22-410 Aluminum Cap

The 22-410 aluminum cap is a commonly used sealing material, primarily used for sealing containers in industries such as pharmaceuticals, food, and cosmetics.

The 22-410 aluminum cap is a threaded aluminum cap, commonly used to seal various containers, especially for packaging products like cosmetics, pharmaceuticals, beverages, and chemicals.

22: Represents the outer diameter of the cap, which is 22 millimeters.
410: Represents the thread size, a specific standard for the thread type of the cap. The 410 thread is a commonly used thread size for small bottles and jars.

These caps are typically used for glass or plastic containers and are known for providing a secure seal to prevent leaks and protect the internal products. Depending on the application, they can be equipped with various lining materials (such as foam, pulp, or PE), offering different sealing performance.

22-410 Aluminum Cap Specifications

Model: 22-410
Material: High-quality aluminum alloy
Diameter: 22 millimeters (outer diameter)
Height: Varies slightly depending on the manufacturer's process
Color: Typically silver (natural color), can be colored as needed

The 22-410 aluminum cap is made by stamping aluminum alloy sheets, with commonly used alloy types including 8011-H14, 3003-H16, balancing strength and ductility to meet automation production requirements.

22-410 Aluminum Cap Structural Features

Edge Design: Features a rolled edge structure for easy mechanical capping.
Liner: Can be equipped with liners made of different materials (such as PE, PVC, or composite films).
Surface Treatment: Can undergo anodizing, spraying, or printing treatments.

22-410 Aluminum Cap Liner Options

Foam Liner: Commonly used for sealing liquid or air-sensitive products, such as perfumes, essential oils, or cosmetics. Foam liners provide excellent sealing and can compress to adapt to slight variations in bottle necks.
PE Liner: Often used for applications requiring chemical resistance and moisture-proof sealing, commonly used in pharmaceuticals, food, and beverages.
Pulp Liner: A natural fiber liner with good sealing performance, commonly used for products requiring eco-friendly solutions.
Silicone Liner: Offers higher resistance to temperature fluctuations, suitable for applications that demand higher performance, such as chemicals or high-performance cosmetics.

22-410 Aluminum Cap Performance Features

Sealing: Excellent leak-proof performance.
Corrosion Resistance: Good resistance to most chemicals.
Hygiene and Safety: Meets food and pharmaceutical packaging hygiene standards.
Easy to Open: Some designs feature pull rings or easy-tear structures.

22-410 Aluminum Cap Applications

Cosmetics: These caps are commonly used in the beauty industry for products like lotions, serums, and creams that require sealing.
Pharmaceuticals: Used for packaging pills, liquid medications, and even vitamin bottles, ensuring product integrity and preventing contamination.
Food and Beverages: They can be used for beverage bottles, sauces, or oils, where containers require safe, tamper-evident seals.
Chemicals: Used to seal containers for chemicals, cleaners, and solvents.

22-410 Aluminum Cap Manufacturing Process

Shaping Process

Stamping and Stretching: 0.22mm aluminum sheets are stamped into shape through multiple stages, with dimensional tolerance of ±0.1mm, ensuring a precise match with the bottle neck.
Embossing and Printing: Raised patterns are pressed onto the sides using a knurling machine, followed by high-precision flexographic printing, with UV curing to ensure strong adhesion.

Quality Control

Performance Testing: Includes torque testing (opening force 8-15N・m), drop testing (1.5-meter height without breakage), and weather resistance (salt spray test for 48 hours without corrosion).
Appearance Inspection: Automated vision systems detect defects like missing teeth or burrs, ensuring clear and complete threads.

22-410 Aluminum Cap Common Specifications

Screw Aluminum Bottle Caps 22/410 Smooth Surface: This is a 22mm diameter screw-type aluminum cap with a 410 thread, suitable for bottles with corresponding neck sizes. The cap has a smooth surface, which not only improves its aesthetic appeal but also makes cleaning easier and may reduce the chances of the cap being scratched during transportation and usage. It can be used in cosmetics, pharmaceuticals, food, and other industries for sealing glass or plastic bottles, ensuring the safety and sealing of the contents.
Silver Aluminum Cap 20-410 w/ PE Foam Liner: This cap has a 20mm diameter and uses the 410 thread standard. The cap is silver in color and features an aesthetically pleasing appearance, enhancing the visual appeal of the product. The cap is equipped with a PE (polyethylene) foam liner, which provides excellent compressibility, ensuring a tight seal when the cap is screwed on, preventing leakage, evaporation, or moisture absorption. PE foam liners also offer certain chemical resistance, making them suitable for a wide range of products such as acidic and alkaline substances, aqueous products, and cosmetics, though they are generally not recommended for hydrocarbon solvent packaging. Commonly used for plastic or glass bottles, it is often found in packaging for lotions, shampoos, and other cosmetics, as well as some food and pharmaceutical products.
20/410 Silver Aluminum Cap with Liner: Similar to the 20-410 silver aluminum cap, this cap has a 20mm neck diameter and a 410 thread design, with a silver color. It includes a liner, which could be made of materials like PE foam, aluminum foil, or pressure-sensitive liners. Different types of liners are suited for various applications and product requirements. For example, aluminum foil liners provide excellent barrier properties, making them ideal for products that require high sealing and moisture resistance. Pressure-sensitive liners automatically bond with the bottle neck when the cap is tightened, providing a good seal. This cap can be used for a variety of products that require sealed packaging, such as candies, seasonings, and cosmetics, providing excellent protection while also offering a silver appearance that enhances branding and marketability.
