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.

Because of its higher price relative to PVC, PE, and PP film, it is generally considered a specialty film.

PET can be metallized which results in improved gas barrier properties for demanding applications where long product shelf life is important. PET film is well suited for a broad range of industrial, electronic, and automotive applications. It is fully recyclable and can be easily reprocessed into many other products for many different applications. However, unlike paper and other cellulose products, PET does not readily decompose. However, biodegradable additives are available that enhance the biodegradation of this plastic without affecting the physical properties.

The most important polyester film is biaxially oriented PET or BOPET.1 In comparison to other common plastic films, it has better retention of physical properties over a fairly wide temperature range of about -70°C to 100°C.

Despite its higher price, BOPET has found many high volume applications that require this stronger and dimensionally stable film. A major drawback of BOPET is the higher manufacturing costs and higher capital investment in equipment.

We Shandong huisenyuan New Nanomaterials  produce APET rigid film sheet for food packaging, blister packaging , PET film sheet for folding box, PET film sheet for anti-fog face-mask since 1995, our techinicians have 15years experience in the PET rigid film feild, so quality can be assured, and we have 5 production lines for the APET rigid film, so the delivery time can be assured.
