Polyester Film

Polyethylene terephthalate or polyester (PET) is a versatile plastic widely used in many applications. PET exhibits good chemical resistance and is a tough, durable plastic as compared with other commodity resins in a similar performance and price range.


The dimensional stability of polyester film or PET film has found application in laminates, membrane circuitry, electronic insulation, carrier films, face shields and any number of graphic arts applications.


Most readily produced in gauges from 48 gauge (1/2 millimeter) to .014, PET film is available as print treated one or two sides for easy print-ability, slip treated for ease of handling, and in options such as super clear, clear, hazy and white depending on your particular needs.


Mylar® offers unique design capabilities to the electrical industry due to the excellent balance of its electrical properties with its chemical, thermal, and physical properties.


Polyester or polyethylene terephthalate (PET) is a high-performance, crystal clear thermoplastic made from ethylene glycol and dimethyl terephthalate (DMT). In comparison with other common plastic films, PET film has higher 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, excellent electrical properties, good optical clarity, high gloss, and good gas barrier but only moderate moisture barrier properties. It is the ideal film for quality printing and lamination and a good choice for a high performance plastic films and sheets. It has a relative high melting point, which makes it suitable for applications that require sterilization at high temperatures
