What material is the cosmetic tube made of?
1. Aluminum tube made of pure aluminum
The manufacturing process is simple, and the inner sprayed hose is added, which does not react with the content and does not change the performance of the product. The hose with tail glue has good sealing characteristics and has a more sufficient sealing protection effect on the product.
2. Aluminum-plastic composite tube
The aluminum-plastic composite hose is a kind of packaging container made of aluminum foil and plastic film through a co-extrusion composite process, and then processed into a tube by a special pipe-making machine. Its typical structure is PE/PE+EAA/AL/PE +EAA/PE. Aluminum-plastic composite hose is mainly used for packaging cosmetics that require high hygiene and barrier properties. The barrier layer is generally aluminum foil, and its barrier property depends on the pinhole of the aluminum foil. With the continuous improvement of technology, the thickness of the aluminum foil barrier layer in the aluminum-plastic composite hose has been reduced from the traditional 40μm to 12μm, or even 9μm, which greatly saves resources.
3. All-plastic composite tube
All-plastic composite hoses are made of plastic components, and are divided into two types: all-plastic non-barrier composite hoses and all-plastic barrier composite hoses. The all-plastic non-barrier composite hose is generally used for the packaging of low-grade and fast-consuming cosmetics; the all-plastic barrier composite hose is usually used for the packaging of medium and low-grade cosmetics due to the side seams in the pipe manufacturing. The barrier layer can contain EVOH, PVDC, and oxide coatings. Multi-layer composite materials such as PET. The typical structure of all-plastic barrier composite hose is PE/PE/EVOH/PE/PE.
