Adhesive coating is a surface treatment which involves applying a liquid coating (adhesive, lacquer, paint, oil, etc.) to a backing material (paper, fabric, plastic film, metal foil, etc.) to give it specific beneficial properties for a specific application.
The coating process is usually followed by drying and, if necessary, by cross-linking.

YungChi Adhesive Label Tape uses an engraved cylinder for its coating operations. The cylinder transfers the adhesive to the film which is then fed into a drying oven in which the solvents evaporate off.
Variables which affect the thickness of the liquid on the substrate:
Feed speed of the substrate
Viscosity of the liquid
Density of the liquid
Angle between the substrate and the surface of the bath
Surface tension
