How It Compares
| Manual inner and outer bag sealing | The C19D automates both layers and runs 40 to 60 bags per minute, but requires a fixed floor space of 1200 x 900 mm and trained operator |
|---|---|
| Single-layer heat seal machine | The C19D provides a sealed outer layer for better shelf life and protection, but uses ultrasonic sealing which requires an air supply |
| Flat bag machine with separate sealing | The C19D forms and seals dual bags in one line, reducing footprint and labor, but is specific to drip coffee bag format |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the selected film roll (180 mm for inner, 200 mm for outer) and align the guides
- 3Set the bag size within the 50-75 mm inner and 85-120 mm outer length range
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run 10 test bags and check fill weight, seal integrity, and bag length before batch start
- 6Enable nitrogen flush option if using a nitrogen generator, and connect the hose to the reserved port
