Key Benefits
- Produces inner and outer bags simultaneously, cutting packaging time by half compared to sequential machines
- Ultrasonic sealing avoids heat damage to coffee aroma and prevents film scorching on sensitive materials
- Volumetric cup filling delivers repeatable fill weight across 5 to 15 g per bag without manual adjustment
- Stepper motor controls outer bag sealing position with high accuracy and stability
- SUS304 stainless steel parts in food contact zones meet hygiene standards for direct product contact
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation in the bag
Application Scenarios
- Coffee roasters packaging flavoured Vietnamese drip bags for export under their own brand
- Blenders producing small batches of single-origin or seasonal coffee with consistent fill weight
- Contract packers handling multiple coffee lines with quick format changeover between bag sizes
- Producers needing nitrogen flushing to preserve freshness in high-value or long-shelf-life products
Who It Is For
- Coffee roasters transitioning from manual or outsourced packaging to in-house drip bag production
- Blenders who need to package granulated coffee with a sealed outer layer for retail or export
- Producers of flavoured or specialty coffee requiring precise fill weight and clean sealing
- Packaging teams replacing older machines that use heat sealing and risk film degradation
Problems It Solves
- Manual or semi-automatic packing cannot maintain consistent fill weight across 5 to 15 g per bag
- Heat sealing damages delicate coffee aroma and can melt thin film layers in multi-layer materials
- Sequential inner and outer bag machines slow down output and increase labour and error risk
- Lack of nitrogen flushing leads to faster oxidation and shorter shelf life in packaged coffee
- Inconsistent bag length or sealing position causes misalignment in packaging lines or retail displays
Technical Features
- Ultrasonic sealing for both inner and outer bags with no heat or adhesive required
- Volumetric cup filling system for consistent 5 to 15 g per bag output
- Stepper motor controls outer bag sealing position for accurate and stable bag length
- PID temperature controller for precise heat management in sealing zones
- PLC control system with human-machine interface for easy operation and monitoring
- All food contact parts made from SUS304 stainless steel for hygiene and durability
- Optional flat cut, date printer, easy tear device, and nitrogen flushing connector
- High specification components including imported cylinders for stable performance

How It Compares
| Single-layer drip bag machine | The C19D adds an outer protective layer for better freshness and retail presentation, but requires more film and setup time |
|---|---|
| Heat-sealed drip bag machine | Ultrasonic sealing avoids film scorching and preserves coffee aroma, but requires an air supply and higher initial component cost |
| Manual bagging line | The C19D replaces a hand-filling team and ensures consistent fill weight, but needs 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 power outlet
- 2Load the inner and outer film rolls matching your chosen 180 mm and 200 mm widths
- 3Set inner and outer bag sizes within the 50-75 mm and 85-120 mm range on the control panel
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run ten test bags and verify fill weight, seal quality, and bag length before batch start
- 6Install optional devices like date printer or nitrogen connector if required for your process
