Ultrasonic bonding

There is a way to bond nonwovens and films without adhesive. The ultrasonic technology works by running the system through a small, controllable gap between the weld horn and the anvil drum. The non-contact non-wear ultrasonic bonding technology, in combination with Promea's laminating calender, ensures consistent bonding at high speeds of 1000+ ft/min., and reduces wear to an absolute minimum.

The elimination of adhesive results in a cost saving:

  • no cleaning or maintenance from clogged nozzles

  • no more lost production time due to warm-up time of the system

  • lower energy consumption

  • reduced spare parts cost

  • no waste at start-up and machine stop

Another advantage of this new technology is that materials with different melt temperatures can be joined.
