Glossary term
Ultrasonic welded seam
A seam produced by high-frequency vibration that locally melts and fuses thermoplastic fabrics along the join.
Definition
Ultrasonic welding delivers a quick, clean, thread-free seam on thermoplastic fabrics — useful in disposable medical garments and some technical apparel.
Ultrasonic bonding is a surface-fusion technique; durability and barrier integrity depend strongly on fabric chemistry and machine control.
Why it matters to DSEAMS
Cohesive CIBS is compatible with ultrasonic welded seams as one of multiple supported seam types. DSEAMS generally delivers superior barrier integrity via inline lamination rather than surface welding.
