[0002] As people's environmental awareness increases, more and more paper-based packaging enters people's lives, and so does edible oil. The edge overlap of traditional roof boxes is similar to that of paper cups, and the paper section of the edge seal inside the box is soaked in edible oil. Due to the high permeability of edible oil, the edible oil will slowly penetrate into the paper material, causing damage to the paper section and reduced strength at the paper section, which in turn shortens the product shelf life and causes the edible oil to oxidize and change its taste.
