[0002] A container refers to a basic device that is used to hold materials and is mainly composed of a shell. It is usually used to store liquid, solid or fluid materials, such as disposable food containers, which generally refer to disposable paper cups, paper lunch boxes or other paper containers, especially disposable paper cups and paper lunch boxes. Disposable paper cups are a drinking tool that is mostly used in homes and public places. Paper lunch boxes are commonly used containers for takeout packaging. Paper cups and paper lunch boxes have good portability and usability, but paper cups and paper lunch boxes themselves have poor waterproof properties. For this reason, a polyethylene waterproof film is applied to the inner wall of the paper cup in industrial production. However, if the selected material is not If the polyethylene is not good or the processing technology is not up to standard, it may be oxidized into carbonyl compounds during the process of hot melting or applying it to the paper cup. Carbonyl compounds are not easy to volatilize at room temperature, but when the inner wall of the paper cup or paper lunch box contacts hot water or hot oil, the carbonyl compounds may volatilize, so people will smell a strange smell. Drinking water from such paper cups for a long time will cause certain harm to the human body. In addition, general paper cups and paper lunch boxes have poor oil resistance. If oil is contained for a long time, the oil will easily penetrate into the inside of the paper cup and paper lunch box, affecting the user experience.
