Hologram seals or security seals are a widely demanded quick and economical way to add security to existing cards and packaged goods. Hologram seals are also used to detect tampering while a shipping carton is in transit or storage. The seals are carefully crafted and produced to prevent counterfeiting. Unlike peel-off seals, the hologram seals leave a dot or checkerboard pattern on the card or packet if they are removed, indicating that the card has been tampered with. Any attempt to remove these seals destroy the seal and nullify the guarantee of authenticity.


The hologram seals are available in various shapes and sizes, including custom made seals with company's logo and images. Additional levels of security can be added with the images that change color and appearance when viewed from different angles.

Types of Hologram Seals

There are usually two types of holographic seals available based on the basic substrate used. They are as follows:

• Polyester-based Seals : The self-adhesive polyester based hologram seal is ideal for general use. This kind of seal is used where high security is not a main priority. The main uses for polyester based hologram seals include promotional labeling uses and seals for packages, like cosmetics and CDs. The seal is made from a polyester film, easily applicable either by hand or machine. Serial numbering is also available on seals for track and trace purposes.
  
  
• Paper Based Seals : The paper-based seal can be used as an information label, while at the same time providing the authenticity supplied by the holographic strip. The paper hologram seal is ideal for cases where additional labels are needed, like in food and beverage packing where nutritional information and ingredients be provided. The paper seal will work as a two-in-one label. Any attempt to remove the seal will result in the label tearing.

Tamper Evident Feature of Hologram/Security Seals
