LumaChrome Holographic Gives Two-Factor Authentication

Nanotech Security Corporation, now owned by Meta Materials Inc, is perhaps best known for designing, originating, recombining, and mass-producing nanotechnology-based films for securing documents of value against counterfeiting and tampering. But the Canada-based firm also offers a range of labelling solutions for advanced brand protection, to which it has now added a holographic version.

As you might expect from the name, LumaChrome™ Holographic combines Nanotech’s colour-shifting LumaChrome film with an embossed holographic security pattern to give two-factor authentication. Customers can choose the colour-shift options for LumaChrome from four different possibilities:

The colour transition and holographic image-switch effects are immediately visible when the viewing angle is changed. As a combination, says Nanotech, these unique effects are simple to recognise, difficult to replicate, and incredibly effective from a considerable distance, multiple angles, and variable lighting conditions.

The LumaChrome Holographic material is available in a variety of label constructions.

The tamper-evident format is comprised of, from the uppermost layer down:

• Layer 4 – customised brand elements, serialisation.

• Layer 3 – holographic security pattern.

• Layer 2 – LumaChrome colour-shifting film.

• Layer 1 – tamper-evident layer.

To support the high-volume production of LumaChrome Holographic, Nanotech utilises two large roll-to-roll optical thin film deposition coaters in its high-security production facility. With the ability to operate up to four separate deposition zones simultaneously, Nanotech can produce highly customisable films, very cost effectively. Operating each coater at peak output, it has the capacity to achieve more than 250,000m2 of film a month.

Film and labels are available in multiple formats and can be used for brand protection, anti-counterfeiting, and smart packaging in industries such as pharmaceuticals, cannabis, retail membership and gift cards, electronics, and imaging supplies.
