Aluminum Alloy 1100 Aluminum Closure Sheet for Bottle Caps | Thickness 0.15–0.25 mm | Width 500–1000 mm | Color Lacquered & Lubricated

Introduction                                                

The 0.15–0.25 mm 1100 aluminum closure sheet (color lacquered & lubricated) is the most widely used economical pure-aluminum grade worldwide for twist-off caps (ROPP / roll-on pilfer-proof), crown caps, beverage bottle lids, jar caps and easy-open closures in the beverage, beer, soft drink, energy drink, spirits and food jar markets.

With aluminum purity ≥99.00%, 1100 provides:

Outstanding deep-draw & stamping performance in thin gauges

Excellent lacquer adhesion & uniform color coverage

Superior lubricated surface → high-speed cap forming & low tool wear

Lowest cost per cap among closure alloys while maintaining 100% food safety

Lacquer & lubrication system:Color lacquer (20–30 μm polyester or epoxy-based) on one side

Food-grade lubricant on both sides or top side only

Compliance: FDA 21 CFR 175.300, EU 10/2011, GB 4806, Japan MHW

Colors: gold, silver, red, blue, black, custom Pantone/RAL matches

FAQ (USA/Europe/Middle East/Asia Buyers)

Q1: Why choose 1100 over 5182 or 8011 for bottle cap stock?

A: 1100 is significantly lower cost (30–50% less than 5182), has excellent deep-draw performance for twist-off & ROPP caps, and superior lacquer adhesion/color uniformity. 5182 is used for stay-on-tab can ends; 8011 is more common for flexible foil lids. 1100 is the standard for most beverage twist-off & crown cap applications.

Q2: What lacquer thickness & adhesion performance can be expected?

A: 20–30 μm lacquer with 5B cross-cut adhesion (ASTM D3359). No peeling during high-speed forming or capping. We provide adhesion & bend test reports for each batch.

Q3: Can you provide full FDA / EU 10/2011 / GB 9685 compliance & migration test reports?

A: Yes — complete certificate package + third-party migration/leachability reports (SGS/Intertek). Supports full regulatory submissions for beverage & food contact.

Q4: Minimum order quantity & lead time for custom colors or lubrication levels?

A: MOQ 3–5 tons (depending on width/color); standard gold/silver 15–25 days; custom Pantone/RAL or lubrication adjustment 25–35 days. Sample coils free with freight collect.

Q5: How does 1100 perform in high-humidity / tropical bottling plants?

A: Excellent — passes 40 °C / 90% RH accelerated aging for 24–36 months with no lacquer cracking or corrosion. Tropical storage & humidity chamber data available.

Q6: Is 1100 suitable for high-speed capping lines without jamming? A: Yes — uniform thickness tolerance (±0.005 mm) & consistent lubrication ensure smooth feeding & capping at 1200–2000 caps/min. We provide trial coils & capping line recommendations.
