Environmentally friendly PE-replacement

Sustainable barrier coating solutions

Substances such as oil, fat or water have a strong influence on the quality of packaging. They attack the substrate, can damage the printing ink or impair the filling good. A barrier is therefore essential in many cases. Until now, PE layers have mainly been used as a barrier for packaging. Regarding sustainability, environmental and climate protection, however, it is important to avoid such PE composites. This is where alternative barrier solutions come into consideration.

Legally compliant varnishing (2/2)

UV coatings in food packaging printing

For the application of UV coatings in food packaging printing many requirements have to be considered. The analysis, if an overall packaging is suitable for the designated filling good, rests upon the responsibility of those who bring this packaging into circulation. Our White Paper explains the role of photoinitiators and why UV coatings can be used for the indirect food contact only.

LED-UV Technology

LED-UV coatings in the printing industry

LED-UV becomes increasingly important. This technology combines all advantages of traditional UV printing; however - compared to conventional lamps - without the emission of ozone or the use of mercury vapor lamps. This White Paper shows why we also need overprint varnishes in LED-UV printing and what needs to be taken into account when using them.

Digital Printing

Coatings in Digital Printing

As already experienced with regard to other printing methods, the varnishing of digitally printed folded boxes, labels and commercials gains more and more importance. Coatings do not only offer a protective function, but they also provide finishing effects, for example from gloss to matt. This White Paper shows which criteria to consider when choosing your coatings and it explains the challenges for coating manufacturers.

In-Mold Label Coatings: A Small Part of the Label with Great Effect

In-mold labeling (IML) has a small size and value compared with other decoration techniques, such as pressure sensitive, glue-applied labels or shrink sleeves, but it is quite an innovative market. There are not many players, as the production of IML labels is quite complex. All the technical details need to fit perfectly with each other so that the labels will work trouble-free at the injection molder or at the filling line. Substrate, inks and coatings must perfectly interact, or the results turn into a complete disaster.
