This film has excellent handling properties and is used for printing & lamination in Flexible Packaging Industries. In this chemically coated film is also available on single side to improve adhesion for printing or coating. Metallised Polyester Film in Silver (Unlacquered) & Gold (Lacquered) is also available for Packaging Industries. As it prevents the food articles for proper aroma and resists moisture as it has good moisture barrier (MVTR/OTR) properties. It is also used for easthetics application. |
