Warranty seals. Special security stickers for product servicing.
Sometimes, customers, relying on their abilities, try to interfere with products or repair them themselves.
In such a situation, manufacturers should use popular, durable sticker warranty seals to protect the product and discourage customers from inappropriate servicing actions.
What are warranty seals?
These are small security stickers shaped and sized to fit service access points. They may also contain information about service deadlines, so they often display only the logo or company branding.
The company usually uses them as important product protection during the warranty period. This is when the manufacturer is responsible for the product’s reliability.
They are weather-resistant and adhere permanently to any surface. A popular type is void labels (hologram).

How do security stickers differ from regular ones?
The main difference between warranty stickers and traditional labels is that we use several types of tamper-evident film in their production.
This type of film is as brittle as plastic and has a strong adhesive. Therefore, once applied to a product, any attempt to remove the seal results in the sticker breaking into pieces. As a result, it is not suitable for reuse. This differs from labels made of standard film material, which we usually use in our sticker printing business.
These are not yet void versions (holograms), which delaminate across their entire surface when attempting to be removed. They leave difficult-to-remove markings on the product. A permanent void marking and adhesive residue appear—the glue is transferred onto the protected surface.
The warranty label made of brittle film crumbles when attempting to remove it and can only be used once to secure the product.
What is the minimum production budget? You can print tamper-evident stickers with us starting from 500 PLN net.

How do self-adhesive film labels protect products?
The correct use of seals involves applying them in key areas for disassembling or servicing the product. Typically, these are the junctions of the casing components or areas where access to the screws that secure the product is available. This prevents the casing from being opened without compromising the product. Unauthorized individuals will not have access.
The warranty card should also include information about securing the product with tamper-evident stickers. This way, customers are fully aware of the usage and servicing guidelines.


If the customer violates the label, they will lose the right to warranty repairs. Therefore, the manufacturer is assured that their rights are properly protected.
The crumpled lead foil is matte and perfect for writing on, making it ideal for marking the product’s current service status.
Warranty seal stickers are highly effective in servicing machinery and equipment where the time and service quality is crucial. Therefore, they are essential labels for every service company. They allow for confidential access and exclusive servicing.
They are perfectly suited for marking electronic equipment, electrical devices, and frequently serviced goods. Additionally, check out our service stickers, which complement warranty seals.
A special film with a very strong adhesive prevents the label from being removed without damage. It is also impossible to reapply it, and any attempt will result in damage.

Specialist printer of security seals
As part of our production, we can supply tamper-evident labels. The shape, colour, and size of these labels can be customised. They can be round, square, or rectangular.
We use full-colour printing techniques in production so that the sticker protects the product from opening and visually complements it well.
This special sticker can simultaneously serve as packing tape and a security seal.
Ready-made black security labels can be purchased from any online store. However, if you want printed sheets of void labels or fragile film with your company logo or custom design, it’s worth commissioning the printing to specialists. You can also request a print-ready design in roll format.
In addition to choosing your format, you can incorporate personalisation elements (e.g., numbering). By using CMYK or Pantone printing, you can accurately represent your brand’s image.
We recommend the production of special stickers to all manufacturers and invite you to contact us. If you want to test our solutions’ durability, film, and surface, please contact us for free samples. This will allow you to check their removal properties.
