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
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
Longitudinal sealing ensures protection of the product through reduced drop heights and saves packaging material due to minimum film overlap.
Hermetic seals, even with contamination in the sealing area. It is possible to produce completely air-free pouches with liquids.
The ultrasonic sealing technology guarantees absolutely tight seals both for hot-fill and for aseptic or retort pouches.
The vibration of the ultrasonic tools allows for obtaining reliable seal quality despite a dusty filling environment.
