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.
