Top Five Aluminum Coil Sheet For Pilfer Proof Caps

Aluminum coil sheet for pilfer proof caps typically refers to aluminum alloy coil sheets specifically manufactured for use in bottle caps, which have specific physical and chemical properties to meet anti-theft and sealing requirements. Pilfer proof caps are widely used in the beverage, pharmaceutical and cosmetic industries to ensure product security and integrity.

The selection of aluminum coil sheet for pilfer proof caps is based on the material’s processability, strength, corrosion resistance, and ability to meet specific application requirements, such as high-temperature cooking or sterilization. The following are a few of the aluminum closure sheet grades commonly used for pilfer proof caps:

• 8011 aluminum coil sheet:

– Mainly used for white wine caps, red wine caps and PP/ROPP bottle caps.

– Characterized by good stamping depth, good oxidation effect, good deep-drawn performance and low ear rate.

– Suitable for direct stamping cap making method, thickness range is 0.15-0.27mm.

• 3105 aluminum coil sheet:

– Belongs to the AL-Mn alloy series, with good anti-rust properties.

– Aluminum content is 98%, with 0.3% copper element added to improve conductivity.

– Cannot be heat treated, but its good machinability makes it an option for anti-theft bottle cap material.

• 1060 aluminum strip coil:

– Industrially pure aluminum with an Al content of at least 99.6%, suitable for stamping and forming processes.

– It has the hardness and formability required for bottle caps, and is commonly used in the cosmetic industry, but also seen in the pharmaceutical industry.

– Thickness usually between 0.17mm-0.5mm, width 449mm-796mm.

• 5052 aluminum coil sheet:

– Contains magnesium and chromium, providing better mechanical properties and corrosion resistance.

– Higher strength and easy to process, suitable for applications requiring high environmental conditions.

• 1100 aluminum coil sheet:

– Industrially pure aluminum with excellent corrosion resistance and good malleability.

– It may be used for anti-theft bottle caps where high conductivity or low density characteristics are required.

Depending on the application and specific requirements, manufacturers may choose aluminum coil sheet in different states (e.g. H14, H16, H18) and specifications. For example, 8011-H16 aluminum foil may be preferred for situations where good deep-drawing properties are required, while 1060-H24 aluminum sheet may be preferred for applications requiring higher hardness and formability.

The choice of aluminum coil sheet for pilfer proof caps depends not only on their physical and chemical properties, but also on factors such as cost-effectiveness and compatibility with production processes. Therefore, in practice, manufacturers usually determine the most suitable material based on their production line characteristics and product quality standards.
