The boxes are designed with up to 14 UV printing inks using underprinting and overprinting with various finishing including hot-foil printing in glossy gold or embossing.
Multiple trials with different materials
Klaus Volgmann, European key account manager, Confectionery, rlc, told ConfectioneryNews, iriodin pearl luster pigments contain thin platelets of the natural material mica, coated in a wafer-thin layer of metal oxide.
This creates semi-transparent pigments which give a coating the soft, deep luster that is characteristic of pearls and mother-of-pearl.
"We worked in close cooperation with Nestlé for about six months. We conducted multiple trials with different materials to come up with the best packaging," he said.
“The surface has a slightly rough feel and attracts attention with a subtle sparkle – thanks to the use of iriodin pigment. This does not affect the color brilliance and diversity in areas with photos or colored surfaces.”
The folding box design was created by artist Marianne Dubuis using a traditional "découpage" cut-out technique.
She created hand-made silhouettes of grazing dairy cows and a view of Maison Cailler company headquarters.
Relief and blind embossing
rlc then transferred these images to the packaging surface through relief and blind embossing. The packaging is embellished with the company logo in hot-foil embossed gold.
Nestlé sells the chocolate brand through online retailer Amazon in the US, UK, Germany and China and international airports in Geneva, Zurich, Dubai and Singapore and the Maison Cailler flagship store in Broc, Switzerland.
rlc produces boxes for four "Art du Brut" Cailler chocolate bars with roasted nuts and dried fruit and four L'Ecorce, thin chocolate tablets in various flavors.
The Cailler brand, acquired by Nestlé in 1929, has been sold exclusively on the Swiss market since 1819. Nestlé says it is the oldest chocolate brand in Switzerland that still exists today
The Cailler brand uses UTZ Certified cocoa from the Nestlé’s Cocoa Plan. The UTZ logo and Nestlé Cocoa Plan are communicated back of pack. The cocoa butter is derived from a blend of Ivorian, Ghanaian and Ecuadorian cocoa beans.
