Polyester Film
Strong, transparent, dimensionally stable plastic films with outstanding chemical resistance
About Polyester Film
Biaxially oriented polyester films have outstanding mechanical strength, dimensional stability, transparency and chemical resistance. They are available in many different grades and they are used for a wide range of applications. Polyester film is sold in rolls or cases of 100 individual sheets.
Length, width, thickness, and diameter tolerances vary by size, manufacturer, brand, and grade. Custom sizes are available upon request.
Polyester Film Properties and Material Options
General purpose PET polyester films– including Skyrol® SR50, Skyrol® SG00, Mylar® A, and Melinex® 461, offer excellent mechanical properties, dielectric strength, and dimensional stability, along with low water absorption and good resistance to most chemicals. These polyester films are often used for industrial laminates, electrical insulation, electric motors, and cable insulation.
Print treated polyester films– including Skyrol® SH22, Skyrol® SH82, Skyrol® SW84G, and Melinex® 561, are print-grade PET polyester films with enhanced adhesion to inks, adhesives, and coatings. They are used for printing and solvent-based coating applications and are often specified for printed labels, masking applications, engineering drawings, face shields, and other industrial applications.
Slip treated polyester film– Skyrol® SH72S is an optically clear, two side slip treated polyester film with high clarity and gloss, good dimensional stability, and excellent handling characteristics. SH72S is used for flexible packaging, face shields, spacers, gaskets, and carrier film applications.
Hard coated polyester films– including Flexiber UV01 and Flexiber MP01APM have UV-cured hard surface coatings that give them excellent scratch resistance. These materials have a smooth surface on one side and an anti-glare surface on the reverse side. These films are used in automotive applications, membrane switch overlays, appliances, nameplates, and touchscreens.
Tech Tip– Although biaxially oriented polyester films have excellent resistance to many industrial chemicals, they tend to become brittle when exposed to hot water and steam.
