Seal sticker

Seal stickers: making first opening visible – with paper or VOID film

Whether for shipping packaging, product samples, or sensitive goods, seal stickers make integrity and first opening immediately visible. As soon as someone tries to remove the seal, a clear indication of tampering appears, depending on the material either through destructible paper or through a VOID effect on film. Individually printed seal stickers from Labelprint24 can be freely configured.

Seal stickers, also known as seal labels or closure labels, are typically applied across an opening. If the label is intact, the packaging has not been opened. This makes them useful for product protection, quality assurance, and building trust with end customers.

Typical applications for seal stickers

Seal stickers are used wherever tampering, contamination, or fraud should be visibly prevented, for example:

Especially for products with a higher value or compliance requirements, seal stickers are a simple and effective way to clearly communicate that a product is “unopened”.

Three suitable materials for your seal stickers

Three security materials are relevant for this product page: two film options (VOID PET) and one paper option (destructible paper). All three can be individually printed and configured in your desired size.

1) VOID PET film – white/transparent (extra-permanent)

This film is the robust solution when your seal needs to withstand demanding conditions. When someone attempts to remove it, the VOID effect is activated and makes tampering permanently visible. It is suitable for indoor and outdoor applications, dry and wet areas, and remains reliable even during temperature fluctuations.

Ideal for: shipping, storage, device labelling, and product sealing with increased environmental requirements.

2) VOID PET film with hologram (extra-permanent)

If tamper protection and counterfeit protection are both required, the hologram version is the premium option. Here too, the VOID mechanism takes effect when the seal is removed. In addition, the “Genuine” lettering in the hologram design changes, making any tampering even more noticeable.

Ideal for: high-value products, authenticity and warranty seals, retail and reseller structures.

3) Security label made of paper – opaque, tamper-proof and destructible

Destructible paper is the right choice if you need a seal that cannot be removed cleanly. Thanks to its opacity, the material also appears non-transparent and high-quality, especially on neutral or varying surfaces.

Ideal for: indoor applications in dry areas, folding boxes, sample sets, and first-opening seals in retail.

Printing, size and configuration: as flexible as your application

At Labelprint24, you can configure seal stickers in a custom size to match your packaging, from discreet closure seals to eye-catching security labels. Depending on the order quantity, printing is carried out using digital or flexographic printing, ensuring that quality and price are aligned with the required volume.

Variable content such as numbers, codes or barcodes can also be integrated, for example for batches, serial numbers, returns or authentication processes.

Fast production, delivery and expert advice

Express production from 2 days, including free delivery, is also available for these labels. If you are unsure which material is best suited to your surface, temperature conditions or handling requirements, personal expert advice is also available.
