How does ultrasonic welding for valve bags work?
The valve bag has been designed to pack powder products quickly and efficiently. The ultrasonic welding of valve bags guarantees airtight welding seam at high speeds, even in the presence of residual powders on the valve. Ultrasonic welding takes place because one of the intermediate layers of the bag is made of polyethylene.
Sonic supplies ultrasonic systems to companies in the field, which manufacture this type of systems and makes available its expertise and its welding equipment to OEMs.
