Tamper evident holograms in the form of stickers,
seals, labels are widely used holograms in various applications. Tamper
evident is a process that makes illegal access to any protected object
easily detected.
Tamper evident holograms are available in both reels and sheets to suit
any kind of needs-manual or mechanical. They are usually pressure
sensitive and are are available in colored, transparent or translucent
films.
The unique feature of this type of hologram is that
once affixed at the required place, any attempt to reuse these holograms
will lead to their destruction. This is because of the following
reasons:
- Some tamper evident holograms are very brittle and will
self-destruct when tampered with. This prevents swapping of stickers
or labels.
- Some tamper evident hologram sticker will leave behind a residue
or sticky substance when they are peeled away. Common messages like
"VOID", "OPENED" and checkerboard patterns
appear at the desired place.
- There are some tamper evident hologram sticker that changes color
if they are peeled away.
Tamper evident labels and seals examples include some
of the following:
- Asset labels and tags
- Computer security label seals
- Product warranty VOID tamper evident labels
- Bag seals
- Drug transport security seals
- Carton sealing printed security tape
- Chemical drum security seals
- Bag sealing tamper evidence tape
- Container security seals and tape
- Hologram Labels with Custom Imprint
- Hologram Labels without Custom Imprint
- Passports
- Identity Documents
- Bank Cheques, Drafts
- Driving License
Tamper evident holograms are of the following types:
- Full Transfer Tamper Evident Hologram:
In this type of hologram, the labels or seals once fixed at the
desired place, it is not possible to remove them. Any attempt to
remove the hologram or tamper with it results in only the top layer
of the film to be separated from the holographic image. What is left
is just a clear film, while the holographic image stays where the
hologram was originally affixed. This type of hologram is available
in various colors.
- Partial Transfer Tamper Evident Hologram:
In such type of hologram, any attempt to tamper with it or remove
it results in the holographic image breaking up. Partly the film is
removed or partly the substrate on which the hologram was affixed
breaks up. Any further attempts to still remove the hologram image
intact will result in completely destroying the hologram. Partial
transfer tamper evident holograms generally carry a checkerboard or
circular pattern.
- Transparent Holograms:
Transparent holograms as the name suggests are see through
holograms. They can be fixed over a number, text or a photograph to
make sure that they can be clearly visible. Any attempt to tamper
with the hologram will result in the complete or partial destruction
of the hologram.
- Translucent Holograms:
They are also see through holograms. While transparent holograms
merge with the substrate on which they are fixed , translucent
holograms stand out and are easily noticeable. They can be partial
transfer or full transfer.
