How It Compares
| Manual inner and outer bag assembly | The C19H-2 automates both layers, increasing output and consistency, but requires a fixed footprint of 1200 x 900 mm and trained operator |
|---|---|
| Heat sealed drip bag machine | Ultrasonic sealing avoids heat damage to coffee and glue residue, but requires an air supply for the sealing head |
| Single-layer coffee bag machine | The C19H-2 adds a sealed outer layer for protection, but uses more film and requires more setup time |
