Watttron solution optimizes thermoformed packaging with mono-materials

Packaging manufacturers are increasingly using mono-materials, as they are easier to recycle than packaging made from multiple materials. However, it is a challenge to process mono-materials in a limited processing window and to reliably bond them together. The German Dresden-based start-up Watttron has developed cera2seal, a digital heating system that enables consistent sealing in packaging machines through the targeted use of heat. The system also saves energy in production.

This week, Watttron presented its digital heat seal system for packaging to a specialist audience and journalists at its in-house factory event in Freital on the occasion of the Dresden Packaging Conference, December 5-6. The cera2seal system was presented in operation on several packaging machines including Grunwald and Velteko, demonstrating that the precise sealing of yogurt lids and stand-up pouches is possible with the watttron technology.
