Title: Understanding the Ultrasonic Process of Non-Woven Bags
Non-woven bags often use ultrasonic technology to bond materials. Unlike sewing, ultrasonic bonding uses high-frequency vibrations to melt and join fabrics. This process is fast and clean, leaving no thread or needle marks.
Ultrasonic bonding makes bags look neat and smooth. It is ideal for lightweight bags used in shopping or promotions. The strength of the bond depends on the fabric type, thickness, and machine settings.
However, ultrasonic technology requires precise control. If done incorrectly, the bag can tear easily. This method is widely adopted in modern bag manufacturing because it is eco-friendly and efficient.
