Key Benefits
- Forms and seals inner and outer bags simultaneously, reducing line footprint and operator handling
- Ultrasonic sealing creates a narrow, strong seam without heat or adhesive, preserving coffee aroma
- Volumetric cup filling delivers consistent 5 to 15 g per bag with no overfill or giveaway
- PLC control with human machine interface allows quick setup and easy operation
- SUS304 stainless steel parts in food contact zones meet food safety standards
- Stepper motor controls outer bag length positioning for accurate, repeatable bag sizing
Application Scenarios
- Coffee roasters packaging Mandheling and other specialty beans in inner and outer bags for retail or wholesale
- Contract packers running multiple coffee brands with short batch sizes and quick changeover
- Roasters upgrading from manual bagging to a fully automatic line with nitrogen flushing capability
- Packaging facilities needing a compact machine that handles both inner and outer bag sealing in one unit
Who It Is For

How It Compares
| Separate inner and outer bag machines | The C19D combines both steps into one line, reducing floor space and handling, but requires a single machine with dual film handling |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film melting and preserves aroma, but requires an air supply and is not suitable for all film types |
| Manual bagging with hand sealing | The C19D replaces a manual team and holds 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 inner and outer film rolls matching the 180 mm and 200 mm widths
- 3Set inner bag size to 50-75 mm length and 50-90 mm width, outer bag to 85-120 mm length and 75-100 mm width
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run ten sample bags and check fill weight, seal quality, and bag length before batch start
- 6Use the reserved connector to link with a nitrogen flushing system if required
