Abstract

Coatings for paper are categorized into two groups: pigmented or functional. Functional coatings provide functionality in addition to the normal coating properties. Functional coatings can be used for friction control, release properties, abrasion resistance, and barrier properties. A coating that is designed to control barrier properties can be categorized into a sub-group of functional coatings called barrier coatings.

Barrier coatings can retard or eliminate the flow of fluids thru a coated substrate. The barrier can be effective in repelling or resisting the transmission rate of numerous fluids including moisture, oil, oxygen, grease, and glycerol. Barrier coatings have many useful applications due to the need of barrier coatings for a wide range of fluids. Barrier coatings have been used in packaging for pharmaceuticals, cosmetics, pet food, liquids, and food. A potential useful functional coating is one that will act as a barrier for water and glycerol while maintaining fold properties of the substrate. This study seeks to examine the barrier properties of various functional coatings applied to various commercial anti-wicking base paper. The influence of barrier coating layer on the dead-fold properties will also be studied.
