Product Summary of Polyethylene Terephthalate (PET)

Polyethylene Terephthalate (PET) is an engineering thermoplastic available as semi-crystalline opaque and amorphous fully transparent. It has superb gas barrier properties, particularly against oxygen and carbon dioxide, which helps to explain its use in bottles for carbonated drinks. In general it has good resistance to mineral oils, solvents and acids, but not to bases.

The semi-crystalline version has good strength, ductility, stiffness and hardness, and coincidentally also includes many of the clear transparent films unless specified as APET (amorphous PET). It also has very good machining characteristics and its food compatibility makes it ideal for use in food processing equipment.

Characteristics of Polyethylene Terephthalate (PET) include:

  • Good gas barrier properties
  • Good chemical resistance
  • Low moisture absorption
  • Food compatible
