Screw Cap Red Wines: Aluminum V Cork

The screw cap of red wines is usually made up of corks. However, with the development of society and technological progress, the corks have been gradually replaced by aluminum cap material. Now the red wine cap material are mostly made of 8011 aluminum foil.

What Is 8011 Aluminum Foil

With Al-Fe-Si element, 8011 aluminum foil is of excellent moisture resistance, light shielding, high barrier ability, strong mechanical properties, high blast resistance, strong puncture resistance, clean surface and no pinholes. In addition, it is non-toxic, tasteless, safe and hygienic.

Sealing Performance

The inner cushion of the aluminum ropp caps is of a special sealing material. Its low permeability prevent the oxidation of the the red wine, so the freshness and fruity aroma of the red wine can be well kept. No any chemical will be produced even for long-term storage.

The permeability of the cork is too large or not stable. In addition, there are errors in different bottles, and the elasticity of the cork stoppers result in different sealing degree.

Environmental Protection

Aluminum ore resources are relatively abundant, And the aluminum caps can be recycled without causing environmental pollution. Haomei 8011 aluminum foil is of Class A, which has excellent moisture resistance light shielding and extremely high barrier ability.

There is a shortage of raw materials for cork stoppers. After use, the cork stoppers cannot be recycled,causing a waste of resources.

User Experience

Aluminum caps is easy to open without special tools while the cork needs a special tool to open. And if you don’t drink it once, you need to buy another cap closure to seal the wine bottle.

Production Period

The production period of aluminum caps is short, which can realize large-scale mechanized production and large output.

The cork stoppers has a long production cycle, which can’t realize automatic production. Therefore, they are of small production batches and expensive production cost.
