Growing environmental awareness prompts the chemical industry to develop new products such as solvent-free laminating adhesives and solvent-free silicones for label production.  KROENERT works closely with the chemical industry. The company’s large in-house research centre is crucial to development. New machine concepts and coating methods (5-roller technology) are developed.

1956

The RECO series is born. RECO stands for REverse COating.
A well-known trademark, the RECO remains to this day the most widely built and most versatile machine type in the KROENERT product range.

1936

Glue laminating line for paper and thin aluminium foil built for the first time in its distinctive shape with large drying cylinders. Later this family of machines was named GROTHA – after a Dutch customer in the wholesale paper trade.

1922

The first paraffinizing and laminating machine called the “KÖNIG” also sees the light of day in 1922 –
it is the start of a long and successful development in the construction of wax coating and laminating machines.

1903

Shortly after being established, KROENERT moves to Schützenstrasse in 1905 – where we are still based to this day.
