Diameter

29mm (international standard), suitable for champagne bottle tops (slightly larger than wine bottle tops).

Height

15-20mm (higher than normal caps), to increase pressure resistance.

Material

3105/8011 aluminum alloy (high-strength, corrosion-resistant), thickness about 0.25-0.30mm.

Sealing structure

- Lining material: food grade PE or PVC gasket, resistant to high pressure and acidic environment.

- Edge Roll Seal: Mechanical press fit to ensure air tightness.

Surface treatment

Mostly plain or simply embossed (due to the temporary cover), a few printed with winery code or batch information.

Side

four colors offset printing / embossing / hot foil / silk screen printing

Champagne (traditional method)

Use only during the production phase, replacing the cork after 15-36 months of aging.

Prosecco (in tank)

Partly direct finalization with aluminum cap (elimination of the transfer step).

Asti (primary fermentation)

Aluminum caps are used throughout, due to the short fermentation period (approx. 1 month) and the low pressure (4-5 bar).

Natural sparkling wine

Uncoated aluminum cap + biodegradable gaskets, certified organic.

Non-alcoholic sparkling drinks

Modeled after traditional sparkling wine packaging, with lower pressure requirements in the aluminum cap (2-3 bar).
