Sealing and pressing is to melt and bond two or more layers of materials together by using heated roller or ultrasonic wave. In automatic production line, all materials are continuously running. The basic principle of existing sealing device is to use sealing roller rotation sealing or use ultrasonic wave sealing head and sealing roller to heat sealing by high-frequency vibration wave.

For roller sealing, due to short contact time, high sealing pressure and temperature are required, which can easily cause damage to sealing part and harden after cooling, affecting product quality, and there is a risk of scalding at high temperature. Due to the characteristics of ultrasonic wave sealing, the ultrasonic wave generator is fixed, while the material is continuously running. There is a large speed difference between the ultrasonic wave sealing head and the material during sealing, which can easily wear the material and the ultrasonic wave sealing head.
