Metalized films are a game-changer in the flexible packaging world. They consist of a plastic film that has been coated with a thin layer of metal, usually aluminum, to boost its barrier properties. These films are a cost-effective and environmentally-friendly alternative to foil in laminates, providing a comparable level of barrier performance. We use metalized film for packaging of various products, such as snacks and confectionery, to prevent moisture, light, and oxygen from compromising product freshness.
