Pearlescent coatings (pearlized varnishes) contain microscopic platelets of natural or synthetic mica crystals coated with titanium dioxide.

### Visual Phenomenon:

Rather than reflecting light like a mirror (such as foil), pearlescent mica crystals refract and diffuse light, creating a soft, iridescent, satin shimmer reminiscent of real pearls or sea shells.

Colors shift subtly depending on the viewing angle.

### Ideal Packaging Uses:

Anti-aging skincare and prestige beauty cartons

Wedding favours and bridal gift packaging

Luxury champagne and sparkling wine gift cartons

Artisanal candles and spa bath products.
