Improving Rotogravure Press Operations: A Case Study in Ultrasonic Curing of Water-Based Varnishes (OPV) on Food Packaging Materials

Presented by Gene Plavnik, "Heat Technologies, Inc."

Heat Technologies, Inc (HTI), the provider of the Spectra Ultra HEÔ  acoustic ultrasonic heat and mass transfer technology for the crosscut of industries, will discuss results of the operational advantages of ultrasonic curing of the food packaging materials on rotogravure presses and coating lines. This presentation by Heat Technologies, Inc. (HTI) will showcase the results of deploying its Spectra HE™ ultrasonic technology on wide web rotogravure press and corresponding coating line for printing and curing processes respectively. We will focus on practical experience and quantifiable improvements, including: - **Significant Energy Reduction:** Lowering energy costs by replacing or supplementing conventional hot air dryers. - **Increased Production Speed:** Eliminating drying bottlenecks to better utilize the full mechanical speed of the press. - **Reduced Labor and Waste:** Streamlining operations and improving final product quality. Beyond a brief overview of the acoustic heat and mass transfer principles, the session will provide a technical roadmap for implementation, supported by photo and video evidence. Attendees will gain a clear understanding of how ultrasonic curing provides a competitive advantage in the production of modern, eco-friendly food packaging.
