Barrier Coating for Sustainable Packaging
What Is a Barrier Coating for Papers?
In an effort to reduce plastics in packaging, barrier coatings 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 better protection. Barrier coatings can be used on food packaging paper or non-food packaging paper.
Food, pharmaceutical products, cosmetics, and liquids can be packaged with barrier coated material in order to control the required quality, safety, and shelf life, and is an Environment friendly packaging option. These products must be 100% re-pulpable and re-cyclable for packaging materials to become sustainable.
Barrier coatings can also provide heat sealability to form packaging material in order to effectively replace PE coating.
