Ultrasonic sealing solutions, cold seal for the chocolate industry

With experience over the past 5 years, we are now ready to present our new longitudinal sealing solution based on an innovative ultrasonic system engineered by Cavanna.

Ultrasonic. An innovative sealing application in the flowpack world

Ultrasonic sealing is an alternative to the longitudinal sealing when compared to the traditional way presently in use in the flowpack technology. The ultrasonic transfer is carried out by means of mechanical “micro-pulses” that insure the maximum efficiency.
The exact amount of energy necessary for the sealing action is in fact transferred without damaging the film and or the product.

Our longitudinal ultrasonic sealing system

The longitudinal ultrasonic sealing group is perfectly integrated into the machine.
It is a “cold” group where the sealing energy is mechanical. The control panel of the wrapping machine handles the wrapping parameters (pressure, frequency, etc) in a fully automatic way.
The parameters are customized accordingly to the film type, memorized and recalled when needed.
Several sealing patterns are available to satisfy the aesthetics and sealing requests.
Naturally the sealing quality and speed (up to 100 packs/minute) are in direct accordance with the type of film but generally speaking we can say that this system allows the use of almost all types of flexible films. Test with different materials supplied by our clients are most welcomed in our laboratory for final approval

What are the proven advantages?

• No hot longitudinal sealing elements: this guarantees best quality and safety for your products;
• Waste reduction: because the area is cold, products stopped in the machine are not damaged and do not have to be blown out at the recovery.
• Speed up to 100 linear meters/min.
• Maintenance cost reduction: heaters and collectors are replaced by ultrasonic system
• No noise pollution: the system works well out from the 20.000 Hertz range, which is the human audibility field.
• Particularly suitable for chocolates, frozen food, pharmaceuticals, etc.
