Comparison of advantages of aluminum-plastic composite hose and all-plastic composite hose

. Aluminum-plastic composite hose Aluminium-plastic composite hose is a kind of packaging container that is co-extruded with aluminum foil and plastic film and processed into a tube by a special tube-making machine. The typical structure is PE PE + EAA Al PE + EAA PE. Aluminum-plastic composite hoses are mainly used for packaging cosmetics that require high hygiene and protection. The barrier layer is generally aluminum foil, and the barrier layer depends on the size of the pinholes of the aluminum foil. With the continuous improvement of technology, the thickness of the aluminum foil shielding layer in the aluminum-plastic composite hose has been reduced from μm to μm or even μm, which greatly saves resources. The aluminum-plastic composite hose has the following advantages in use. () High barrier properties Aluminum foil has barrier properties such as light resistance, oxygen resistance, and water resistance. On the one hand, it can prevent foreign substances from invading the cosmetics, prevent the cosmetics from oxidizing and deteriorating, and prevent the moisture and flavor in the cosmetics from spreading out through the hose, so as to ensure the quality of the cosmetics. () Low cost In order to achieve the same barrier performance, aluminum-plastic composite hoses have the advantages of less material, lower cost, and better economy than all-plastic composite hoses and plastic co-extruded hoses. . All plastic composite hoses All plastic composite hoses are made of plastic. Plastic composite hoses can be 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 fast-consuming cosmetics; the barrier layer of the all-plastic barrier composite hose can be multi-layer composite materials containing EVOH, PVDC, oxide coating pet, etc., due to the side seams of the tube. The typical structure of plastic barrier composite hose is PE PE EVOH PE PE. The advantages of plastic composite hoses are as follows. ()Environmental protection Compared with aluminum-plastic composite hoses, all-plastic composite hoses use all-plastic sheets, which are economical and easy to recycle, which reduces the environmental pollution caused by packaging waste. The recycled all-plastic composite hoses can be used for two purposes. Sub-processing to produce relatively low-quality products. ()Diversity of colors According to the characteristics of cosmetics and the needs of different consumers, all plastic composite hoses can be made into different colors, such as colorless, transparent, transparent, opaque, etc., which brings strong visual enjoyment to consumers . In particular, the transparent all-plastic composite hose can clearly see the color status of the content, giving a strong visual impact, and greatly increasing consumers' desire to buy. ()Good resilience: Compared with aluminum-plastic composite hoses, all-plastic composite hoses have better resilience, which ensures that the hose can quickly return to its original shape after squeezing cosmetics, and always maintain a beautiful and standardized appearance. This is very important for cosmetic packaging.
