Basics Ultrasonic sealing

Ultrasonic sealing is particularly well suited for:

  • Thermoplastic films (pouches and bags) Tubes, trays, and cups
  • Tubes, trays, and cups
  • Cardboard packaging with thermoplastic coating
  • Valves and vents on films / filter materials
  • Screw caps on coated cardboard packaging / films

Generation of heat at the inside of the seal during ultrasonic sealing
