Security labels are largely used for sealing of electronics, measuring devices, for security against falsification of goods of various brands (foodstuffs, alcohol, cigarettes, jewellery, clothing), as a security sealings for various types of documents (particularly useful for a notary), and everywhere where the security of a product needs to be ensured or where the origin, quality, or other important characteristic of the good needs to be secured.
The usage is fairly wide. There are basically three different special materials available, which differ by price as well as suitability of use for a particular job. A fourth option is the use of standard material with security die-cutting.
