Aluminum-plastic composite hose has excellent barrier properties, strong corrosion resistance and good printing adaptability, so it is widely used in the packaging of toothpaste, cosmetics and some industrial products. For toothpaste packaging, aluminum-plastic composite tubes have completely replaced traditional aluminum tube packaging in 2002. China's toothpaste output is 3 billion pieces per year, and the demand for aluminum foil for toothpaste packaging is 3,000 tons. In addition, the demand for aluminum-plastic composite hoses in other fields has also increased to varying degrees, such as medicine and health products, beauty cosmetics, condiments, industrial supplies, etc.
