INTRODUCING ... OUR NEWEST PRODUCT

With determination to continuously evolve and meet market trends and demands, MA Silva's latest technology evolves our sterilization of cork granules. 

Consumers can now enjoy the look and feel of natural cork with our NEO® micro agglomerate cork. NEO® cork stoppers carry our ongoing commitment to sustainability and the product value chain. 

The cork granules are carefully selected and processed with a series of mechanical operations to reduce the material to even-sized particles. Once the granulate are sized, they are treated with fluidized bed technology. 

Afterwards, the granules undergo steaming and sterilization process using our NEOTECH® system. Only food-grade binding agents are used.
