At present, most of the packaging for vodka, wine, medicinal wine, etc. on the market is still glass bottles, and about 50% of the wine bottle caps are anti-theft caps made of aluminum closure sheets. Aluminum screw caps have the ability to keep the contents of the product airtight, and also have anti-theft opening and safety functions. Therefore, they are highly recommended in wine bottle caps, cosmetic bottle caps, beverage bottle caps, and medicinal bottle caps.

MC Aluminum is a manufacturer of aluminum alloy raw materials for anti-theft wine lids. The company produces 3105 aluminum sheets and 8011 aluminum foils with a thickness of 0.15-0.3mm, in states of H12, H14, H16, etc.

One of the processes for using aluminum sheets for wine bottle sealing caps is heat treatment, which is called finished product heat treatment. This treatment includes annealing, solution treatment, quenching, natural aging and artificial aging. MC Aluminum also has graded aging and deformation heat treatment processes. Artificial aging treatment can improve the mechanical properties of aluminum products for wine bottle caps and improve their stress corrosion resistance and fracture toughness.

Advantages of aluminum sheets for wine bottle screw caps:

1. It has strong barrier properties, which can avoid contamination of products by microorganisms, moisture or gas, extend the shelf life, and ensure flavor and taste.

2. Non-toxic and odorless, environmentally friendly and recyclable, more environmentally friendly.

3. Easy to open and close, with anti-theft function.

4. It has good formability and can be printed, embossed or milled in color.

5. High temperature resistance, corrosion resistance, moisture-proof, light weight and good sealing.
