Project Experience

Biobased wine corks

The company Vinventions manufactures bottle caps and corks for the wine industry. Plant-based raw materials based on sugar cane are used as raw material for direct extrusion. Leistritz has been working together with Vinventions since 1997. Together, 15 plants have already been started up.

Sustainability and energy efficiency

The project combines sustainability, energy efficiency, and a low carbon footprint with outstanding product characteristics for high-quality wines.

Leistritz contributed with its experience in compounding and extruder design to integrate the fluctuating quality of plant-based raw materials into a stable process that reliably delivers consistently high product quality. For this purpose, intensive use was made of the Leistritz technical center, which gave the customer a high degree of flexibility without interfering with ongoing production.
