How ultrasonic sealing works


In ultrasonic technology, the friction process generates localized heat, due to the molecular movement of the two plastic films in the point of contact with the vibrating sonotrode. The molecules of the two films do not only change their position, but they bind to each other, thus forming the weld.

Following this principle, wet, damp or dusty surfaces can be hermetically sealed, achieving full strength for maximum production speeds.

Ultrasonic sealing brings further advantages, particularly for handling frozen food and dusty products that may contaminate the seal area and reduce seal quality.


Many advantages with ultrasonic sealing


Using ultrasound rather than traditional heat sealing is extremely advantageous, saving packaging materials, and eliminates build-up of film residue on the sealing tools for faster cleaning and considerably reduced downtime.


Sonic Italia is an expert in ultrasonic technology for numerous industries. We offer a wide range of professional, state-of-the-art machinery focusing on top quality materials, easy maintenance and high standards in uniformity and hygiene. Please contact us for any further information
