Cooking oil is now mainly packagedby cans and PET bottles in China. However, there are problems of serious illegally refilling waste cooking oil, limited shelf life and high costs. In this paper, the structure of the Bag in Box (BIB), the advantages of the packaging for the cooking oil, the existing problems, and the prospect of the application in the packaging of the cooking oil were reviewed. BIB has been widely used in the packaging of various liquid products, which can be used in cooking oil to save raw materials and costs, improve the shelf life, and exclude illegally refilling waste cooking oil, etc.. At present, because of the limit of technical level, BIB usage also existed leakage caused by malposition pressing cap into neck in the filling process, pinhole leakage caused by stab of film by sharp edges and burrs in the filling process, and pinhole leakage caused by knead and rub in the transport process etc. Therefore, the quality standards need to be further improved. Domestic cooking oil market is huge, with further strengthen of the policy of the provinces and municipalities to prohibit bulk cooking oil in the future, and the BIB packaging cooking oil market may usher in substantial growth.
