed |
| Variable Data | If each label has a different serial number, QR code or barcode, a data file, sequence order and sample must be provided |
| Factors Affecting Quotation | Size, quantity, material, tamper-evident effect, application surface, variable data, QR code / barcode, turnaround and artwork status |
If each label has a different number, please provide a clear data file, start and end numbers, sequence order and sample to avoid missing, duplicate or incorrectly ordered numbers.
These must be checked according to the label size, scanning distance, background contrast and print position; codes that are too small or lack contrast may not scan.
We recommend clearly stating "Tamper-Evident Seal", "Void if Removed" or "Warranty Seal" instead of only VOID Label, so users can understand its purpose.
Results may vary on paper boxes, plastic surfaces, metal, electronic product casings, document envelopes or packaging boxes. The actual application surface must be provided before quotation.
VOID tamper-evident labels mainly indicate whether something has been opened; they are not a complete anti-theft, anti-counterfeit or legal-grade security system.
Positions that are too curved, too narrow or easily subjected to force may affect adhesion and the tamper-evident effect. We recommend providing a photo and dimensions of the seal position.

From charity flag-day stickers to brand giveaways, stickers turn up everywhere — but picking the right one starts with the paper. This guide walks through the three everyday printing stickers: glossy coated art-paper, writable uncoated paper, and clear stickers with a white-ink underbase, plus the finishes each one can and can't take.
Peel a sticker and it leaves a sticky film behind? This guide explains why residue forms — glossy and cheap stickers on smooth glass or metal are the worst — then walks through six tested removal methods (hair dryer, eraser, rubbing alcohol, white vinegar, hand cream and WD-40), each matched to the surfaces it's safe on, plus a quick-reference table, safety notes and a no-residue sticker alternative.
A black bumper sticker is really a black-base advertising vinyl: the black backing hides the original surface colour so your graphic stays crisp. See where it works — walls, doors, fridges, metal panels, vehicles — where it doesn't, and how to pick gloss, matte or no lamination.
Making a die-cut sticker in Adobe Illustrator takes only a few minutes. This guide walks through setting up your file (A4, CMYK, 300 PPI, 3 mm bleed), checking artwork resolution, and building the cut line from either a raster image or vector art with a 3 mm offset — plus the sizing and spacing rules for a print-ready sticker sheet.
