Ultrasonic Welding Packaging
Advantages
Valve bags are used to transport powders, grains and volatile materials in general.
Valve bag filling machines may feature a single ultrasonic sealing system, or several systems arranged in line or in a circle, based on each manufacturer’s design.
Sonic Italia developed a specific 20 khz sealing set for this kind of plants.
- Product particles removed from the sealing area
- Increased production line speed
- Shorter sealing and cooling times
- Quality sealing even in areas contaminated by residues
- Immediate operation at switch-on without the need for pre-heating
- Sonotrodes do not require heat and remain clean for longer
- Environmentally-friendly
Ultrasonic technology
In the packaging field, ultrasonic technology greatly exceeds the performance of traditional heat sealing, eliminating any contamination risk, generating less waste and rejects. This technology helps to contain the materials’ size, as it does not require any distance between product and seal, and, since the ultrasonic vibration system does not need to be heated, saving large quantities of raw materials.
