Polyethylene terephthalate (PET) is a remarkably balanced material for beverage containers and food packaging with required mechanical and barrier properties. However, to contain tasteful beverages such as beer, fresh juice, and wine, the original barrier property of PET is not yet sufficient. Additionally, for the eco-friendly use of PET by reducing the thickness of PET bottles or PET films, which would lead to a decrease in the consumption of PET resins, the mechanical properties of PET should be enhanced. In this chapter, the backgrounds of PET-based packaging and its requirements will be summarized and discussed regarding the industrial applications of PET. In consequence, two different approaches to improve the mechanical and the barrier properties of PET for food packaging were introduced: thin-film coating for the effective improvement of the barrier properties, and nanofiller blending for the enhancement of the barrier and the mechanical properties of PET.
