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
