Pilfer proof aluminium wine screw caps are a revolutionary product in modern wine packaging. Made from aluminum alloy using precision stamping, roller printing and padding processes, their core functions are sealing and preservation, temper evident and brand display. Pilfer proof aluminium screw caps are widely used in packaging for high-end beverages such as wine, spirits and olive oil. This kind of bottle cap effectively isolates oxygen through zero-permeability sealing technology, preventing oxidation and spoilage of the wine. It also features an anti-theft interlocking design; if opened, the interlocking points break, leaving irreversible marks and ensuring product security.

Specifications of pilfer proof aluminium wine screw cap:

Alloy material:

Mainstream use is 8011-H14 or 3105-H14 aluminum alloy. The former is the industry's preferred choice due to its high strength and good ductility. The alloy must meet the following requirements: surface flatness ≤0.1mm, free from roller marks, scratches, and stains to ensure printability.

Thickness range:

Standard thickness is 0.20-0.23mm, with tolerance controlled within ±0.01mm. For example, a 30×60mm bottle cap typically has a wall thickness of 0.23mm to balance sealing performance and cost.

Common sizes:

30×35mm: Suitable for small-capacity wine bottles (e.g., 187ml single-glass bottles) or spirits bottles.

30×60mm: Standard size for mainstream international wine bottles (750ml), compatible with Bordeaux bottles with a neck diameter of 28-30mm.

Custom: Supports non-standard sizes from 25×43mm to 31.4×60mm to meet special bottle shape requirements.

Inner liner types:

Saran/tin gasket: PVDC coating + tin layer, zero permeability, suitable for wines aged 10 years and older.

Saranex gasket: Double-layer PVDC polymer, low permeability, suitable for wines consumed within 10 years.

Foamed PE gasket: High-elasticity material, compensates for bottle neck errors, and improves sealing.

Surface finishes:

Printing: Supports multi-color side printing, top flexographic printing, silkscreen hot stamping, embossed hot stamping, etc., enabling gradient colors, 3D embossing, and other effects.

Coating treatment: The outer surface coating has a hardness ≥4H and is resistant to pasteurization (no discoloration or peeling at 80℃/10min). The inner surface meets food-grade hygiene standards.

Anti-counterfeiting design: Laser engraving, QR code traceability, and thermochromic ink anti-counterfeiting technologies can be integrated into the bottle cap.

Customization support:

We provide a full-process service from structural design to brand element customization, including logo hot stamping, exclusive pattern development, and anti-counterfeiting label embedding. Minimum order quantity is 10,000 pieces.

Core features and advantages of pilfer proof aluminium wine screw cap:

1. Sealing and Preservation Performance:

Zero oxygen permeability: Saran/tin gasket oxygen permeability ≤0.01cc/(m²·24h·atm), completely isolating oxygen and preventing wine oxidation and spoilage.

Moisture-proof and antibacterial: Water permeability ≤0.05g/(m²·24h), avoiding microbial contamination and extending shelf life to over 10 years.

Elastic compensation: The foamed PE gasket can adapt to bottle mouth tolerances of ±0.3mm, ensuring consistent sealing.

2. Temper evident and anti-counterfeiting features:

Eight-point breakage indicator: Upon opening, eight points break, creating irreversible marks and preventing refilling.

Integrated anti-counterfeiting technology: Supports laser anti-counterfeiting codes, thermochromic inks, RFID chips, etc., constructing a multi-layered anti-counterfeiting system.

3. Environmental protection and sustainability:

100% recyclable: Aluminum alloy recycling consumes only 5% of the energy of primary aluminum, reducing carbon emissions by 95%, complying with EU EPR regulations.

Lightweight design: Compared to traditional corks, aluminum wine bottle caps are 60% lighter, reducing carbon emissions during transportation.

4. Optimized user experience:

One-button opening: No corkscrew required; simply rotate three times to open, suitable for outdoor and aviation scenarios.

Resealable: Can be resealed after drinking, maintaining wine freshness for over 72 hours.

Anti-contamination design: Eliminates the risk of TCA contamination from corks, avoiding off-flavors such as "wet cardboard."

5. Brand value enhancement:

Premium texture: Metallic luster and precision craftsmanship give the product a luxurious feel, increasing consumer willingness to pay.

Personalized customization: Differentiated packaging is created through color, patterns, and anti-counterfeiting technology, enhancing brand recognition.

Market adaptability: Adopted by 80% of wineries in countries such as Australia and New Zealand, aligning with international wine packaging trends.

Application cases of pilfer proof aluminium wine screw cap:

Penfolds 1996 Vintage:

Sealed with Saran/tin gasket aluminum screw caps, after 10 years of aging, it retained 92% of its fruit aromas, receiving high praise from the expert panel of *Wine* magazine.

New Zealand Cloud Bay Sauvignon Blanc:

Using Saranex gasket aluminum caps, the aroma intensity after opening is 30% higher than with cork sealing, increasing repurchase rate by 15%.
