Key Benefits
- Produces inner and outer bags simultaneously, reducing cycle time compared to sequential packing
- Ultrasonic sealing ensures a clean, strong seal without heat or adhesive, preserving coffee aroma
- Stepper motor controls outer bag length positioning for accurate and repeatable bag sizing
- Volumetric cup filling delivers consistent fill weight across 5 to 15 g per bag
- SUS304 stainless steel parts in food contact zones meet food safety standards
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation
Application Scenarios
- Robusta coffee roasters packaging single-origin or blended beans for retail or food service
- Contract packers running multiple coffee brands with short batch sizes and quick changeover
- Coffee producers adding a hanging ear bag format to their product line for retail display
- Brands requiring nitrogen flushing to extend shelf life in high-temperature or long-haul markets
Who It Is For
- Coffee roasters transitioning from manual or semi-automatic packing to full automation
- Contract packers handling multiple coffee brands with different bag sizes and fill weights

How It Compares
| Single-layer coffee bag machine | The C19D produces dual-layer inner and outer bags with a hanging ear, while single-layer machines cannot provide the same protection or retail display benefit |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film damage and preserves aroma, but requires an air supply and more precise setup |
| Manual bagging line | The C19D replaces a team of packers and holds fill weight to 5 to 15 g, but requires a fixed floor space of 1200 x 900 mm and trained operator |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz outlet with 3.7 kW capacity
- 2Load the film roll matched to your chosen inner and outer bag size and film type
- 3Set the volumetric cup to the desired fill weight between 5 and 15 g
- 4Adjust the stepper motor for outer bag length positioning to match your bag size
- 5Run ten sample bags and verify fill weight, seal integrity, and hanging ear alignment
- 6Use the reserved connector to link with a nitrogen machine if shelf life extension is required
