We usually come into contact with the pharmaceutical, food, daily chemical, and other industries for packaging which will generally choose chemical aluminum foil packaging. So it seems that the wide application of the product can meet the needs of modern life and production. For example, in the aerospace industry, the insulation and waterproof layers of liquid fuel tanks such as aircraft rotors, rockets and satellites are inseparable from aluminum foil, as well as chemical aluminum foil bags. In addition to this industry, the bags can also be used in the textile, vehicle, shipping building industry. In a word, chemical engineering aluminum foil bags can be found everywhere.
