Key Benefits
- Produces inner and outer bags simultaneously, reducing cycle time and increasing throughput
- Volumetric cup filling delivers consistent fill weight across 5 to 15 g per bag without manual adjustment
- Ultrasonic sealing avoids heat damage and glue, preserving aroma and preventing film scorching
- Stainless steel food contact parts ensure no contamination and meet hygiene standards
- Stepper motor controls outer bag length with accurate and stable positioning
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation
Application Scenarios
- Coffee roasters packaging small batches of specialty beans in inner and outer bags for retail or direct-to-consumer sale
- Contract packers handling multiple coffee brands with different bag sizes and fill weights on one line
- Roasters transitioning from manual packing to in-house automation with consistent bag weight and seal quality
- Brands requiring nitrogen flushing to extend shelf life of roasted coffee in a sealed double bag
Who It Is For
- Coffee roasters who need to package granule or powder coffee in double-layered bags
- Contract packers serving multiple coffee brands with short batch runs and frequent changeovers
- Brands that require a visible inner bag with a secure outer seal for retail presentation
- Buyers replacing manual filling or older machines that cannot handle dual-layer sealing
Problems It Solves
- Manual filling leads to inconsistent weight and slow output, especially for small batch runs
- Heat sealing damages sensitive coffee film and can cause scorch marks or glue residue
- Single-layer bagging does not provide the protection needed for long shelf life or retail display
- Inconsistent bag length or seal position affects packaging line integration and machine reliability
- Lack of nitrogen flushing capability shortens shelf life of roasted coffee after packaging
Technical Features
- Volumetric cup filling system for 5 to 15 g per bag with consistent output

How It Compares
| Single-layer coffee bag machine | The C19D produces inner and outer bags together, offering better protection and shelf life, but requires more film and a larger footprint |
|---|---|
| Heat-sealed double bag machine | Ultrasonic sealing avoids film scorching and glue residue, but requires an air supply and a stepper motor for positioning |
| Manual bagging line | The C19D replaces a hand-filling team and holds fill weight consistently, but needs a fixed 1200 x 900 mm floor space and trained operator |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the inner and outer film rolls matched to your chosen bag size and material
- 3Set the volumetric cup to the desired fill weight between 5 and 15 g
- 4Adjust the stepper motor for outer bag length and position using the human machine interface
- 5Run ten sample bags and check fill weight, seal quality, and bag length before starting the batch
- 6Use the reserved connector to link with a nitrogen flushing system if shelf life extension is required
