Overview

There is nothing faster than Sonitek's Clamshell & Blister Pack Sealing! Ultrasonics eliminates adhesives, glues, staples, clips, RF & thermal. No other sealing process is faster or as cost-effective as ultrasonics!

What is Ultrasonic Clamshell Sealing?

Ultrasonic clamshell sealing is a packaging method that uses high-frequency vibrations to create a strong bond between plastic materials. The vibrations cause the plastic molecules to soften and bond together when held in place by a sealing anvil, creating a tamper-proof seal. This process is highly efficient, providing a secure and durable seal that meets all major retailers' requirements for packaging integrity.
