ULTRASONIC WELDING IN POUCH MANUFACTURE

摘要

Pouch containers that are in the process of being filled can advantageously be sealed using ultrasonic welding techniques. Ultrasonic welding produces effective seals in areas which have become coated with the substance flowed into the pouch. Further, the pouch containers which are sealed by ultrasonic welding can be severed one from the other using the ultrasonic sealing units to sever the film after sealing the film This can be done by the energy director on the ultrasonic horn having sidewalls of a given angle and by increasing the pressure of the ultrasonic horn against the anvil.
