• JSC “Holtida” specializes in development of advanced optical security
means.
• JSC “Holtida” was established in 2014 as spin-off company, which
extends over 20 years of experience developed by a team of scientists
in the field.
• Establishment of the company is partly funded
- by the Agency for Science, Innovation and Technology
- Innovative business promotion programme (INOVEKS)
- and supported by Kaunas University of Technology, enabling the use
of infrastructure of “SANTAKA” Valley, Science and Technology Center
and the Technology Business Incubator.

Needs
The extent of
counterfeiting
The extent of counterfeiting
is estimated to be from 300
to 600 billion dollars per
year.
SecurityAdvanced holographic and
kinematic security effects
are used to ensure the
authenticity of labels.
Applications JSC “Holtida” produces the
original holographic labels
for security, product
authentication, and
protection against
counterfeiting
