Plain Polyester film- 10 & 12 Micron I Metallised Polyester film (Silver & Gold) - 12 Micron

Polyester film is the perfect choice for Packing Snack Foods, Confectionery, Cosmetics, Pesticides, Pharmaceutical as well as Commodities like Tea, Coffee, Oil, Detergents, etc., due to its excellent external properties like Gloss, Printability, Thermal Stability, Tensile Strength as well as its Ameanability to Heat sealing & pouching. It is also used for the Lidding applications on PET' trays & bottles. The film is also available with chemical coating on one side to give improved ink adhesion required for high quality printing & lamination.

Polyester film Co-extruded, one side Heatsealable having wide heat seal range of 120° C- 200 ° C provides excellent protection to Loss of Freshness, Flavour & Aroma. Even it is safe for use in food contact applications. Therefore, products like Spices, Tea, Detergents, Soaps have found superior packaging medium. It provides protection from solvent contamination better than other heatsealable materials like OPP & LDPE since it has high barrier properties to solvents commonly used for printing & lamination process.

Polyester film co-extruded with soft layer of a special polymer gives it excellent Twist Retention properties. Metallised Twist Wrap grade film becomes the best choice for wrapping chocolates & confectioneries giving them tempting look at first sight.

When Metallised, it offers a far superior Packaging medium for a variety of sensitive products due to its enhanced Barrier proprieties. Lacquering protects metal by preventing the Oxidation of metal. Thus, Metallised and/or Lacquered film (in colours like silver / gold / copper) not only ensures prolonged Shelf life of the contents packed in but also imparts an eye catching attractive look.

It can also be laminated to different substrates like LDPE, HDPE, Aluminum foil, BOPP & Polyester to give it strength & Outstanding looks.
