The world's first functional film using color-converted
photonic crystals
High-humidity sensitive film can be easily
and quickly checked for
authenticity without additional tools, and
various colors can be
realized without dyes and only by adjusting
the coating
thickness.
Non-replicable label
Without the use of dyes, solution coating
and printing technology of polymer materials blocks the source of the
possibility of duplication
user convenience
Authenticity can be verified with just a
breath and a finger touch without any authentication tool
ㆍConsumer directly confirms authenticity
through high-humidity color conversion
great design
Various colors can be realized from UV
range to IR range
ㆍVarious colors and designs can be produced
depending on the viewing angle
High humidity activated film can be applied
to not only security market but also design market, daily supplies, money
market
Luxury goods Luxury goods have to be
protected from counterfeit for value of brand
Medication
Because, Medicine is connected to our
health directly, Medicine must be checked before dose whether that one is fake
or not
Cigarette Prohibited ingredient can be
included in counterfeit cigarette
Electronic products Guaranteed electronics
by official High humidity activated film can get the AS without any assurance or receipt
If the user blow the breath to High
humidity activated film, official Mark and color are being beautifully changed.
It can be easily used as security solution to distinguish official product or
counterfeit for anyone
When the film is exposed to high humidity,
photonic crystal structure is being changed. And this changed structure causes
different wavelength of reflective light, so the film looks different color on
human's eye. This engineering structure has not only security function
but aesthetic effect also
