Ultrasonic Non-Woven Bag Sewing Machine

VietSonic Ultrasonic Sewing Machine – Optimizing Production…

1. Introduction to Ultrasonic Sewing – Future Technology

The VietSonic ultrasonic sewing machine utilizes high-frequency waves (approx. 20 kHz) to generate frictional heat, melting and bonding layers of non-woven fabrics, technical textiles, woven PP, and various other soft materials – eliminating the need for traditional needle and thread.

Key Benefits:

Sharp, strong, and water-resistant welds.
Completely eliminates lint and excess thread issues – especially critical for medical and cleanroom products.
Increases production speed up to 4 times compared to conventional sewing, saving labor and cleaning costs.

2. Applications in Non-Woven Fabric & Dust Cover Production

With the capability to seal edges and “cut & seal” simultaneously with diverse patterns, this machine is the ideal choice for producing:

High-quality PP non-woven bags, drawstring bags, and shopping bags.
Protective cover bags, caps, raincoats, curtains, and medical/cleanroom products.

The ultrasonic sewing machine also creates sophisticated embossed patterns on the bag surface, enhancing aesthetic value and branding – something traditional sewing struggles to achieve.
