- Forms and seals inner and outer bags simultaneously, reducing line footprint and labour compared to separate machines
- Stepper motor control ensures accurate and stable outer bag length positioning across batches
- PLC control with human machine interface allows simple setup and operation without specialist training
- Ultrasonic sealing avoids heat damage to coffee aroma and maintains a narrow seal edge
- Volumetric cup filling delivers consistent fill weight across 5 to 15 g per bag without manual adjustment
- Supports nitrogen flushing via reserved connector to extend product shelf life in retail packaging
Application Scenarios
- Coffee roasters producing small to medium batches of single-origin drip coffee for direct-to-consumer or retail sale
- Contract packers handling multiple coffee brands with different bag sizes and branding requirements
- Roasters transitioning from manual packing to in-house automation with consistent bag weight and seal quality
- Packaging teams needing to add nitrogen flushing to preserve freshness in sealed drip coffee bags
Who It Is For
- Coffee roasters who need to pack drip coffee bags with inner and outer layers in one machine

How It Compares
| Two separate machines for inner and outer bag packing | The C19D combines both steps into one line, reducing floor space and labour, but requires a single machine footprint of 1200 x 900 mm |
|---|---|
| Heat-sealed drip coffee bag machine | Ultrasonic sealing avoids heat damage to coffee aroma and maintains a narrow seal edge, but requires an air supply for operation |
| Manual inner and outer bag packing | The C19D replaces a hand-filling team and holds fill weight consistency, but needs a fixed power supply and compressed air |
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 film type
- 3Set the volumetric cup to the target fill weight between 5 and 15 g
- 4Adjust the stepper motor for outer bag length positioning using the human machine interface
- 5Run ten sample bags and verify fill weight, seal quality, and bag alignment
- 6Enable nitrogen flushing via the reserved connector if shelf life extension is required
