What Is a Barrier Coating for Papers?
In an effort to reduce plastics in packaging,Ā barrier coatingsĀ are applied to paper, paperboard, or corrugated board to restrict the flow of oil, grease, water, oxygen, or moisture through a variety of materials in order to accomplish betterĀ protection. Barrier coatings can be used onĀ food packagingĀ paper orĀ non-food packagingĀ paper.
Food, pharmaceutical products, cosmetics, and liquids can be packaged withĀ barrier coated materialĀ in order to control the required quality, safety, and shelf life, and is anĀ Environment friendly packagingĀ option. These products must be 100% re-pulpable and re-cyclable for packaging materials to become sustainable.
