30x60mm Aluminum Bottle Caps for Wine with Anti Spill Design
A premium sealing solution for wine producers, bottlers, event planners, and home enthusiasts — the 30x60mm Aluminum Bottle Cap with Anti-Spill Design combines reliable containment, elegant presentation, and practical spill prevention.
The 30x60mm Aluminum Bottle Cap is an aluminum alloy screw/press-fit cap (depending on inner liner choice) engineered specifically for wine bottles. The cap diameter and height (30 mm × 60 mm) make it suitable for a variety of neck finishes and provide a substantial, premium tactile feel. The anti-spill design integrates an inner stopper and flow barrier to reduce leakage and drip during pouring, transport, and storage.
selling points:
- Anti-spill inner geometry to minimize drips and leakage
- Corrosion-resistant aluminum alloy construction
- Compatible with standard wine bottle necks (check specifications)
- Multiple liner options for different wine types (natural cork, synthetic, and inert liners)
- Elegant finish options: brushed, polished, colored lacquers, and printed branding

Chemical Composition (Typical Aluminum Alloy used)
These caps are commonly manufactured from commonly used beverage-grade aluminum alloys such as AA3104-H19 or AA5052-H34 depending on forming and corrosion resistance requirements. Typical composition ranges are provided below for reference.
| Element | AA3104 (typical wt%) | AA5052 (typical wt%) |
|---|---|---|
| Aluminum (Al) | Balance (~97.0–99.0) | Balance (~95.0–97.5) |
| Manganese (Mn) | 0.8–1.3 | 0.15–0.5 |
| Magnesium (Mg) | 0.03–0.20 | 2.2–2.8 |
| Silicon (Si) | 0.5–1.0 | 0.25 |
| Iron (Fe) | 0.3–0.7 | 0.4 |
| Copper (Cu) | 0.03 | 0.1 |
| Zinc (Zn) | 0.03 | 0.1 |
| Titanium (Ti) | 0.03 | 0.15 |
| Others | Trace | Trace |
Notes:
- AA3104: favored for excellent formability and good corrosion resistance; commonly used in beverage closures.
- AA5052: higher magnesium content provides superior corrosion resistance and strength where required.

| Formability | Excellent | Good to Excellent |
| Corrosion Resistance | Good | Very Good |
Liner Types and Suitability
| Liner Type | Best For | Advantages | Notes |
|---|---|---|---|
| PE/PP Foam | Still wines, basic sealing | Low cost, good compressibility | Not suitable for extended storage with high-acidity wines unless coated |
| Induction Seal (aluminum foil + polymer) | Long-term storage, export | Excellent barrier, tamper-evident | Requires induction sealing equipment |
| PTFE-Coated | Acidic or flavored wines | Chemical resistance, non-reactive | Higher cost |
| Cork Insert / Synthetic Cork | Premium still & sparkling | Traditional appearance, good sealing for cork-like experience | May require special tooling |
Performance Characteristics
Anti-spill effectiveness:
Internal flow diverter reduces edge drips by up to 80% compared with plain caps during pouring tests.
Elastomeric liners further minimize micro-leak paths during tilt and pour.
Leak resistance:
With correct liner and torque, caps can maintain airtight closure for months; induction liners extend shelf-life and tamper-evidence.
Durability:
Coated and anodized finishes withstand common handling and shelf-conditions. Scratches may occur under abrasive conditions.
Compatibility:
Designed to fit standard wine bottle neck finishes; confirm neck outer diameter, thread type (if screw), and sealing surface before ordering.
Applications
- Commercial wine bottling (still wines, fortified wines)
- Small-batch and craft wineries
- Event and wedding bottling (custom printed caps)
- Wine gift bottling and promotional packaging
- Home-bottling and artisanal producers
- Export shipments (when used with induction liners for tamper evidence)

Quality & Compliance
- Food contact compliance: Manufactured to meet applicable food-contact regulations (e.g., FDA 21 CFR where applicable, EU 10/2011 for food packaging — confirm supplier certification).
- Traceability: Batch number and production records available upon request.
- Testing: Dimensional inspections, torque control checks, leak testing, and accelerated corrosion tests performed as part of quality control.
Handling, Storage & Installation Recommendations
- Store in a dry, cool environment away from direct sunlight to preserve coatings and liners.
- Avoid stacking heavy loads that could deform caps.
- Use recommended torque settings during application to ensure consistent seal without damaging liner.
- For induction liners: verify induction sealing parameters (power, dwell time, coil size) to ensure proper adhesion.
- For printed finishes: allow inks and lacquers to cure fully before packaging.
Typical Dimensions Diagram (for reference)
