Innovation by Vetropack: Echovai technology

Tempered glass is not a new idea and has been used, for example, in car windows for a long time. In the case of glass bottles, however, the process had clearly reached its limits. The reason: during the tempering process, the bottle blanks must first be strongly heated and then shock-cooled. This is the only way to create the necessary internal tension and stability in the material. Flat glass can be treated this way without issues. With glass bottles, however, wall thickness distribution varies – which can cause cracks during tempering. This made profitable production of tempered glass containers impossible. 

For almost ten years, Vetropack's research and development team has been working on a production process for tempered lightweight glass bottles. With Echovai technology, it is now possible for the first time to thermally harden glass bottles. To date, Vetropack is the only glass packaging manufacturer worldwide to offer this solution.

Unique production process ensures particularly high stability

Echovai technology places particularly high demands on both the quality of the bottles themselves, as well as the production process and the equipment. "We adjust the entire tempering process very precisely to the individual container and its shape. It's a very sophisticated, technologically demanding process that can't be implemented on just any production line,” says Daniel Egger.

The stable lightweight glass containers are currently produced exclusively at the plant in Pöchlarn, Austria. Other Vetropack plants are set to follow and will be prepared for Echovai production – the prerequisite for being able to meet the demand for Echovai bottles throughout Europe. "We expect this demand to grow very quickly," says Daniel Egger. "Especially since the performance of Echovai with the first users has yielded outstanding results."
