Case study

Industry 4.0 and the chocolate factory

Industry: Food

Application: Coding and marking of packaging

Material: Cardboard and plastics


Chocolat Frey AG is the undisputed leader in the Swiss chocolate mar-ket (market share of 33.2 % in Swiss retail. Source: Nielsen). The choco-late manufacturer began producing chocolate bars and chocolate pow-der in 1887.

Today, the company offers a wide range of taste sensations including chocolate bars, pralines, snacks and chewing gum – under the umbrella of the Swiss Migros trading group.


A marking system with a high num-ber of interfaces was required to mark cardboard and plastic packa-ging with a best-before date and a batch number, also as an overhead application.

At the same time, aspects for the digitalization of industrial production (industry 4.0) had to be considered in order to pave the way for the individualized mass production of chocolate products.


Chocolat Frey AG opted for the LEIBINGER JET3up, which meets all its requirements – also thanks to the interfaces available as standard. The unique Sealtronic technology from LEIBINGER was also very con-vincing. The fully automatic nozzle sealing system hermetically seals the entire ink circuit during production breaks. This prevents the ink from drying out. The printer is therefore ready for use at any time – without cleaning.
