Testing of Curtain Coated Material

Sep 4, 2019

Curtain coating results in an even surface covering of board or paper, often providing functionality e.g. barrier properties. The materials mostly need to be printable, convertible and preferably recyclable.

In addition to testing strength and surface, we provide multiple standard and in-house barrier methods for evaluating resistance to grease, moisture and water vapor. By utilizing our staining methods under a microscope, we are able to analyze coverage and evenness of the barrier.

The surface energy of the material is an important indicator of printability and glueability of the coated material. Surface energy measurement is frequently used in trouble shooting problems during printing, converting and end use.

Effective early September, we can offer surface tension and surface energy measuring with a completely updated device.

Fiber based materials are most often required to be recyclable. Different testing methods are available for predicting recyclability as well as re-usability of the recycled fiber material in paper or board applications.
