Activation prior to labelling, printing or metallisation

Achieving good adhesion of coatings on plastics is challenging because these materials are often hydrophobic and have low surface energy. Surface preparation is therefore necessary to improve the adhesion of adhesives, paints or coatings.
Common methods include adhesion primers, which can sometimes be harmful to the environment.
Plasma is a more environmentally friendly alternative.
In addition to plastics, it is possible to improve the surface of many materials using PECVD treatment.
