What Is an Ultrasonic Bag?
An ultrasonic bag is made by bonding fabric together using high-frequency ultrasonic vibrations—no sewing, no thread. We use ultrasonic welding technology to fuse the materials directly, which makes the seams clean, strong, and uniform. These bags are especially great when you want a clean finish without needle holes or stitching lines.
At our factory, we typically produce ultrasonic bags using non-woven fabric, PP, PET, or other eco-friendly materials. The whole process is quick, precise, and consistent, which helps reduce labor costs while improving efficiency and appearance.
If you need a bag for promotions, shopping, or lightweight packaging that looks neat and lasts long, ultrasonic bags are a smart choice. Plus, we can fully customize the size, handle type, printing, and color to match your branding.
What are the advantages of ultrasonic non-woven bags over stitched ones?
Ultrasonic bags offer cleaner edges, stronger bonding, and no thread breakage. They are more durable, hygienic, and better suited for high-volume automated production.
Can I customize the size and design?
Yes, all ultrasonic bags can be fully customized in terms of size, color, handle type, thickness, and printed logo.
Are these bags eco-friendly?
Yes. Our bags are made from recyclable polypropylene fabric, and we also offer biodegradable and laminated options upon request.
What printing options are available?
We support screen printing, heat transfer, gravure printing (laminated bags), and ultrasonic-embossed logos depending on the bag type.
What is your MOQ (Minimum Order Quantity)?
Our MOQ generally starts from 5,000 pcs per design, but we offer flexibility depending on the customization and material type.

What is your production lead time?
