Tamper-evident security stickers can generally be divided into three types according to the tamper effect after removal: full-transfer, partial-transfer, and non-transfer.
After full-transfer or partial-transfer stickers are removed, VOID OPEN, VOID text, or tamper marks transfer onto the applied surface, while the label itself also shows a tamper-damaged effect. Even if the removed label is not kept, the remaining mark on the applied surface can serve as evidence that the item has been opened, removed, or tampered with.
Non-transfer stickers mainly show tamper damage on the label itself and do not leave VOID text or tamper marks on the applied surface. They are commonly used in applications where residue or visible marks on the surface should be avoided, such as no-photo stickers, mobile phone camera control stickers, product seals, warranty labels, equipment seals, and tamper-evident management.
This product is a non-transfer tamper-evident security sticker. When the sticker is removed, VOID OPEN, VOID text, or tamper marks appear on the label itself instead of transferring onto the applied surface. This design helps management personnel identify whether the sticker has been removed, while reducing the risk of visible text or tamper marks remaining on the applied surface.
Non-transfer tamper-evident security stickers are suitable for applications that require both tamper indication and surface protection. For mobile phone camera lenses, display items, equipment housings, rental items, or other surfaces where visible residue or marks should be avoided, the adhesive type and product option can be evaluated according to the actual material and application conditions.
Please note that although non-transfer stickers do not transfer VOID text or tamper marks onto the applied surface, different materials, coatings, application duration, and environmental conditions may still affect the removal result. If the sticker will be applied to special coatings, plastic housings, lens protectors, or high-value surfaces, actual sample testing is recommended before formal use.
