Recently, the paper-based composite packaging technology applied abroad has made new progress. Its types are film type, liner bag type, embedded type, liquid type and so on. Since the oil molecules are extremely small, the main technical difficulty in developing paper-based composite packaging is to solve the seepage prevention. Recently, Japanese researchers have developed a boxed cooking oil compound carton that has been very successful. The structure of the composite paper is based on paper, and is made of aluminum-plastic 6-layer composite. As the composite layer has aluminum foil, its performance is better than that of plastic bottles and glass bottles. This kind of composite carton that can hold oil is safe, light and beautifully printed.
