- Inability to switch between long-line and short-line formats without downtime
- Low pass rate from inconsistent bonding leads to waste and rework
Technical Features
- Ultrasonic bonding with three sealing devices for consistent label adhesion
- Trigger-type ultrasonic system with high stability and low failure rate
- PLC control with human machine interface for full process monitoring

How It Compares
| Manual label attachment | The C25 replaces hand placement with consistent, high-speed bonding, but requires a fixed footprint and trained operator |
|---|---|
| Glue-based labeling machine | Ultrasonic bonding avoids adhesive residue and film damage, but requires an air supply and higher initial setup |
| Heat sealing machine | Ultrasonic sealing avoids scorching thin films and provides cleaner edges, but needs precise air pressure control |
Use Guide
- 1Connect a clean dry air supply at 0.6 MPa and a single phase 220V 50Hz power outlet
- 2Load the film roll with width matching your selected 120, 140, 160 or 180 mm setting
- 3Install the label roll with 76 mm core and ensure outer diameter does not exceed 400 mm
- 4Set label length between 110 and 130 mm and verify alignment on the first few marks
- 5Run a test batch of 20 marks and check label adhesion and placement before full production
- 6Clean the ultrasonic heads and label feed path between different film types to prevent contamination
