• Pull Tab Stock: 5182. High-magnesium alloy with high strength to prevent breakage during opening.

Key Indicators:

• Earring Rate: ≤3%, reducing scrap and improving material utilization.
• Flatness Control: Excellent flatness with no obvious waves; thickness tolerance within ±0.005mm.
• Standards: Complies with EN 541, YS/T435-2009, and other can industry standards.

Closure Sheets & Bottle Cap Material

Used for various aluminum ROPP caps (Roll-on Pilfer Proof), easy-peel lids, and screw caps for glass and plastic bottles.

Application Fields:

• Anti-theft caps for spirits (Whisky, Baijiu).
• Beverage and oral liquid caps.
• Easy-peel off ends (POE) for milk powder.
• Cosmetic caps.

Specifications:

• Common Alloys: 8011, 3105, 3003, 1060
• Tempers: H14, H16 (Semi-hard, suitable for deep drawing)
• Thickness: 0.15mm - 0.30mm
• Surface Process: Chromated, DOS Oiled, Color Coated (Lacquered).

Aluminum Collapsible Tubes

Tubular containers made via cold extrusion or rolling, offering excellent airtightness.

• Applications: Ointment tubes, toothpaste tubes, hair dye tubes, glue, and lubricant tubes.
• Raw Material: 1050, 1070 pure aluminum slugs; high purity and softness for instant extrusion forming.
