Cosmo Films' wide range of Barrier films are used to protect food and other perishable items from oxygen, moisture, and other environmental factors that can cause spoilage. Metalized barrier films are made by coating a layer of metal, typically aluminum, onto a polymer film. This creates a barrier that is highly effective at preventing oxygen and moisture from passing through. Our world class metalized barrier films are used in a variety of applications, including food packaging, where they help to extend the shelf life of products by preventing oxygen from entering the package and spoiling the contents.
