The MASZONE® technology enables the sterilisation and elimination of microorganisms. It is used in the production process of all cork stoppers – natural and technical – produced and marketed by MASILVA.

All our cork stoppers are subject to a washing and sterilisation process, which uses not only ozone, but also the most powerful peroxone, a combination of ozone and hydrogen peroxide, to disinfect and clean cork stoppers.

This solution eliminates microorganisms and their spores, while oxidising organic impurities and compounds, such as phenols and anisoles, which can be precursors of compounds with undesired odours.

The MASZONE® system also improves the visual appearance of the cork stopper.
