Printability
Let the ink flow!
Having good ink can make all the difference between an impressive document and one that goes unnoticed.
The addition of hydrophilic colloidal silica to a resin based coating for OPP film can make the coating more receptive to water (hydrophilic) - enhancing the adhesion of waterborne inks. Silica can also be used in print varnishes to improve mechanical properties.
Another approach is to use cationic colloidal silica in ink-jet coatings. When allowed to dry, the silica agglomerates with a small amount of binder to create a porous coating with excellent dye fixing properties.
