Customization Options
- Choice of inner and outer bag size within the 50-75 mm and 85-120 mm length range
- Selection of film type: PLA/Paper/Plastic, Plastic/Aluminum/Plastic, Paper/Aluminum/Plastic, or filter paper

How It Compares
| Separate inner and outer bag machines | The C19D combines both steps into one line, reducing floor space and labor, but requires a single film roll for both layers |
|---|---|
| Heat seal coffee bag machine | Ultrasonic sealing avoids high heat that can degrade coffee aroma, but requires an air supply for the sealing head |
| Manual bagging with hand filling | The C19D replaces a manual team and ensures consistent fill weight, but needs a fixed 1200 x 900 mm footprint and trained operator |
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 film path
- 3Set bag length and width using the PLC interface to match your inner and outer bag size
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run ten test bags and check fill weight, seal quality, and nitrogen flush function if equipped
- 6Clean the volumetric cup and sealing heads between different coffee types to prevent flavor carry-over
