With the development of packaging technology, the aluminum alloy of toothpaste packaging materials has developed from 1060 alloy to 8079 alloy, 8011 alloy, etc., and the production process of toothpaste tubes has also changed greatly. At present, the commonly used alloys for aluminum foil for toothpaste tubes are 8011 and 8079, and the thickness is generally 0.016-0.04mm.
Application of aluminum foil in toothpaste tubes:
1. Good printing performance. After PE coating and printing, toothpaste tube foil can be widely used in the packaging of daily necessities such as cosmetics, medicines, food, detergents, etc.
2. Tube packaging is economical, convenient, and easy to pack, suitable for containing emulsions and colloids.
3. Packaging foil has the advantages of heat insulation, easy to break, and cleaning.
Aluminum foil toothpaste tube manufacturing process:
1. Material selection: Select high-quality aluminum foil (8011/8079) and composite materials such as polyethylene (PE) and polypropylene (PP). The thickness of the aluminum foil is generally 20~30 microns to ensure barrier properties and mechanical strength.
2. Composite processing: The aluminum foil is pressed with other materials through a composite process to form a multi-layer structure. Common composite methods include co-extrusion composite, adhesive lamination, etc.
3. Tube forming: The laminated multi-layer material is rolled into a cylindrical shape, and then the seams are bonded together using heat or adhesive to form a basic tube structure.
4. Printing and sealing: Print brand logos, product information and other information on the surface of the hose, then seal or crimp one end of the hose, and seal the other end after filling the toothpaste.
