The work aims to summarize the research status of oil-proof packaging paper in food packaging, and to provide a reference for further expanding the research methods and applicable fields of oil-proof packaging paper. By summarizing the domestic and foreign research results and current situation, the paper focused on the in-machine oil-proof paper and post-process oil-proof paper, and analyzed the method and mechanism of achieving paper oil-proofing. Oil-proof packaging paper was often used in the packaging of various fat-containing articles, so it was often involved in the fields such as food, industry, and medical treatment. Its research methods, implementation methods, and experimental results were particularly important. Although there were many types of oil-proof packaging paper, and the research on biomass oil-proof paper was endless. Food safety, recycling, degradation and cost issues have not been able to be considered at the same time. Oil-proof packaging paper and paperboard have received extensive attention in food packaging. Particularly, biomass oil-proofing agent has great the research potential in this field.
