The work aims to summarize the relevant literatures on the synthetic process, application progress and excellent barrier properties and other properties of polyvinylidene chloride (PVDC) in recent years, so as to provide a reference for the related research. PVDC was used as the key word to refer to the related literatures on the synthesis, properties and application of PVDC at home and abroad in recent years for organization and analysis. PVDC is mainly composed of emulsion polymerization and suspension polymerization. Its most prominent performance is excellent barrier properties. It is widely applied in the field of packaging with higher requirements of barrier properties, such as food, medicine, military products, etc. China's PVDC material has just begun to enter the market; therefore, there are great market application prospects.
