The Root of the Problem

Solution: Low surface tension can be corrected with in-line or pre-treated substrates, and will make the substrate better able to hold inks and adhesives.

Low coating weights can be fixed at the coating stations or by ensuring that the correct amount of adhesive is specified for a given application. This is essential, since coating weights control the rate of application, and in turn "the application rate will effect the flexibility, adhesion, COF (coefficient of friction), and rub resistance of a coating," said Matthiesen.
