How is the sealing performance of the 2.8ml aluminum empty click concealer tube? Can it effectively prevent product leakage or deterioration?

As a common cosmetic packaging container, the sealing performance of the aluminum concealer tube is one of the important factors to ensure product quality and safety. In practical applications, the 2.8 ml aluminum tube body is usually used for the packaging of semi-solid or paste products, such as concealer, eye gel, hand cream, wrinkle remover, etc. These products have high requirements for sealing performance because they are easily affected by air, moisture, light and microbial contamination, which may cause product deterioration, failure or adverse reactions.

Aluminum is a lightweight, corrosion-resistant, easy-to-process metal material with good barrier properties. The aluminum foil layer can effectively block the penetration of oxygen, moisture and light, thereby extending the shelf life of the product. In the aluminum tube body, this material property is fully utilized, and a uniform and tight tube wall structure is formed through precise stamping and stretching processes, thereby providing a good sealing foundation at the physical level.

In order to further improve the sealing performance, aluminum concealer tubes usually adopt the following sealing structure designs:

Threaded sealing structure: The tube mouth adopts internal and external thread design, and the initial sealing is achieved by tightening the cap. This structure is simple and reliable, and is suitable for daily use scenarios.

Rubber or silicone sealing ring: In addition to the threaded structure, an elastic sealing ring (such as an O-ring) is usually added to enhance the sealing effect. When the cap is tightened, the sealing ring is squeezed and deformed to form a tight contact surface to prevent liquid leakage.

Double-layer sealing structure: Some high-end products will adopt a double-layer sealing design, that is, two layers of sealing layers are set at the tube mouth, the first layer is a threaded seal, and the second layer is an elastic sealing ring. This double protection mechanism can effectively prevent air and moisture from entering, and also prevent liquid from overflowing from the tube mouth.

The sealing of aluminum concealer tubes depends not only on the design, but also on the manufacturing process. In the production process, it usually goes through the following key processes:

Stamping: The aluminum foil material is processed into a tubular structure through precision stamping to ensure that the tube wall thickness is uniform and there are no obvious defects.

Surface treatment: The tube body is surface treated by anodizing, spraying or electroplating to enhance its corrosion resistance and aesthetics, and also improve the adhesion of the sealing part.

Glue injection and sealing: Inject hot melt glue at the tube mouth or use other adhesives for sealing to ensure a firm connection between the cap and the tube body to prevent liquid leakage.

Quality inspection: Before leaving the factory, each aluminum tube will be tested for sealing, such as using a pressure tester to check whether there are no bubbles within 5 seconds under a pressure of 0.2MPa. In addition, drip tests and vacuum tests will be performed to ensure that the sealing performance meets the standard requirements.

The sealing of aluminum concealer tubes is not only suitable for daily cosmetics, but also for some products with high requirements for hygiene and stability, such as:

Medicinal ointment: used to treat skin inflammation, eczema and other diseases, with extremely high sealing requirements to prevent bacterial contamination.

Eye care products: such as eye gel, eye cream, etc., have high requirements for product purity and stability.

Products for children: such as children's hand cream, nail polish, etc., need to prevent children from accidentally ingesting or contacting unclean substances.

High-end skin care products: such as wrinkle removers, essences, etc., have high requirements for the active ingredients and stability of the products.

In addition to functional advantages, aluminum concealer tubes also have certain advantages in terms of environmental protection. Aluminum is a recyclable material with a high recycling rate, which helps reduce resource waste and environmental pollution. In addition, the lightweight design of aluminum packaging also helps reduce transportation costs and carbon emissions.
