• 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.

About us

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
