A major problem for brand owners is "counterfeit products" and "fake warranty claims," which cause immense damage. The question is, which protective measure should we choose? Security stickers or warranty voids ?
This article C2S Printing will take you on an in-depth look at both types of security stickers so you can choose the right one for your needs and get the best value for your budget.
1. What is a warranty void sticker? How many types are there?
Its primary function is "Do not remove," used for warranty checks. If the sticker is damaged, the warranty is immediately void. There are three main types commonly used:
1.1 Void (Residue Void)
This is the most popular standard type. When peeled off, it leaves a "VOID" message or a checkered pattern on the product, and the sticker is damaged beyond repair.
- Suitable for: Packaging boxes, product bottle caps, spare parts boxes.
- Highlights: Low price, obvious signs of tampering.
1.2 Void (Non-Residue Void)
When peeled off, the sticker will show "OPEN VOID" (damaged sticker itself), but it will not leave any sticky residue on the product.
- Suitable for: Premium products that must not be soiled, such as camera lenses, connection ports, and security doors.
- Key feature: Preserves the product's aesthetic appeal while providing 100% protection against tampering.
1.3 Eggshell Stickers (Destructible / Eggshell)
The sticker material is very fragile, like an "eggshell." When you try to peel it off , it immediately shatters into small pieces; it cannot be peeled off as a sheet.
- Suitable for: Screw seals, IT products, computer components.
- Key feature: Provides the best protection against product swapping because it's impossible to open and reseal the contents.
2. How are anti-counterfeit stickers superior?
If your goal isn't just about insurance, but about "authentication" to build customer trust, you need these advanced techniques:
2.1 Holograms (2D/3D)
Laser foil with overlapping dimensions creates a moving image when viewed from different angles. The advantages include being "impartially photocopied" and highly difficult to counterfeit, enhancing the product's image and making it appear more expensive and trustworthy.
2.2 Invisible Ink
C2S Printing proprietary technique C2S Printing that is invisible to the naked eye but glows when exposed to blacklight (UV). It is commonly used to conceal secret codes or brand logos to verify authenticity.
2.3 Running Number & QR Code
The variable data printing system, such as printing a unique serial number on each item or a QR code that, when scanned, links to a product verification page, allows for tracking of individual items.
