Aluminum-plastic composite tube 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 tubes are mainly used for packaging cosmetics that require high hygiene and barrier properties. The barrier layer is generally aluminum foil, and its barrier properties depend 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 tube has been reduced from the traditional 40μm to 12μm, or even 9μm, which greatly saves resources.
The aluminum-plastic composite tube has the following advantages during use.
The barrier properties such as resistance and water resistance, on the one hand, can prevent foreign substances from intruding into the cosmetics and prevent the cosmetics from oxidizing and deteriorating. At the same time, they can prevent the moisture or fragrances in the cosmetics from diffusing to the outside through the tube, thereby ensuring the quality of the cosmetics.
To achieve the same barrier properties, aluminum-plastic composite tubes use less materials, lower cost, and are more economical than all-plastic composite tubes and plastic co-extruded tubes.
