What is ultrasonic package sealing?

Ultrasonic package sealing occurs when high frequency (ultrasonic) mechanical energy is transferred into two or more layers of thermoplastic materials. A strong, reliable molecular bond is formed between the layers. Nearly all packaging materials and laminates, with a thermoplastic sealing layer or coating, are suitable for the ultrasonic sealing (welding) process. Both hermetic and peelable seals can be achieved with ultrasonic sealing systems. Altrasonic has developed an advanced ultrasonic sealing solution. Ultrasonic energy generates localized frictional heat sealing the packaging materials.

3. Form-fill seal bags - vertical and horizontal configurations

4. Cartons

5. Pour spouts on gable top cartons

6. Blister packs

7. Clam shell packs

8. Cups/trays

9. Tube seal

10. Fitments on pouches

11. De-foaming of liquids
