How It Compares
| Single-layer coffee bag machine | The C19H provides dual-layer protection with an inner bag for freshness and an outer bag for branding, but requires more film and setup time |
|---|---|
| Heat sealed coffee bag machine | Ultrasonic sealing avoids film scorching and maintains a narrow seal, but requires an air supply for the sealing head |
| Manual dual-layer bagging | The C19H automates both inner and outer bag formation, improving speed and consistency, but requires a fixed floor space of 1200 x 900 mm |
Use Guide

- 2Load the selected film roll (180 mm for inner, 200 mm for outer) and align the guides
- 3Set the inner and outer bag size within the 50-75 mm and 85-120 mm 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 integrity, and outer bag positioning
- 6Install optional devices like date printer or easy tear feature if needed
