About us

KROENERT are the coating machinery experts. The development and construction of coating and laminating machines for the production of flexible packaging material as well as the installation and service are provided by the production site in Hamburg, Germany. Since 1903, KROENERT develops and builds innovative custom-made machineries. The name of the company stands for quality and reliability, the best in class efficiency, persistent construction and short maintenance times within production. Very important are economy and ecology – wherever possible – resource reducing concepts are implemented.

KROENERT offers training and technological support, not only at the in house Technology Center, but also at our customers.

Complete coating and laminating machines also as stand-alone units, equipped with:

  • Un- and rewinder
  • oating station with 60 different methods
  • rying technology as convection, IR and UV
  • aminating, humidifiers, cooling sections and condensation units, etc.

RECO 800 A for the production of flexible packaging material

RECO 800 A, coating and laminating machine.
Tailor-made to produce flexible packaging material, web width 800 to 1.650 mm, production speed up to 1.000 m/min. This line is used for solventfree and solventbased lamination as well as lacquering and cold seal coating of paper, film and foils. An option is glue lamination of paper with aluminium foil.
Key components are the coating systems to ensure quick change of the coating method and winders for a flying reel change at production speed.

Trends and expectations in packaging films and functional polymer films

Barrier layers are applied to packaging films, to protect the packed product against environmental influences. Besides that, the barrier layer also works as a sealing layer to combine different materials with each other, such as a food box with the top cover. Environmental influences can be moisture and oxygen as well as viruses, bacteria and infectious substances. „Smart-packaging” materials, meaning resource efficient products which are focusing on material efficient use as well as materials with a better CO2 foot print gain in importance mainly in China and India. Wasting of food is an important target to reduce lack of food worldwide.

For coating machines, such as produced from side of the company KROENERT as supplier of custom made machines, on one side these trends lead to the handling of more and more thinner substrates. On the other side, coating machines have to be designed for the application of functional layers. These layers can be, for instance, protective layers as well as printing primers for transparent barriers with Aluminium oxide (so called AlOx layers) and functional barrier layers like PVdC. All these topics has KROENERT in focus for the development of machines and new processes.

Even for barrier layers PVdC (Polyvinylidene chloride) is currently dominating the market are alternative products developed. Transparent barrier layers with high barrier properties are gaining importance. Aluminium oxide (AlOx) clear barrier coating has become one of the favoured choices for flexible packaging. They are more and more common in use. However, the transparent ceramic barrier layers need to be protected as well as coated with a primer layer for printing applications. The development of new solutions is focused at KROENERT and will be discussed during the Chinaplast in Shanghai beside new high-end developments for polymer film applications.
