Rotary Ultrasonic Sealing Overview

How Rotary Ultrasonic Sealing Works

Rotary ultrasonic sealing joins packaging materials fast and clean. It uses high-frequency vibrations to make heat only at the seal spot. The system has three main parts. The ultrasonic generator gives power to the system. The transducer turns this power into shaking. The horn, also called a sonotrode, sends these shakes to the packaging. The horn spins while it works. This lets you seal things as they move in the machine. Only the seal area gets hot, not the whole package. This keeps the rest of the material safe. You get a strong seal without hurting the package.

Heat Sealing Overview

How Heat Sealing Works

Heat sealing joins packaging materials using heat and pressure. This method works best with thermoplastic materials. You put the package between heated metal bars. The bars press together and warm up the material. The heat melts a thin layer inside the package. Pressure holds the layers together for a short time. When the material cools, it forms a strong bond. You get a seal that keeps out air, moisture, and dirt.

• Heat sealing uses heat and pressure to join thermoplastic materials.

• Metal seal bars are heated to a set temperature.

• Pressure is applied for a short time, then the seal cools while still pressed.

• This makes a strong, airtight closure.
