Basic knowledge of cosmetic hoses

Cosmetic hoses are loved by many cosmetics production brands because of their light weight, easy to carry, strong and durable, recyclable, easy to squeeze, good processing performance and printing adaptability. They are widely used in the packaging of skin care products and other cosmetics. In the previous article, there was an article about cosmetic hoses. There was a brief introduction to the types, characteristics, and processes of the hoses, but due to the limitations of the collected information, more detailed information could not be provided. The editor cannot tolerate articles that cannot solve the problem, so he made up his mind to work hard to collect information about cosmetic hoses and compiled them into this article, hoping to help everyone better understand all aspects of cosmetic hoses:

1. Characteristics of cosmetic plastic hoses

At present, the commonly used plastic hoses in cosmetic packaging mainly include aluminum-plastic composite hoses, all-plastic composite hoses and plastic co-extruded hoses, which can meet various requirements of cosmetic packaging, such as hygiene and barrier properties.

1. Aluminum-plastic composite hoses

Aluminum-plastic composite hoses are made of aluminum foil and plastic film through co-extrusion composite process into sheets, and then processed into a tube by a special tube making machine. A typical structure is PE/PE+EAA/AL/PE+EAA/PE. Aluminum-plastic composite hoses are mainly used to package cosmetics with high requirements for hygiene and barrier properties. The barrier layer is generally aluminum foil, and its barrier property depends on the pinhole degree 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.

Aluminum-plastic composite hoses have the following advantages during use.

(1) High barrier properties. Aluminum foil has barrier properties such as light barrier, oxygen barrier and water barrier. On the one hand, it can prevent foreign substances from invading the inside of cosmetics and prevent cosmetics from oxidation and deterioration. At the same time, it can also prevent moisture or fragrance in cosmetics from diffusing to the outside through the hose, thereby ensuring the quality of cosmetics.

(2) Low cost. To achieve the same barrier properties, aluminum-plastic composite hoses use less materials, lower costs and better economy than all-plastic composite hoses and plastic co-extruded hoses.
