How Does Ultrasonic Hermetic Sealing Work?

The friction process generates localized heat, caused by the molecular movement of two different films in vibrating sonotrode’s contact point. Even though molecules do not change their position, they bind together and remain welded.

These Vertical Form Fill Sealing (VFFS) processes allow for wet, damp or dusty surfaces to get hermetically sealed, thus adding outstanding speed to the production process. Hermetic sealing is widely employed in the food and construction supply industries, specially for frozen goods, ready-to-eat salads, grated cheeses, sand and cement bags.

This type of hermetic sealing using ultrasonic offers several benefits when working with cold or friable items that could contaminate the welding area and severely reduce the quality of its hermetic holding with a traditional method.

Employing ultrasonic hermetic sealing instead of the standard thermosealing procedure brings a series of advantages. Preserving packaging materials and avoiding to get film residues in the soldering tool. This allows for a quicker cleaning and a considerable reduction of downtime intervals.
