New printing inks with barrier performance for packaging applications

Barrier properties of packaging materials against moisture and oxygen penetration are of high relevance. Enhanced protection of existing materials against weather conditions can be achieved by application of printed coatings.
To improve barrier performance of packaging materials, researchers at the Fraunhofer Institute in Germany developed and investigated new inks for obtaining printed coatings with a layered structure.
The researchers found that coatings based on the developed printing inks demonstrated significantly decreased water vapour permeability compared to traditional polymer inks. An article about the research is published in Progress in Organic Coatings.
