Abstract: The recycling method, determination methods, and development trend of poly(ethylene terephthalate) (PET) in both domestic and international were introduced. The recycling methods could be categorized as physical and chemical ones. The determination methods included gas chromatography, gel permeation chromatography, differential scanning calorimetry, and thermogravimetric analysis. It was urgent to establish the determination standards for recycled plastic food packaging materials and its relevant regulations.

Key words: poly(ethylene terephthalate), recycling method, detecting technology, development situation, regulation
