Metalized poly film, also known as metallized polyester film, is a type of packaging material that combines the properties of polyester film with a thin layer of metal, typically aluminum, deposited on one side. The metal coating enhances the film's barrier properties, making it an effective option for applications requiring moisture and gas resistance. Metalized poly film is commonly used in food packaging, flexible electronics, insulation, and decorative applications.
