What are the characteristics of the outer cover material of Aluminum Emulsion Jar?

The outer cap of Aluminum Emulsion Jar, especially the outer cap made of aluminum oxide, has rich and unique characteristics. These characteristics together constitute its significant advantages as a high-end cosmetic packaging material. Due to its metallic properties, the aluminum outer cover has extremely high tensile strength and compressive strength, which can maintain the structural integrity under various transportation and storage conditions and effectively prevent damage or deformation caused by external forces. The density of aluminum is about 1/3 of copper and 1/5 of iron. This makes the aluminum outer cover greatly lighter in weight while ensuring sufficient strength, making it easier for consumers to carry and use, and also reducing the cost of packaging and transportation.
After the aluminum outer cover is anodized, a hard and dense aluminum oxide film will be formed on the surface. This film has extremely high corrosion resistance and chemical stability, and can effectively withstand acid, alkali, salt spray and other harsh environments. Corrodes and protects lotions and other cosmetics from contamination. The aluminum oxide material complies with food-grade safety standards and will not react chemically with lotions and other cosmetics, ensuring the purity and safety of the product.
The aluminum outer cap and the bottle body are usually connected using threads or buckles to ensure a tight fit between the two and effectively prevent leakage of lotions and other liquids. The aluminum oxide film not only has excellent corrosion resistance, but also effectively blocks the intrusion of moisture and moisture, keeping the environment inside the bottle dry and extending the shelf life of the product.
The aluminum outer cover can withstand higher temperatures without deformation or damage, which allows it to maintain structural integrity and sealing during transportation and storage in high-temperature environments. Aluminum has good thermal conductivity and can quickly disperse heat to the entire cover surface, thus avoiding damage caused by local overheating.
The aluminum outer cover can be obtained in rich colors and patterns through the anodizing coloring process to meet consumers' personalized needs for product appearance. Spraying, laser engraving and other processes can also be used to further decorate and beautify the outer cover to enhance the added value and market competitiveness of the product.
Aluminum is a recyclable metal resource. The aluminum outer cover can be recycled and reused after being discarded, reducing resource waste and environmental pollution. As consumers become more aware of environmental protection, the environmental protection of Aluminum Emulsion Jar and their outer caps has become an important competitive advantage. By using recyclable materials and reducing packaging waste, Aluminum Emulsion Jar and their outer caps comply with the concept of modern green packaging.
