Toothpaste, as an essential oral health care product in People’s Daily life, is closely related to everyone’s life. The amount of toothpaste used in China is more than 5 billion per year, and various types of functional drug toothpaste emerge in an endless stream every year. As the packaging of toothpaste, the tube packaging is also in continuous development.

The tube packaging of toothpaste made of lead and tin materials was not used until the 1960s, but the aluminum tube packaging has a rough appearance, and for the drug toothpaste, the disadvantages of the aluminum tube will be exposed. Some of the ingredients in the medicated toothpaste may react with the aluminum tube causing spots on the tube and quality problems. In order to solve this problem, it is also necessary to spray protective coating inside the aluminum tube to isolate the aluminum tube from direct contact with the toothpaste paste. However, uneven spraying and high cost limit the development of the aluminum tube. Seeking for new packaging methods is the only way to solve this problem.

In the 80 s, using composite sheet as appeared on the international toothpaste tube production of new technology, until now it’s still the mainstream way of toothpaste tube packing, The composite material used in the aluminum plastic composite hose is mainly produced by plastic and aluminum foil composite packaging materials, the surface is plastic, the middle barrier layer for aluminum foil, and toothpaste paste contact is the inner layer of material, so that the composite hose is both sanitary and beautiful, will not react with the content.

In recent years, with the development of research on high barrier plastic materials, the use of high barrier performance of plastic barrier layer meters instead of aluminum foil production of composite sheet preparation of plastic composite tube packaging, has also been rapid development.
