KODAK ESTAR Polyester (PET) films offer very high clarity, optical-grade surface quality for use in a variety of industrial applications. These films can be processed uncoated or with coatings on one or both sides of the material — up to three coatings per side. Coating options can include:
- Adhesion promoting primers
- Anti-static coatings
- Gels
- Adhesion coatings for aqueous or solvent based inks.
- Features
- Optical-grade surface quality — products are manufactured with minimal surface contact, then scanned to meet the stringent requirements for optical applications.
- Greater than 90% transmittance with less than 1% haze.
- Available in an array of widths and thicknesses.
- Throughout the stretching process, films are transported on a cushion of air without roller contact to virtually eliminate micro scratches that can compromise quality.
- Kodak’s Six Sigma Black Belt quality strategy includes statistical modeling and design, rigorous change management, and unsurpassed manufacturing process control.
- Films are available bare or can be coated on one or both sides with a variety of adhesives, gels, inks or anti-stats.
- Available in thicknesses as low as 2.5 mil (63.5 µm) and as thick as 7.5 mil (188 µm) up to a maximum width of 1384 mm (54.5 inches).
Applications & Uses

Roll Intergrity
- The edge of the roll will be free of nicks, cuts or visible telescoping greater than ± 6.3 mm (0.25 inches).
- The roll will not contain gage bands which will visibly distort the film surface.
- There are no splices or cutouts in the roll.
Product Quality
- Kodak inspects material during the manufacturing process using in-line scanners to detect, correct, and deliver material that meets or exceeds specifications.
- Kodak quality technicians consistently evaluate sample product quality using internal and external standards to confirm quality standards are met.
