Ultrasonic sealing is particularly well suited for:
- Thermoplastic films (pouches and bags) Tubes, trays, and cups
- Tubes, trays, and cups
- Cardboard packaging with thermoplastic coating
- Valves and vents on films / filter materials
- Screw caps on coated cardboard packaging / films
Joint design
Focusing by means of contouring of the anvil structure
To initialize the melt formation, it is required for the introduced vibration energy to be focused. With film and other flexible packaging materials, this is achieved through appropriate tool design. More about energy focusing
