Aluminum anti-theft caps are primarily made of aluminum alloy material. Their unique anti-theft design effectively prevents secondary opening, ensuring product security and sealing performance. As a result, they are widely used in the food, beverage, pharmaceutical, cosmetics, and chemical industries. The common materials for aluminum anti-theft bottle caps are 8011 aluminum alloy and 3105 aluminum alloy, both of which offer excellent rust resistance, moderate strength, and good ductility, making them suitable for stamping and stretching processes in cap manufacturing.

Common Materials and Characteristics of Aluminum Anti-Theft Caps

8011 Aluminum Alloy

Main Components: Primarily aluminum (Al) with small amounts of iron (Fe) and silicon (Si)

Features:

(1)Moderate strength

(2)Excellent corrosion resistance

(3)Good plasticity, suitable for deep drawing processes

Applications: Commonly used for beverage, liquor, and pharmaceutical bottle caps

3105 Aluminum Alloy

Main Components: Primarily aluminum (Al) with manganese (Mn) and magnesium (Mg) elements

Features:

(1)Higher strength compared to 8011

(2)Excellent corrosion resistance

(3)Suitable for high-end bottle cap requirements

Applications: Mostly used for pharmaceutical and cosmetic bottle caps

Advantages of Aluminum Anti-Theft Caps

1.Strong Anti-Counterfeiting Features: Designed with an anti-theft ring that cannot be restored after opening.
2.Excellent Sealing Performance: Ensures no leakage or spoilage during storage and transportation.
3.Superior Corrosion Resistance: Ideal for food and pharmaceutical packaging, resistant to rust.
4.High Plasticity: Suitable for stamping and deep drawing, customizable in color and printing designs.
5.Environmentally Friendly & Recyclable: Aluminum materials can be recycled, meeting environmental protection standards.

Quality Inspection Standards for Aluminum Bottle Cap Materials

1.The coil edges must be neat, without cracks, burrs, curled edges, serrated edges, or dents.
2.The total misalignment of the coil should be <2mm, and the tapering should be <5mm.
3.When the strip is freely uncoiled on a platform, the wave height should be <3mm, with no more than three waves per meter.
4.The surface must be smooth and clean, free of oil stains, wrinkles, or serious pressure marks.
