How It Compares
| Single-stage inner bag machine | The C19D produces both inner and outer bags in one pass, reducing line complexity and time, but requires more floor space and a higher initial setup |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids heat damage to coffee oils and preserves aroma, but requires an air supply and precise alignment |
| Manual bagging line | The C19D replaces a team of packers and ensures consistent fill weight and seal quality, but requires trained operators and a fixed power and air supply |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the film roll matching the chosen inner or outer bag width and material
- 3Set the inner and outer bag size within the 50-75 mm and 85-120 mm length range
- 4Configure the volumetric cup filler for the target fill weight between 5 and 15 g
- 5Run a test batch of 10 bags and verify fill weight, seal quality, and bag length
- 6Connect to a nitrogen flushing system if shelf life extension is required
