Ultrasonic sealing films and fabrics: finds application in the apparel, non-woven, packaging and textiles industries.
The materials may be 100% synthetic, or fibre blends with up to 35% non- thermoplastic fibre content.

Materials which can be processed are polyester, polyethylene, polypropylene, rigid thermoplastics, thermoplastic polyurethane, some vinyls and thermoplastic coated foils and papers.


Ultrasonic welding modes

Three modes of ultrasonic welding film are possible - Continuous, Plunge and Traversing. 


In the continuous mode the material is moved between a stationary ultrasonic horn and a rotating patterned anvil (generally in apparel & textile applications) to seal or cut and seal long lengths. 
E.g.: Lace making machines.


In the plunge mode , the stationary material is in contact with the ultrasonic horn (often with a cutting-edge and welding face) coming down under pressure to cut a specific profile and seal it all along its edge (as in blister packaging, tube sealing, filter pads etc).


In the traversing mode , the ultrasonic horn traverses the weld area, while the material remains stationary. Using appropriate toolings, materials can be bonded together, or slit.

Ultrasonic bonding uses no consumable, and it is energy efficient, compared to thermal bonding.
In ultrasonic slitting, the edges seal simultaneously too; this is beneficial for woven fabrics (prevents unraveling), while at the same time, the selve edge build-up is eliminated. Speed of operation is a significant advantage.
There is little or no downtime.
