How It Compares
| Manual inner and outer bagging | The C19D replaces hand labor and ensures consistent fill weight and seal quality, but requires a fixed floor space and trained operator |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids scorching and adhesive residue, but requires an air supply for the sealing head |
| Single bag packing machine | The C19D produces inner and outer bags in one cycle, reducing time per unit, but requires more setup for dual film handling |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load inner and outer film rolls matching 180 mm and 200 mm width specifications
- 3Set inner and outer bag sizes within the 50-75 mm and 85-120 mm length range
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run ten sample bags and verify fill weight, seal quality, and nitrogen flushing (if equipped)
- 6Clean the filling cup and sealing heads between different coffee types to prevent aroma carry-over
