Consumers can appreciate the appearance and the feel of natural cork with our Pearl® microagglomerate. Pearl® stoppers show our continuous commitment toward sustainability and the value chain of the product. The cork shavings, following the punching of natural cork stoppers, are carefully selected, processed and reduced to uniformly-sized particles through a number of mechanical operations. These particles will be subjected to a vaporization and sterilization process through our SARA® system. Only food-grade glues are used.
