Abstract： The technique of ATR （Attenuated Total Refraction）-FTIR analysis was adopted to identify the components of degradable plastic packaging. Plastic samples were analyzed by Infrared Spectroscopy. Through the analysis of the main absorption bands of degradable plastics PBAT and PLA， the characteristics of PBAT and PLA materials and their products were obtained. ATR infrared spectroscopy is used to identify the main materials of degradable plastic packaging， which is simple， fast and efficient.

Key words： infrared spectroscopy； degradable plastic packaging； identification method
