What are the advantages and disadvantages of plastic hoses commonly used in cosmetic packaging?

Aluminum-plastic composite hose has the following advantages during use:
(1) High barrier properties, aluminum foil has barrier properties such as light barrier properties, oxygen barrier properties and water barrier properties. The ingredients are diffused to the outside through the hose, thus ensuring the quality of the cosmetic.
(2) Low cost. To achieve the same barrier performance, aluminum-plastic composite hoses use less material, lower cost and better economy than all-plastic composite hoses and plastic co-extrusion hoses.

Disadvantages of aluminum-plastic composite hoses: Due to the use of aluminum foil, aluminum-plastic composite hoses have many disadvantages, such as invisible contents, poor environmental protection, poor resilience, lower composite strength than all-plastic composite hoses, and easy delamination.
 
The advantages of all-plastic composite hose:
(1) Environmental protection. Compared with the aluminum-plastic composite hose, the all-plastic composite hose adopts an economical and easy-to-recycle all-plastic sheet, which can reduce the pollution of packaging waste to the environment. The recycled all-plastic composite hose can be produced after reprocessing. Relatively low-end product.
(2) Diversified colors. According to the characteristics of cosmetics and different consumer needs, the all-plastic composite hose can be made into different colors, such as colorless transparent, colored transparent, colored opaque, etc., bringing consumers a strong visual enjoyment. In particular, the transparent all-plastic composite hose can clearly see the color state of the contents, giving people a strong visual impact and greatly promoting consumers' desire to buy.
(3) Good resilience: Compared with the aluminum-plastic composite hose, the all-plastic composite hose has better resilience, which ensures that after the cosmetic is squeezed, the hose can quickly return to its original shape, and always maintains a beautiful, The appearance of the rules. This is crucial for cosmetic packaging.
 
Disadvantages of the all-plastic composite hose: The barrier property of the all-plastic composite hose mainly depends on the type and thickness of the barrier layer material. Taking EVOH as the barrier layer material for the all-plastic composite hose as an example, to achieve the same barrier property and The stiffness is about 20% to 30% higher than that of the aluminum-plastic composite hose. For a long period of time in the future, this will become the main factor restricting the full replacement of aluminum-plastic composite hoses by all-plastic composite hoses.
 
The main advantages of plastic co-extruded hoses:
(1) Since there is no side seal, the appearance is better than that of composite hoses, which is necessary for high-end cosmetic hose packaging.
(2) According to the different extrusion die, various shapes of extrusion hoses can be produced, such as oval, square, etc., to meet the needs of different consumers.
 
Disadvantages of plastic co-extrusion hoses: The production and processing technology of plastic co-extruded hoses is generally made first and then printed. For the printing process, the efficiency is low, the process is complex, and the difficulty is high.
 
Summary:
The plastic hose is hygienic and convenient to use, and its surface is bright and beautiful, so it has been widely used in the packaging of paste cosmetics, such as the packaging of facial cleanser, conditioner, hair dye, toothpaste and other products in the cosmetics industry, as well as in the pharmaceutical industry. Packaging of creams, ointments and other external medicines.
The plastic hose is economical and convenient to pack, easy to carry, and can return to its original shape and maintain a good appearance even with high-intensity all-over extrusion. The data shows that 60%~70% of the hoses are used in the cosmetics industry, 10%~15% of the hoses are used in the pharmaceutical industry, and about 5% are used in the food industry.
