Sustainability, process reliability, and efficiency—these are the three major requirements that modern packaging technology must meet simultaneously. Ultrasonic welding technology demonstrates how to achieve this goal.

The packaging industry is undergoing a period of transformation. Laws and regulations, corporate sustainability goals, and consumers' increasing environmental awareness are prompting the industry to rethink materials and processes.

Single-material and paper-based packaging are considered potential alternatives to traditional plastic composites—but their processing poses technical challenges to conventional joining methods such as heat sealing.
