The work aims to review the chemical recycle technology of plastic packaging waste in recent 5 years with polyolefin and polyethylene terephthalate (PET) as the research object, so as to provide reference for the development trend of plastic packaging waste recycle technology. The chemical recycle methods, common catalysts and reaction devices of polyolefin and PET packaging wastes were clarified by collecting and sorting relevant literature. The effects of catalyst, reaction device and reaction temperature on product yield and composition were analyzed. In the short term, the flexible packaging materials will still be dominated by traditional petroleum-based materials such as polyolefin and polyester. Chemical recycle is an important means for recycling waste plastics. The improvement of traditional catalysts, the development of new catalysts and the optimization of reaction devices will be the focus of future research in this field.
