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 KROENERT these trends lead to the handling of thinner substrates and to design coating machines for the application of functional layers. These layers can be protective layers as well as printing primers for transparent barriers with Aluminium oxide (so called AlOx layers) and functional barrier layers like PVdC. All this has KROENERT in focus.
