Plastic films for food packaging are often coated with one or more oxygen and/or water vapor barrier layers. It depends on the food packaged. Apart from the well-known films such as aluminum vacuum metallised or aluminum foil laminates, the packages can be made of films coated with transparent barrier layers. The main advantage of films…
