What is an Ultrasonic Non-Woven Bag Welding Machine?

The Ultrasonic Non-Woven Bag Welding Machine is equipment that utilizes high-frequency ultrasonic waves to generate internal friction between fabric layers, melting and bonding them together. This process occurs without direct heat or adhesive materials, helping to:

     

  • Preserve the original properties of the material.

    •  

  • Create uniform, aesthetic, and durable weld lines.
  • Ensure the product remains deformation-free.

Machine Operation Process (Based on Illustration Video)

Based on the video content, VietSonic’s automatic ultrasonic non-woven & desiccant bag welding machine operates in the following steps:

     

  1. Roll Feeding: Non-woven fabric is fed into the machine from a roll.

    2.  

  2. Edge Folding: The machine automatically folds the fabric edges to create the bag hem.

    3.  

  3. Ultrasonic Sealing: High-frequency ultrasonic welding heads perform tight, robust sealing.
  4. Cutting & Forming: Bags are cut to the exact preset dimensions.
  5. Finished Product: Completed non-woven bags or desiccant sachets, ready for packaging.

Outstanding Advantages of Ultrasonic Non-Woven Bag Welders

     

  • High Speed: Suitable for mass production, meeting large volume orders.
