Cosmetic aluminum plastic tube

Aluminum-plastic composite hoses have been very popular in recent years, mainly because they are processed into sheets by aluminum foil and plastic film by co-extrusion compounding process, and then processed into hose packaging containers by special pipe making machine, which is especially suitable for hygienic , cosmetic packaging with high barrier performance requirements. With the continuous development of technology, the thickness of the aluminum foil barrier layer in the aluminum-plastic composite hose has been reduced from 40 μm to 12 μm or even 9 μm. Aluminum foil has excellent barrier properties such as light opacity, oxygen barrier and water repellency.
On the one hand, it can prevent foreign substances from invading the inside of cosmetics and cause oxidative deterioration of cosmetics. On the other hand, it can prevent moisture or glycerin in cosmetics from passing through soft. The tube spreads to the outside world, thus effectively ensuring the quality of the cosmetics. More importantly, cosmetic packaging is easier to achieve high-brightness through structural and process adjustments, especially for tube-in-tube packaging.
