Flexography in Package Printing

Flexo benefits on inking edge
The latest developments of polyurethane (PUR) resins have opened up new applications. The successful increase of flexography printing of, for example laminates, is highly correlated to the almost unlimited possibilities of the PUR synthesis. Modern polyurethane resins are synthesized through the complex combination of various intermediates by multi-step reactions. Thus high-molecular, film-forming resins are formed exhibiting excellent adhesion properties, high solubility in alcohol, lowest solvent retention, high blocking and sterilization resistance. Properties of polyurethane resins can be varied in multiple ways by selecting specific intermediates. Tailor-made PUR resins can be manufactured and their characteristics can be adjusted exactly to the respective requirements.
