Polyester Film Properties and Material Options
General purpose polyester films– including Skyrol® SR50, SR53, and SG00 and Garfilm EM6 have excellent mechanical properties, dielectric strength, and dimensional stability, as well as low water absorption, and good resistance to most chemicals. These general purpose films are often used for industrial laminates and electric motor and cable insulation.
Print treated polyester films– including Skyrol® SH22, SH82, V5400, and SW84G are print-grade polyester films that have enhanced adhesion to inks and adhesives. They are used for printing and solvent-based coating applications. These films are often specified for printed labels, masking applications, engineering drawings, and face shields.
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 applicaitons.
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.
Heat stabilized polyester film– Skyrol® AH68L is an optically clear, glossy film with an adhesion promoting pretreatment on both sides (one side acrylic/one side urethane). It provides very low heat-shrinkage due to the heat stabilizing process. This material is typically used for printed circuits and electronics. Skyrol® AH68L supercedes Skyrol® AH82L.
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.
