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

Plastic hoses commonly used in cosmetic packaging can be divided into aluminum-plastic composite hoses, all-plastic composite hoses and plastic co-extruded hoses according to material application and processing technology. . Aluminum-plastic composite hose is a kind of packaging container that is co-extruded with aluminum foil and plastic film and processed into a pipe by a special pipe-making machine. Aluminum-plastic composite hoses are mainly used for cosmetic packaging in beauty salons 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. Aluminum-plastic composite hose has the characteristics of high barrier properties. Aluminum foil has barrier properties such as light blocking, oxygen blocking, and water blocking. Prevent external substances from invading the cosmetics in the beauty salon, prevent the cosmetics from oxidizing and deteriorating, and prevent the cosmetics or cosmetics from spreading out through the hose, thereby ensuring the quality of the cosmetics in the beauty salon. However, due to the use of aluminum foil, aluminum-plastic composite hoses have many disadvantages, such as invisible content, poor environmental protection, poor resilience, lower composite strength than all-plastic composite hoses, and easy delamination. . 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. Compared with aluminum-plastic composite pipes, all-plastic composite pipes have better environmental performance and convenient recycling. Better elasticity ensures that after the cosmetics are squeezed, the hose can quickly return to its original shape and always maintain a beautiful and normal appearance. Due to the composite process of the plastic board, printing decoration can be diversified. Flexo printing can be selected according to the needs of reasonable size, gravure printing can be selected according to the complexity of the drawing, or surface printing or internal printing can be selected according to functional requirements. According to the characteristics of cosmetics in beauty salons and the needs of different consumers, all plastic composite hoses can be made into different colors, such as colorless, transparent, transparent, opaque, etc., which will bring strong visual impact to consumers. But the disadvantage is that all-plastic barrier-proof composite hoses are usually used in the packaging of middle and low-end cosmetics because there are side seams in the tubes.
