With the rapid development of the takeout ordering industry and the sharp increase in the demand for lunch boxes, the commonly used takeout boxes have developed from the previous polyethylene lunch boxes to the current PE lunch boxes. In order to save energy and environmental protection, paper lunch boxes are currently used in the market, but the current paper lunch boxes have poor thermal insulation performance, and because of the particularity of Chinese food, the dishes often contain oil and water and high outlet temperature, Therefore, the lunch boxes often become soft, deformed and leak oil, which is not conducive to the wide promotion and application of paper lunch boxes.
