Polyester film is a high-performance, crystal clear thermoplastic made from Polyethylene Terephthalate (PET) resin.
In comparison with other common plastic films, PET film has high tensile strength, excellent dimensional stability, low moisture absorption, and good retention of physical properties over a fairly wide temperature range.
It also has superior UV resistance and excellent electrical properties, and good optical clarity. Because of its higher price relative to PVC, PE, and PP film, it is generally considered a specialty film.
