Let’s first understand the specific location of aluminum used in wine capsules

What are wine capsules used for? Wine capsules are the bottle seals, which are located on the top of the bottle mouth, so they are called “wine caps”. Its main function has three points, preventing insect damage, anti-counterfeiting, and carrying wine information.

Which aluminum materials are used for wine capsules

There are many kinds of materials for the manufacture of wine caps. Aluminum wine capsules generally use 8011 aluminum foil and 3105 aluminum alloy.

8011 aluminum foil is mainly added with Fe, Si and other elements. It is a commonly used packaging material with excellent moisture resistance, light shading and high barrier capacity. Non-toxic and tasteless, safe and hygienic.

8011 aluminum foil is widely used in the field of bottle cap materials: it can be used for liquor bottle caps, red wine bottle caps, wine caps, cosmetic bottle caps, milk powder caps, medicine caps, beverage caps, yogurt caps, easy-open caps, etc.

3105 aluminum alloy belongs to aluminum-manganese alloys. This series of products has good formability, high corrosion resistance, excellent weldability, and high elongation, which meets the requirements for material strength and elongation in the production process of wine caps. No cracks or creases occur during deep drawing.

Advantages of aluminum wine capsules

Stable sealing performance

The inner pad of the aluminum bottle cap adopts a special sealing material, and its low permeability and zero permeability characteristics effectively prevent the oxidation of the wine in the bottle, so that the wine maintains freshness and retains fruity aroma. No matter how long it is stored, no chemicals will be produced.

Health and Environmental Protection

The resources of bauxite are relatively abundant. After the aluminum bottle cap is used, it can be recycled without causing environmental pollution. Mingtai 8011 aluminum foil brush water grade A, has excellent moisture-proof performance, shading and high barrier ability, non-toxic and tasteless, safe and hygienic.

easy to use

The aluminum bottle cap is easy to open without special tools; the used cork cannot be recycled, causing environmental pollution.

Short production cycle

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