Key Benefits
- Forms and seals inner and outer bags simultaneously to double packing speed compared to sequential machines
- Ultrasonic sealing avoids heat damage to coffee aroma and maintains a narrow, clean seal edge
- Volumetric cup filling delivers consistent 5 to 15 g per bag with minimal giveaway
- Stepper motor controls outer bag length positioning for accurate, stable bag sizing
- PLC control with human machine interface allows simple setup and monitoring by one operator
- Supports nitrogen flushing via reserved connector to extend coffee shelf life
Application Scenarios
- Small coffee roasters in China packaging single-origin beans for direct-to-consumer e-commerce

How It Compares
| Manual inner and outer bagging | The C19D replaces a manual team and ensures consistent fill weight and seal quality, but requires a fixed power and air connection |
|---|---|
| Single bag sealing machine | The C19D produces both inner and outer bags at once, increasing throughput, but requires more setup time for dual film rolls |
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids heat damage to coffee aroma and reduces film waste, but requires an air supply for the sealing head |

- 2Load the inner and outer film rolls matching your chosen bag size and material
- 3Set the volumetric cup to the desired fill weight between 5 and 15 g
- 4Adjust the stepper motor for outer bag length within the 85 to 120 mm range
- 5Run a test batch of 10 bags and verify fill weight, seal integrity, and bag size
- 6Install optional devices like date printer or nitrogen connector as needed
