Application Of Metal Closure in Red Wine

Tightness enhancement and oxidation resistance
The metal screw cap achieves zero permeability through a special material (e.g. a polymer seal) on the inner line, which significantly reduces oxygen permeation and prevents the degradation of red wine due to oxidation.
In contrast to cork stoppers, metal lids completely insulate from "cork contamination" (TCA contamination) and reduce the risk of spoilage.

Convenience and environmental friendliness
It can be opened without a corkscrew and is resealable, making it suitable for ready-to-drink red wines (e.g. dry white and young red wines).
Reduce the demand for cork oak trees and reduce deforestation pressures, in line with the Sustainable Development Goals.

Anti-counterfeiting and anti-insect function
Metal closures (e.g. tin foil, aluminium sleeves) prevent pests from eating on the cork and improve packaging security (e.g. brand logo).
