Film Casting - an overview | ScienceDirect Topics

Solution film casting dates back to the nineteenth century [2] and is the oldest film formation technology used to make the early photographic films. To cast a film, a solution ("dope") of a polymer in a solvent is made and applied to a moving metal belt with a smooth surface [3].The wet film levels on the belt before entering the drying zone, where the solvent is completely removed.
