NEO® MICRO AGLOMERATED CORK STOPPERS

With micro-agglomerated NEO® stoppers, consumers can appreciate the look and feel of natural cork, which demonstrates our ongoing commitment to the quality and sustainability of the cork stopper value chain.

After punching the natural cork stoppers, cork shavings are carefully selected and processed.

There are two types of micro cork stoppers: Neo Prestige® and Neo Plus®.

Through a series of mechanical operations, the material is reduced to uniformly-sized particles. These particles are carefully treated, through moulding – a process for producing agglomerated bodies – and cutting edge MASILVA technologies.
