How It Compares
| Single inner bag machine | The C19II-2 adds an outer envelope in one line, reducing manual handling and improving shelf stability, but requires more floor space and higher power |
|---|---|
| Manual envelope application | The C19II-2 automates outer envelope sealing and positioning, eliminating human error and increasing speed, but requires initial setup and training |
| Basic heat seal machine without PID control | The C19II-2 uses PID temperature control for consistent sealing, reducing waste from over or under-sealing, but requires more complex electronics |
Use Guide
- 1Connect a clean dry single phase 220V 50Hz power supply with 3.7 kW capacity
- 2Load the chosen film roll (180 mm for inner, 200 mm for outer) and align it to the guide rollers
- 3Set inner and outer bag size parameters on the touch screen based on your target dimensions
- 4Enter fill weight between 5 and 15 g and calibrate the measuring cup with your coffee
- 5Run 10 test bags and check seal quality, bag length, and fill consistency
- 6If using nitrogen, connect the machine to a nitrogen generator via the reserved connector
